Alkylation process of 85 ^OC b.p. gasoline fraction with C3-C4 gas coking of catalyst cracking has been studied.
Gasoline output increased for 10.7% by mass and octane number for 3 points. With the purpose of obtaining highoctane components of motor oils, the process of oxyalkylation of 85 ^OC b.p. coking gasoline fraction with methanol (T = 120 ^OC, p = 2.5 MPà) has been studied. Alkyl-methyl ether increased for 9.2 by mass and octane number for 5–6 points.
Oxyalkylation process of 130 ^OC b.p. gasoline catalyst cracking with ethanol has been researched as well. The maximum yield of alkyl-ethyl ethers (16.37 % by mass) is observed in T = 90 î Ñ and p = 0.2 MPà. During oxyalkylation product compounding with 130 ^OC b.p. heavy gasoline fraction of catalytic cracking, benzene with 84–85 points octane number by motor method is obtained as well.
