Methane chloride cleaner production technology has been a breakthrough

Major scientific and technological projects in Chongqing - the key technology of the production of key technologies for the clean production of methane chloride. The project to achieve the methane chloride two chief product carbon tetrachloride and hydrogen chloride gas resource, high value utilization, will promote the sustainable and healthy development of China's methane chloride industry.
The reporter understands, methane chloride cleaner production key technology research and application projects bear the Chongqing days of the original Chemical Co., Ltd., focusing on carbon tetrachloride alcoholysis of preparation of methyl chloride process and hydrogen chloride gas recovery utilization technology expand the research, currently has developed a new type of catalyst, the catalyst can make carbon tetrachloride transformed to methyl chloride, the conversion rate can reach more than 90% and the service life of the catalyst over 3000 hours. In addition, they also developed a hydrogen chloride gas special adsorbent, enabling hydrogen chloride collection rate of more than 90%, and which is used for the production of trichlorosilane, the added value of the product is much higher than that of hydrochloric acid product.
At present, the project has won the national invention patents, the formation of a corporate standard two. The scientific and technological achievements of the project are being implemented in succession. At that time, only two recovery of methane chloride by year chief product can add value about 20000000 yuan for the enterprise.
It is understood that methane chloride is an important chemical raw materials and organic solvents, and chlor alkali industry an important deep processing products. However, the way the two chief product carbon tetrachloride and hydrogen chloride always restrict the development of the industry. Carbon tetrachloride is a chemical that can destroy the ozone layer, has been the international community to prohibit the production and use of. Therefore, the way to find the carbon tetrachloride is a major issue facing the methane chloride industry.
Hydrogen chloride gas is another by-product of methane chloride. The traditional treatment method is used to generate hydrochloric acid. But in recent years, China has a serious excess hydrochloric acid production capacity, the market is sluggish, extremely easy to cause hydrochloric acid, so as to affect the normal production of methane chloride, and hydrochloric acid value is not high.
