Title:
ポリオレフィン系合成油の調製方法
Document Type and Number:
Japanese Patent JP5175104
Kind Code:
B2
Abstract:
The invention relates to a method for the preparation of the polyolefinic bases of synthetic oils by the cationic oligomerization of olefinic feedstock and can be used in the petrochemical industry. A new method for the preparation of the polyolefinic bases of synthetic oils has been developed, which comprises the steps of conditioning olefinic feedstock, preparing and dosing in a reactor, solutions and suspension of the components of a catalytic system Al(O)-HCl-TBCh, isomerizing alpha-olefins and oligomerizing higher olefins and mixtures thereof under the action of the catalytic system Al(O)-HCl-TBCh, separating spent catalyst, dividing an oligomerizate into fractions and hydrogenating the fractions separated under the action of a catalyst Pd(0.2% w)/A1203+NaOH. The invention provides the improvement of all steps of the method elaborated. For the corrosive activity of products to be removed, a method further comprises a step of the dechlorination of oligomerizate present chlorine-containing oligoolefins with metallic aluminum, triethyl aluminum, alcohol KOH solutions or the thermal dehydrochlorination of chlorine-containing polyolefins in the absence or presence of KOH. For improvement of method technico-economic indices owing to an increase in the yield of polyolefin target fractions having a kinetic viscosity of 2-8 cSt at 100° C., the method further comprises a step of the thermal depolymerization of restricted consumable high molecular polyolefins with a kinetic viscosity of 10-20 cSt at 100° C. to target polyolefins with a kinetic viscosity of 2-8 cSt at 100° C.
