Electromagnetic heating multi-stage catalytic cracking heavy oil fluidized bed

Abstract

The invention provides an electromagnetic heating multi-stage catalytic cracking heavy oil fluidized bed. The electromagnetic heating multi-stage catalytic cracking heavy oil fluidized bed comprises a fluidizing and feeding device, a multi-stage cracking room, a material outlet and a condensation device; the electromagnetic heating multi-stage catalytic cracking heavy oil fluidized bed is characterized in that power is provided by the fluidizing and feeding device through a feeding pump and a gas ballast pump, so that raw materials are pumped into the multi-stage cracking room for catalytic cracking, enter the condensation device through the material outlet for condensation after the catalytic cracking and are collected after the condensation. According to the electromagnetic heating multi-stage catalytic cracking heavy oil fluidized bed provided by the invention, the problems that when an existing fluidized bed is used for carrying out the catalytic cracking on a reactant which is easy to deposit carbon, due to easiness in carbon deposition of the reactant, a catalyst is rapidly inactivated, a reactor pipeline is blocked, and the quality of a reaction product is not high are solved; by utilizing a structure that primary cracking and deep reformed cracking are coupled, the carbon deposition is reduced to the maximum, and the quality of products is increased to the maximum.

Description

technical field [0001] The invention relates to a reactor for cracking liquid reactants prone to carbon deposition, in particular to an electromagnetic heating multistage catalytic cracking heavy oil fluidized bed. Background technique [0002] Fluidized bed refers to the use of carrier gas to blow solid or liquid reactants so that the reactants have a fluidized state. When a fluidized bed is required for catalytic cracking, a solid catalyst is placed in the fluidized bed, and when the reactant passes through the fluidized bed quickly, it contacts with the heated catalyst to generate a cracking reaction. However, the existing fluidized bed can only catalytically crack the reactants in one system, and there will be a dilemma for reactants that are prone to carbon deposition, such as heavy petroleum and bio-oil heavy oil: if you choose a macroporous catalyst, although There is less carbon deposition, but the orderly reforming effect of the catalyst on the reactants is not obv...
