System for coproduction of nitrogen-containing heterocyclic chemicals and nitrogen-doped carbon through nitrogen-rich catalytic pyrolysis

Abstract

The invention belongs to the field of organic solid waste nitrogen-rich pyrolysis, and discloses a system for coproduction of nitrogen-containing heterocyclic chemicals and nitrogen-doped carbon through nitrogen-rich catalytic pyrolysis. The system comprises an organic solid waste nitrogen-rich pyrolysis activation subsystem, a nitrogen-containing compound catalytic conversion subsystem and an ammonia gas recycling and energy supply subsystem; the organic solid waste nitrogen-rich pyrolysis activation subsystem is used for enabling the organic solid waste to generate nitrogen-rich pyrolysis volatile matters and a solid product; the nitrogen-containing compound catalytic conversion subsystem is used for carrying out catalytic conversion upgrading on the nitrogen-rich pyrolysis volatile matters to obtain liquid nitrogen-containing heterocyclic chemicals and gaseous nitrogen-rich pyrolysis gas; and the ammonia gas recycling and energy supply subsystem is used for separating and purifyingthe nitrogen-rich pyrolysis gas. By improving the structures, arrangement modes, the matched working modes and the like of all components in the system, the problems that the selectivity and the yieldof organic solid waste nitrogen-rich pyrolysis liquid products are low, and the porosity and the nitrogen content of nitrogen-doped carbon are not high can be effectively solved.

Description

technical field

[0001] The invention belongs to the field of nitrogen-enriched pyrolysis of organic solid wastes, and more particularly relates to a system for co-producing nitrogen-containing heterocyclic chemicals and nitrogen-doped carbon through nitrogen-enriched catalytic pyrolysis. Background technique

[0002] In recent years, the rapid development of my country's economy has also been accompanied by a series of environmental problems. Among them, the problem of garbage siege has been a hot topic in recent years. It is a general consensus to strive to solve the problem of garbage pollution quickly, efficiently and with high quality. Pyrolysis is an important thermochemical method, which can effectively and harmlessly convert organic solid waste into gas, liquid and solid carbon products that are easy to be used later. However, if the organic solid waste is only treated by simple pyrolysis, the added value of the three-state product obtained is not high, resulting in a...
