Calcium-based compound catalyst and loading method thereof

Abstract

The invention provides a calcium-based compound catalyst and a loading method thereof and relates to the technical field of catalytic coal gasification. The calcium-based compound catalyst has higher catalytic efficiency in both gasification reaction and methanation reaction, can realize gasification, conversion and methanation reaction coupling in a gasification furnace, and improves the content of methane in product gas. The calcium-based compound catalyst disclosed by the invention comprises a calcium-containing substance and a transition metal-containing substance. The calcium-based compound catalyst and the loading method thereof, disclosed by the invention, are applicable to the catalytic coal gasification process.

Description

technical field

[0001] The invention relates to the technical field of coal catalytic gasification, in particular to a calcium-based composite catalyst and a loading method thereof. Background technique

[0002] Coal catalytic gasification technology is an important way to cleanly and efficiently utilize coal. In the process of coal catalytic gasification, potassium-based catalysts are usually used to catalyze the gasification reaction to generate the target product. However, since the potassium-based catalyst is very expensive, and its alkalinity is strong and easy to corrode, it often needs to be recovered and recycled through processes such as washing and digestion, and the recovery process consumes a lot of energy and water, that is, the cost of the potassium-based catalyst is relatively high. High, complex recycling process and other shortcomings.

[0003] In order to overcome this shortcoming of potassium-based catalysts, technicians have gradually focused on calcium...
