Title:
METHOD FOR PREPARING HYDROGEN-RICH FUEL GAS BY OVERHEATING CATALYTIC CONVERSION OF WASTE ORGANIC-INORGANIC COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/065508
Kind Code:
A1
Abstract:
Provided is a method for preparing hydrogen-rich fuel gas by overheating catalytic conversion of a waste organic-inorganic composite material, relating to an organic-inorganic composite material. The method mainly comprises the following steps: low-temperature vacuum cracking, superheated steam pyrolysis, fuel gas catalytic recombination, fuel gas purification, mechanical crushing-eddy current separation and the like. Compared with the prior art, due to the use of a low-temperature vacuum cracking and superheated steam pyrolysis combined technology, the gasification conversion rate of organic components is increased, and enrichment of cracked oil and cracked coke is avoided. Gas produced by pyrolysis is catalytically reformed, so that the content of combustible hydrogen in fuel gas is increased, and the obtained hydrogen-rich fuel gas has a higher utilization value. The method has the characteristics of strong raw material adaptability, high organic component conversion rate, obvious reduction, easy industrial popularization and application and the like.
