Abstract

The invention relates to the field of reaction equipment, and discloses a reactor, wherein the reactor comprises: a shell (3), a feed zone (23), a mixing zone (8), a reaction zone (9) and a collection zone (24), wherein the mixing zone (8) is provided with a mixing channel (14) extending along the first direction, and the reactor includes a mixing channel extending from the outside of the shell (3) to the mixing channel The fluid distribution pipe (17) in (14), one end of the fluid distribution pipe (17) located in the mixing channel (14) is connected with a fluid distributor (16). The reactor provided by the present invention can realize the continuous and high-efficiency mixing of the reaction system by designing the structure of the mixing channel and the mixing method therein, can keep the flow of the fluid close to the plug flow, and ensure the consistency of the residence time of the reaction fluid as much as possible. Avoid undesired product selectivity due to residence time distribution.

Description

technical field [0001] The invention relates to reaction equipment, in particular to a reactor. Background technique [0002] Poly-α-olefin synthetic oil (PAO) is a high-grade lubricating oil base oil, which has important uses in the fields of military industry, aviation and aerospace. PAO has the characteristics of high viscosity index, low volatility, low fluidity and good shear performance, and has good oxygen stability under high temperature conditions. [0003] Some methods for synthesizing PAOs are disclosed in the prior art, including: [0004] 1. The method for synthesizing PAO intermittently in parallel with two kettles, wherein, the method is based on BF 3 As a catalyst, alcohol is used as an initiator, under the reaction conditions of 0-80°C and 0-1MPa, react for 1-6 hours, and PAO can be obtained, and the tetramer (PAO-4) in the product is the most; [0005] 2. A method for synthesizing PAO in two consecutive stages, wherein the first stage adopts a continuous...
