With the further development of China's refining ethylene, China's carbon 4 resources will be further increased, and high-purity isobutylene will be produced from the cracking of MTBE and MTBE, producing butyl rubber and methacrylic acid with high technology content, high added value, and good market prospects. Refined chemical products such as methyl esters and polyisobutylene are also favored by the market. MTBE is expected as a chemical raw material, the future consumption will have a larger increase.
Clean Gasoline Demand Demand In July 2005, China began to implement a new standard for gasoline for motor vehicles, which puts forward more stringent requirements for the content of olefins, aromatic hydrocarbons and sulfur in gasoline. The oxygen content of gasoline is limited to 2.7% or less. Due to the lowering of sulfur and olefin reduction, the octane value of gasoline is greatly lost. In order to achieve the balance between the octane number of gasoline and the requirement for clean fuel, MTBE will still be an important octane improver in China and its demand will be faster. increase.
In 1990, China's gasoline production was 21,161,000 tons, MTBE's average addition was 0.40%, and most of the gasoline was still leaded gasoline; in 2000, China's gasoline production was 39.947 million tons, MTBE's average added amount was 2.25%, leaded gasoline The proportion decreased; in 2006, China's gasoline production was 55.114 million tons, and the average MTBE addition was 2.59%. From the above data, we can see that with the upgrading of China's oil quality, the consumption and the proportion of MTBE are gradually increasing.
Slower growth of oil application In 2007, China's MTBE production was estimated at 1.7 million tons. It is estimated that by 2010, China's gasoline production will reach 64.2 million tons, of which ethanol gasoline production will be about 20 million tons. Based on this forecast, the demand for MTBE for oil products in China will be about 2 million tons in 2010 (the MTBE addition ratio is calculated as 4.5%). However, there are still many uncertainties in the above forecast. The growth rate of gasoline production and the process of popularization and application of methanol gasoline, as well as the introduction of relevant national policies, will affect MTBE's demand.
China's oil refining industry is in a period of development. The growth rate of oil product demand ranks first in the world. Coupled with the upgrading of oil products and emission requirements, as well as the increase in the volume of imported high-sulfur crude oil, the overall demand for MTBE in China will grow steadily in the future. . However, with the development of alternative fuels in China, and the improvement of processing capabilities such as catalytic reforming and etherification in China, especially the application of ethanol gasoline and methanol gasoline, will reduce the dependence on petroleum gasoline, so it is expected that China's MTBE application in oil products in the future. The demand growth rate will slow down.
The gradual increase in chemical consumption With the continuous increase of China's carbon four resources, MTBE as a raw material for chemical production, consumption will have a greater increase. Its main application areas include:
Butyl rubber Butyl rubber is an important rubber species for the production of automotive inner tubes and radial tire inner liners. It is also an important raw material for manufacturing medical stoppers and sealing products. According to China's relevant industrial policies, China will continue to vigorously develop radial tires in the coming years. Therefore, the development prospects of butyl rubber and halogenated butyl rubber are optimistic. It is expected that by 2010, China's butyl rubber demand will reach 200,000 tons, and the demand in 2015 will reach 350,000 tons.
MMA MMA is mainly used for the production of polymethyl methacrylate (PMMA) and polyvinyl chloride processing aids ACR, MBS and others. As an important organic monomer, MMA is in the stage of development and growth in China and has a good market prospect. It is estimated that the demand for MMA in China will be about 350,000 tons in 2010 and 550,000 tons in 2015.
Polyisobutylene At present, the main application field of polyisobutylene in China is lubricating oil additive. Secondly, it is used alone as a two-stroke internal combustion engine oil or lubricating oil viscosity index improver. Medium-molecular polyisobutylene is usually used. It is estimated that the demand for polyisobutylene in China will be approximately 60,000 tons in 2010, and it is expected to reach 100,000 tons in 2015.
Nicotinamide from tert-butylamine synthesized by tert-butylamine is a sulfonylurea herbicide and a side chain amino acid synthesis inhibitor. The obtained NS and TBSI are excellent rubber accelerators, and can also be used for the production of pharmaceuticals and used as additives for dyes and lubricants. And production of paint intermediates. Among them, vulcanization accelerator NS is the most important green product in current rubber chemicals and has become the leading product of rubber accelerators in Europe and the United States. With the rapid development of the rubber processing industry and the improvement of environmental protection requirements, the demand for environmentally friendly vulcanization accelerators such as NS will have greater development, and the demand for high-purity isobutylene will also have greater growth.
In addition, polyisobutylene amine used as the main agent of gasoline detergent, tert-butyl phenol series antioxidant with high purity isobutylene as raw material, organic intermediate methallyl chloride and trimethylacetic acid, etc. More optimistic.
On the whole, with the increase of China's carbon resources, although there are many uncertainties in the future application of MTBE in gasoline addition, the consumption for chemical production will increase significantly and the market prospects are still promising.
MTBE: optimistic outlook for chemical applications
With the European Commission's confirmation that methyl tertiary butyl ether (MTBE) does not pose a threat to health, MTBE, previously listed as a possible carcinogen by the US Environmental Protection Agency, will be used with confidence and will continue to be the main octane improver for clean gasoline. .
