Kettle body of polymerizing kettle for producing poly-alpha alkene

Abstract

The invention discloses a kettle body of a polymerizing kettle for producing poly-alpha alkene, and relates to a polymerizing kettle. The kettle body (10) is arranged aslant; an upper rocking arm (2)is arranged at the upper end of the kettle body (10); a connecting rod (1) is arranged at the upper end of the upper rocking arm (2); a C-10 alkene inlet (4) and a boron trifluoride inlet (7) are respectively formed in the upper end of the kettle body (10); a lower rocking arm (15) is arranged at the lower end of the kettle body (10); a spherical head (16) is arranged at the lower end of the lowerrocking arm (15); a poly-alpha alkene outlet (14) is also formed in the lower end of the kettle body (10). According to the kettle body of the polymerizing kettle for producing poly-alpha alkene disclosed by the invention, the kettle body is configured as a sealed structure, the outer part of the kettle body is connected with a positive-negative rotating motor, so that the kettle body is rotated,a stirring column arranged in the kettle body is also rotated under an effect of a weight-bearing block so as to further drive a stirring plate to perform turbulance on a reactant, and thus, the aimof fully catalyzing C-10 alkene by a catalyst boron trifluoride in an airtight environment and difficultly letting the C-10 alkene out are fulfilled.

Description

【Technical field】 [0001] The invention relates to a polymerization reactor, in particular to a reactor body of a polymerization reactor for producing polyalphaolefin. 【Background technique】 [0002] Fischer-Tropsch olefins are obtained through indirect liquefaction of coal, and are liquid coal-to-oil products mainly composed of normal alkanes and alpha olefins. The main components of Fischer-Tropsch synthetic olefins are 50%-60% alpha olefins, 35%-45% carbon five to sixteen sixteen normal alkanes, a small amount of isoparaffins, naphthenes and isomeric olefins, and the impurity is trace moisture Wait. With the development of coal-to-oil technology, the production capacity of Fischer-Tropsch olefins in my country is increasing year by year, and it is economical to use this olefin as a raw material for preparing polyalphaolefin. [0003] In the process of preparing polyalphaolefins, one of the steps is that the catalyst boron trifluoride catalyzes the reaction of carbatenes ...

Problems solved by technology

[0003] In the process of preparing polyalphaolefins, one of the steps is that the catalyst boron trifluoride catalyzes the reaction of carbatenes to generate polyalphaolefins. In this process step, boron trifluoride is used as a catalyst and does not participate in the reaction. The conversion rate of carbadecenes Not less than 98%, because boron trifluoride does not participate in the reaction as a catalyst, so an appropriate amount of boron trifluoride and carbadecene can be added in a closed container to make boron trifluoride fully catalyze the carbadecene. After the reaction, the boron trifluoride is emptied to obtain the product polyalphaolefin. When using a traditional reactor for reaction, a motor installed outside the reactor needs to be driven by a stirring paddle extending into the reactor to stir the carbadecene in the liquid phase to increase its and The contact of boron trifluoride enables boron trifluoride to fully catalyze carbatenes, but it is easy to leak the reactants in the kettle body from the joint between the stirring rod and the kettle body, which not only easily causes poisoning of the operator, And the contact is not enough, the reaction efficiency is low, and it is easy to cause environmental pollution
