coal to olefins

The coal-to-olefins industry chain we currently refer to actually refers to the production of methanol through coal gasification, and then the synthesis of olefins from methanol through the MTO process. Since my country's per capita polyolefin consumption is only 5 kg of polyethylene and 4.5 kg of polypropylene, it is far lower than that of developed countries. * * level, therefore, China’s demand potential for polyolefin products is huge. At the same time, due to my country's current high dependence on foreign polyolefins (PE was 50.1% and PP was 36.7% in 2005 ； In 2006, PE was 44.69% and PP was 34.33%). Therefore, as a direct extension of the coal-to-methanol industry chain, coal-to-olefins can not only effectively expand the downstream market demand for methanol, but also diversify my country's olefin production raw materials and improve the self-sufficiency level of domestic resin raw materials. Outlook on relevant policies for the coal-to-olefins industry from 2007 to 2010. Coal chemical industry policies are currently being formulated and improved. They will be divided into seven parts and are expected to be released by the end of 2007 or early 2008. After the introduction of this policy, the entry threshold for the coal chemical industry, which often requires billions of yuan in investment, will not be lowered. In recent years, due to the rise in oil prices, the cost advantage of using coal as raw material to produce chemical products has become prominent, and coal chemical projects have been launched in various places. In order to curb this impulse of blind investment, in July 2007, * * * * The Development and Reform Commission issued the "Notice on Strengthening the Construction and Management of Coal Chemical Projects to Promote the Healthy Development of the Industry", requiring all localities to no longer approve coal-to-liquid projects with an annual output of less than 3 million tons, methanol and dimethyl ether projects with an annual output of less than 1 million tons, and coal-to-olefin projects with an annual output of less than 600,000 tons. This means that launching a new coal chemical project will require at least billions of yuan in investment. This restriction makes companies with smaller capital and insufficient strength have to stay away from the coal chemical industry. To this end, some companies have proposed to relevant departments that they hope to lower the entry threshold for the coal chemical industry. and * * * * The Development and Reform Commission stated that the coal chemical industry is a technology- and capital-intensive industry that involves a wide range of areas, complex engineering construction, and difficult implementation. There are still many uncertainties and risks in the development of the industry. The gate cannot be opened and must develop steadily. * * The Development and Reform Commission stated that based on the development of the national economy and market supply and demand, the development of coal-based fertilizers and other products is currently encouraged, and the steady development of coal-based oil products, methanol, dimethyl ether, olefins and other petroleum substitute products. Among them, coal liquefaction is still in the demonstration stage and should be promoted after success. Therefore, the entry threshold of 3 million tons is the highest among various coal chemical products. On the other hand, water resources are also an important constraint on the development of the coal chemical industry. * * * * The person in charge of the Development and Reform Commission said that according to the coal chemical industry policy, the development of coal chemical industry must "measure the water." The annual water consumption of large-scale coal chemical projects usually reaches tens of millions of cubic meters, and the water consumption per ton of products is more than ten tons, which is equivalent to the water resources occupied by hundreds of thousands of people in some areas or the water resources retained by more than 100 square kilometers of land area. Large-scale advance planning of coal chemical projects in some areas may, on the one hand, lead to overcapacity. On the other hand, it may break the fragile water balance in the region and directly affect the stable development of the local economy and society and the protection of the ecological environment. .Note$#, $ $
