Project necessity analysis

Comonomers are one of the most important uses of α-olefins, accounting for more than
40% of α-olefin consumption.
α-olefin as a comonomer is mainly used in the industrial production of polyolefins, of which 1-butene, 1-hexene, 1-octene and ethylene copolymerization can prepare high-density polyethylene (HDPE), linear low-density polyethylene (LLDPE) and polyolefin elastomer (POE), 1-butene can also be copolymerized with ethylene, propylene to prepare propylene/ethylene/butene ternary random polypropylene or copolymerization with propylene to prepare butene copolymer polypropylene
.

α-olefin, as a comonomer, can develop polyethylene products with higher monomer content and better performance, but its slow localization pace has become the bottleneck
of the development of new polyethylene grades in China.

Over the years, foreign companies only sell products, not technology, long-term monopoly of 1-hexene and 1-octene market, its import price is too expensive, limiting the development and industrial production of new grades of polyethylene in China, but also affecting the replacement of polyethylene products and the improvement
of economic benefits.

Domestic 1-hexene: At present, PetroChina Daqing Petrochemical and Dushanzi Petrochemical have large-scale 1-hexene production equipment, but due to the late start of 1-hexene, there is only 80,000 tons/year production capacity
.

Domestic 1-octene: wax cracking can not get high-purity 1-octene for comonomer, butadiene modulation by methyloctyl ether cracking and ethylene oligomerization production of 1-octene production technology is still in the research and development stage, so so far, the large-scale production of high-purity 1-octene products is still blank in China, must rely on imports to solve
.

Through the introduction of high-tech talents for many years of research and development technology, the Institute of Satellite Chemistry has developed a catalyst suitable for α-olefin production, and after experiments, the ethylene oligomerization method has achieved highly selective production of 1-hexene and 1-octene, and has a high conversion rate
.
After large-scale production, it may break through the monopoly of foreign technology blockade and solve the market demand
for α-olefins.
