High-performance domestic ethylene glycol catalysts from Gaohua Chemistry recognized Author/Source: China Chemical Industry News Date: 2016-11-04 Clicks: 60 In October 2016, Xinjiang Tianzhi Chenye Chemical Co., Ltd., a subsidiary of Xinjiang Tianye (Group) Co., Ltd., and Beijing Xinggao Chemical Technology Co., Ltd. formally signed contracts through a bidding process to purchase DMO synthesis catalysts and EG synthesis catalysts for ethylene glycol production facilities. In Xinjiang Tianye’s 250,000 tons per year ethylene glycol production facility using syngas, aside from the catalyst for the first unit with a capacity of 50,000 tons per year which is imported from Japan, all other catalysts are products manufactured by High Chemistry (Jiangsu) Chemical New Materials Co., Ltd. Data from four years of industrial operation show that the domestically produced catalysts with high chemical activity exhibit stable performance, high conversion rates, and a long service life, earning the trust and praise of customers. Gaochemical (Jiangsu) New Chemical Materials Co., Ltd. is a specialized catalyst manufacturing plant established with investment from Beijing Xinggao Chemical Technology Co., Ltd.; it provides catalysts for the syngas-to-ethylene glycol technology (referred to as CTEG technology) owned by the Gaochemical consortium. The designed production capacity of the plant is 3,000 tons per year, of which the designed capacities for the DMO synthesis catalyst and the EG synthesis catalyst are 1,500 tons per year respectively. The DMO synthesis catalyst has passed the evaluation by Ubiquitous Corporation, its performance exceeding that of imported products by a large margin; it has since been sold back to Japan where it is being used steadily in Ubiquitous’ production facilities. Since the factory began commercial operation in early 2013, the DMO synthesis catalysts and EG synthesis catalysts it produces have been continuously used in the Tianye plants in Xinjiang. As of October 2016, the first-generation DMO synthesis catalyst in a single reactor had been in continuous use for over 35 months, with a temperature increase of less than 10°C; the selectivity remained at 99%, and the STY yield was above 600 g/l per catalyst hour ； The expected normal service life is well over 3 years, far exceeding that of other catalysts of the same type. The second-generation DMO synthesis catalyst has been in use since January 2016, and after 10 months of continuous operation, it currently performs better than the first-generation catalyst. The single-furnace EG synthesis catalyst has been in continuous use for over 16 months, operating at a temperature of 180–185°C with a selectivity of 98%–98.5%; its expected service life is more than 1.5 times that of other similar catalysts. The ethylene glycol plant in Xinjiang Tianye utilizes high-performance, long-lasting chemical catalysts. In addition to ensuring stable production and facilitating operation, their overall cost continues to decrease as their service life extends, thereby delivering reliable economic benefits to the owners. Each ton of the high-performance DMO synthesis catalyst can produce over 8,000 tons of ethylene glycol, which is 2 to 4 times more than that of other similar catalysts. Each ton of the high-chemical EG synthesis catalyst can produce over 4,200 tons of ethylene glycol, which is twice as much as that produced by other similar catalysts. According to current data from industrial operations, plants that utilize the CTEG technology along with catalysts from high-quality chemical manufacturers can keep the catalyst cost per ton of ethylene glycol below 200 yuan. Gao Chemical has established a catalyst research institute in Nantong, dedicated to improving catalyst performance and reducing production costs. Through years of continuous research and development, new generations of ethylene glycol catalysts have been upgraded one after another. With the use of high-performance second-generation catalysts, and as performance and lifespan further improve, the overall cost of catalysts per ton of ethylene glycol is expected to drop below 150 yuan, thereby laying a solid foundation for enhancing the competitiveness of ethylene glycol production facilities. In addition, the Gaochemical Nantong Catalyst Research Institute is working on the development of other coal chemical catalysts, with the aim of introducing advanced process technologies and innovative production concepts to leverage its advantages. Xinjiang Tianye’s ethylene glycol plant uses CTEG technology. This technology originated from Ube Industries and was jointly developed and promoted by the Kako Chemical Consortium. To date, the Gao Chemical Consortium has signed 12 technology transfer agreements, resulting in a total capacity of 2.65 million tons per year. Furthermore, the projects that have been put into operation using CTEG technology fully meet the industrial requirements of safety, stability, longevity, full capacity, and excellence. Gao Chemical Consortium can provide process packages in various capacities, including 200,000 tons per year, 300,000 tons per year, 400,000 tons per year, 600,000 tons per year, and 1.8 million tons per year. Upholding the spirit of craftsmanship to provide owners of CTEG technology with the most advanced catalysts and precise, comprehensive technical support is the ongoing goal of the Gaoche Chemical Consortium.
