Changlian research institute engaged in catalytic cracking catalyst research technical force restructuring into yueyang sansheng chemical co., LTD.

In April of the same year, the research and development of losa-1 light olefin assistant catalyst for increasing yield (propylene assistant for increasing yield) was successful, and the industrial application was successfully completed in no. 1 catalytic unit of changling branch of sinopec, and it was officially put on the market.The research and development of LOSA type propylene additive for increasing production successfully broke the long-term market monopoly of similar foreign products in China. Yueyang sciensun chemical co., ltd. became the first FCC device producing propylene additive for increasing production in China.

LOSA type to increase propylene additives in sinopec changling branch, golmud, petrochemical, jinan branch, luoyang petrochemical, jiujiang petrochemical, Qingdao branch, hainan refining, the north sea branch, yangzi petrochemical, yangzhou petrochemical, zhenhai refining, qingjiang petrochemical, jinshan petrochemical, gaoqiao petrochemical, jinling petrochemical, hangzhou, yangzhou, taizhou, fujian petrochemical, wuhan petrochemical, jingmen branch joint petrochemical refining enterprises successful application, etc. Yueyang sciensun has grown into a long-term stable supplier of sinopec systems.

Set up a wholly-owned subsidiary - yueyang yitian chemical co., LTD.

The 7,000 tons/year solid auxiliary production unit of changlian production site was put into operation, and its capacity was further expanded.

LOSA type propylene stimulant has been used in the catalytic unit of dalian petrochemical company, and has gradually established business relationship with CNPC.

The products have been successfully used in dalian petrochemical company, dushanzi petrochemical company, karamay petrochemical company, qianguo petrochemical company, daqing petrochemical company, jinxi petrochemical company, changqing petrochemical company, yunnan petrochemical company and guangxi petrochemical company, and the company has become a first-class supplier of petrochina system.

The molecular sieve preparation technology obtained a technical breakthrough, the LOSA type increased propylene additives product upgrade completed, began the series production.

The preparation of ZSM - 5 zeolite was a kind of ", "a method of preparation of nanometer molecular sieve ZSM - 5, respectively, and to apply for a patent application in industrial production, LOSA propylene additive to increase production to complete the product upgrade, the second generation to increase propylene LOSA - 100 type additives and the third generation LOSA - 100 - s to increase propylene additives began to put on the market, gradually completed the production of light olefins cocatalyst series production.
