Catalytic coal gasification catalyst and preparation method thereof

Abstract

The invention belongs to the technical field of catalytic coal gasification catalysts and provides a high-efficiency catalytic coal gasification catalyst and a preparation method thereof. The high-efficiency catalytic coal gasification catalyst takes a complex Ni(NH3)6CO3 as a catalyst precursor, active ingredients are uniformly dispersed on a coal base by adopting an ion exchange technique, and loading capacity of the active ingredients is 2-8%. When the prepared catalytic coal gasification catalyst is applied in a catalytic coal gasification fixed bed reactor, rate of gasification of coal can be effectively improved, and components of coal gas can be improved, so that methane content is increased and utilization rate of the coal is greatly increased.

Description

technical field

[0001] The invention belongs to the field of catalysts, and in particular relates to a high-efficiency coal catalytic gasification catalyst for producing natural gas and a preparation process thereof. Background technique

[0002] As one of the efficient and clean utilization methods of coal, the coal gasification process is favored by people because of its wide range of applications, the ability to obtain product gases of different compositions according to needs, and the use of various types of reactors. A large number of laboratory studies have reached the level of industrial application, but how to further improve the efficiency of coal gasification and optimize the composition of product gas has always been the goal pursued by coal gasification researchers. In order to further improve the efficiency of coal gasification and reduce the gasification temperature, people began to consider coal catalytic gasification more than one hundred years ago.
