Rapid Development of Dicyclopentadiene: Breakthroughs in Downstream Technologies Are Key □ Jilin Design Institute of CNPC Northeast Refining & Chemical Engineering Co., Ltd., Yu Chunmei; Jilin Fuman District Environmental Protection Bureau, Xu Zhijun I. The Rapid Growth of China’s DCPD Industry In 2009, the world’s production capacity for dicyclopentadiene (DCPD) was 580,000 tons per year, with actual production amounting to 405,000 tons. The main manufacturers include Dow, ExxonMobil, Shell, Equistar, and Texmark, among others (see Table 1 for details). Back then, the global production of DCPD was 416,000 tons, while consumption was 394,000 tons. The United States, Western Europe, Japan, and China led the world in terms of production and consumption, accounting for 35%, 19%, 16%, and 15% of total consumption respectively. According to CEH’s projections, the global demand for DCPD will grow at an average annual rate of 3.4% from 2009 to 2014. Among them, China has the fastest growth in consumption, with an average annual growth rate of 5.9% (the actual growth rate is higher than expected due to the rapid development of the carbon pentane separation and deep processing industries). The average annual consumption growth rate in the United States and Western Europe is 3%, while in Japan it is 1.8%. The supply, demand, and forecasts of DCPD in the major regions of the world are shown in Table 2. 　　In 2009, there were around 20 DCPD manufacturers in China, with a production capacity of 165,000 tons per year (see Table 3 for details), and the actual output was approximately 65,000 tons. DCPD mainly comes from carbon pentane separation units. At present, the level of carbon pentane separation in China varies; some enterprises only manage to separate DCPD, with a purity of 80% to 85% ； Some other companies, in addition to DCPD, also isolate isopentadiene (content ≥65%) and isoprene (content ≥98.5%) ； There are only four fully separated enterprises: Shanghai Petrochemical, Shandong Yuhuang, Zibo Luhua, and Maoming Luhua. In our country, the production capacity for DCPD is concentrated in enterprises that carry out full separation of C5 compounds; in 2009, the output of these enterprises reached 52,000 tons, accounting for approximately 80% of the total production. 　　According to the current plans for the construction of carbon pentane separation facilities, China’s capacity for carbon pentane separation and processing will increase by 1 million tons per year by 2012, while the processing capacity for DCPD will increase by nearly 180,000 tons per year; as a result, the total capacity for DCPD will reach 350,000 tons per year. II. Large potential for DCPD demand in the domestic market 　 Overseas, DCPD is primarily used in the production of highly saturated transparent hydrocarbon resins, followed by unsaturated polyesters and ethylene norbornene. Another current application trend for DCPD in the world is in the production of cycloolefin copolymers, which are formed by copolymerizing ethylene and derivatives of DCPD. Thanks to their good transparency, they can compete with polycarbonate in industries such as the manufacture of optical instruments. 　　The main market for DCPD in our country is unsaturated polyester resin (UPR), accounting for over 60% of its consumption. In our country, the purity of DCPD obtained through the separation of carbon pentane is generally around 80%; most of this DCPD is used directly to replace the more expensive maleic anhydride and phthalic anhydride in the production of modified UPR, thereby reducing the production costs of resins ； A small portion is used directly in the production of C5/C9 mixed petroleum resins and DCPD resins ； The remaining DCPD is mainly used to produce fine chemical products such as adamantane (tricyclodecane), 2-chloro-5-chloromethylpyridine (CCMP), and ethylenedecynene (ENB), after being refined to a purity of over 95%. 　　1. Modified UPR 　　Currently, modifying UPR using DCPD to improve the properties of resins has become an important area in the advanced processing of petrochemicals. DCPD-modified UPR has been widely produced and applied in developed countries and regions such as the United States, Europe, and Japan. At present, there are over 160 UPR resin manufacturers in China, with an annual production volume of more than 1.5 million tons, making China the country with the highest global production and consumption of UPR resin, surpassing the United States. In recent years, to cope with rising prices of raw materials such as phthalic anhydride and maleic anhydride, UPR has turned its attention to DCPD, which is derived from the