A self-dusting pyrolysis and catalytic cracking reactor

Abstract

The invention belongs to the technical field of pyrolysis and cracking of fossil fuel and in particular relates to a self-dust-removal type pyrolysis and catalytic cracking reactor which is mainly specific to resources such as oil shale and coal and used for preparing flammable gas and semicoke products. The invention, aiming at overcoming the defects of the prior art, designs and develops a self-dust-removal-type pyrolysis and catalytic cracking reactor. In the reactor, a pyrolysis chamber and a cracking chamber are designed in an integrated manner, oil gas produced in the pyrolysis chamber enters a particle bed dust removal device, after dust removal is carried out by the particle bed dust removal device, clean oil gas enters the cracking chamber to be deeply cracked, rear-end dust removal pressure is reduced, macromolecular tar molecular is cracked into micromolecular gaseous hydrocarbon, and a large amount of hydrogen is produced in a catalytic cracking manner, so that the problem that pyrolyzed oil contains dust is avoided and clean and efficient utilization of the fossil fuel is really realized.

Description

technical field [0001] The invention belongs to the technical field of pyrolysis and cracking of fossil fuels, and specifically relates to a self-dusting type pyrolysis and catalytic cracking reactor mainly aimed at resources such as oil shale and coal, and is used for producing combustible gas and semi-coke products. Background technique [0002] The world's oil and gas resources are gradually decreasing and increasingly scarce, especially in my country, which must rely on a large amount of imported crude oil, which is related to the issue of national energy security. However, my country has very rich oil shale and coal resources. At present, my country's pyrolysis shale oil production ranks first in the world, and there is a trend of increasing year by year. The existing oil shale and coal pyrolysis furnaces mainly include Fushun Furnace, Sanjiang Gas-fired Square Furnace, Dagong’s Solid Heat Transfer Furnace, Estonia’s Galoter Furnace, Australia’s ATP Furnace and United ...

AI Technical Summary

Problems solved by technology

The main purpose of the existing pyrolysis furnaces is to produce oil products, but most of the pyrolysis furnaces, especially those that use pulverized coal as raw materials, contain a lot of dust in the pyrolysis oil, which makes it difficult to effectively process the pyrolysis oil. Utilization, the value of pyrolysis oil is not high, etc.
