Catalyst structure for syngas production, syngas production device provided with said catalyst structure for syngas production, and production method of catalyst structure for syngas production

Abstract

A catalyst structure for syngas production which suppresses reduction in catalyst activity to enable efficiently producing syngas that contains carbon monoxide and hydrogen, and a syngas production device provided with said catalyst structure for syngas production are provided. This catalyst structure (1) for syngas production, used when producing a syngas that contains carbon monoxide and hydrogen, is provided with a carrier (10) with a porous structure configured from a zeolite compound, and at least one catalytic material (20) present in the carrier (10), wherein the carrier (10) has passages (11) that communicate with each other, the catalytic material (20) is metal micro-particles and is present at least in the passages (11) of the carrier (10).

Description

technical field [0001] The present invention relates to a catalyst structure for producing synthesis gas used when producing synthesis gas containing carbon monoxide and hydrogen by contacting methane-containing gas with carbon dioxide, a synthesis gas production device equipped with the catalyst structure for producing synthesis gas, and synthesis gas A method for producing a catalyst structure for production. Background technique [0002] In recent years, as a countermeasure against global warming, a technique (dry reforming) of bringing carbon dioxide, which is a causative substance of global warming, into contact with methane to convert it into a synthesis gas containing carbon monoxide and hydrogen has attracted attention. [0003] As a catalyst used in the production of such a synthesis gas, for example, Patent Document 1 discloses an oxygen-deficient perovskite-type composite oxide containing Mn, a predetermined alkaline earth metal, etc. as a carrier, and uses Nicke...

AI Technical Summary

Problems solved by technology

In the catalyst disclosed in Patent Document 1, since the metal is carried on the surface of the carrier, the catalyst particles are aggregated at high temperature, and the catalytic activity tends to decrease, and the catalytic activity cannot be said to be sufficient.