C5 streams produced as a byproduct of ethylene production. In 2009, China’s UPR production was 1.53 million tons, of which approximately 60,000 tons were used as a substitute for phthalic anhydride in the production of DCPD. 　　2. Petroleum resins 　　Using DCPD as a raw material, alicyclic C5 petroleum resin and C5/C9 copolymerized petroleum resin can be produced, which are mainly used as viscosity enhancers in rubber compounding and for modifying paints. Currently, 4 to 5 companies in China have DCPD petroleum resin production facilities; however, due to limitations in the availability of raw materials, the operating rate of these facilities is low. In 2009, China’s consumption of DCPD was approximately 15,000 tons. With the growing consumption of petroleum resins and the shift of production capacity from abroad to China, the consumption of DCPD for petroleum resins will increase significantly. 3. Polydicyclopentadiene Petroleum resins synthesized from DCPD with a purity of around 80% are known as dicyclopentadiene resins, and they are primarily used in the production of paints, inks, synthetic rubbers, etc. Petroleum resin polymerized using DCPD with a purity of ≥99% is known as polydicyclopentadiene; it is a transparent resin primarily used in manufacturing RIM products with excellent mechanical properties and complex shapes. Developed countries such as Japan and the United States have achieved industrial production of polydicyclopentadiene, which is used to manufacture transparent products such as films for liquid crystal displays. China began producing and using polydicyclopentadiene in 2006, but the production volume is low; there is great potential for development in this field in the future. 　　4. Fine chemicals • ENB is the most widely used third monomer for the industrial synthesis of EPDM, owing to its fast sulfidation rate, high yield, and low incidence of side reactions. It is obtained by first forming vinyl norbornene through a Diels-Alder reaction between DCPD and 1,3-butadiene, and then via isomerization. At present, only Dàyǔ Chemical Co., Ltd. in Jilin City in China possesses a production facility capable of manufacturing 2,000 t/a of ENB, but the production is unstable and the operation rate is low ； There is only one producer of EPDM, namely Jilin Petrochemical Company, with a production capacity of 45,000 tons per year; demand for this product exceeds supply, and in 2009 domestic imports reached 162,000 tons. Given the ongoing upward trend in the demand for ethylene-propylene rubber in our country, the potential demand for ENB is relatively high. 　　•Pesticides: In recent years, there has been a rapid increase in demand for low-toxicity insecticides such as imidacloprid and acetamiprid. The technology for producing the intermediates 2-chloro-5-chloromethylpyridine (CCMP) used in the synthesis of imidacloprid and acetamiprid via the cyclopentadiene-propionaldehyde method, which was developed independently in China, offers advantages such as high product purity and low costs. CCMP produced in China is popular in both domestic and international markets. III. Breakthroughs are needed in downstream production technologies. In the coming years, new carbon pentane separation units will be put into operation in China, increasing the supply of DCPD; therefore, these new units need to find a use for this substance. At present, the consumption of DCPD in China is still mainly concentrated in unsaturated resins and purified dicyclopentadiene. Among them, the consumption of biscyclodiene is concentrated in three areas: high-grade unsaturated resins, CCMP intermediates, and adamantane. 　　The applications of downstream products of DCPD in our country differ from those abroad. Hydrogenated unsaturated resins abroad (including DCPD hydrogenated resins and C5/C9 copolymerized petroleum resins) account for a large proportion of consumption ； High-purity injection-molded products also require a large amount of polyDCPD, yet the use of DCPD in these areas remains undeveloped in China. Therefore, in these two fields, DCPD still has great room for development in the future. Overall, the industry with the greatest potential for development in DCPD is hydrogenated petroleum resin. China relies on imports for high-grade petroleum resin, and these import volumes are increasing year by year; however, there are currently challenges related to the difficulty of developing such technologies as well as strict technical restrictions imposed by foreign countries. Other industries, such as polyDCPD, cycloolefin copolymers, ENB, and similar products, also require technological breakthroughs.
