Title:
METHOD FOR PREPARING SYNTHESIS GAS WITH HIGH CARBON MONOXIDE CONCENTRATION
Document Type and Number:
WIPO Patent Application WO/2023/030367
Kind Code:
A1
Abstract:
The present invention provides a method for preparing a synthesis gas with a high carbon monoxide concentration. The method comprises the following steps: filling a reactor with a catalyst; and inputting a feed gas and water into the reactor for contact with the catalyst so as to convert same into a high-CO-concentration synthesis gas containing CO and H2, wherein the catalyst is a catalyst for the conversion of CO2 and CH4, and the feed gas is a gas mixture of CO2 and CH4, or a gas mixture of CO2, CH4 and H2. In the present invention, recovered CO2 is reacted with methane, H2 with a certain concentration is blended optionally, and under the action of the catalyst for the conversion of CO2 and CH4, the high-CO-concentration synthesis gas is produced; and CO is extracted therefrom by means of pressure swing adsorption (PSA) at room temperature, which has good economic benefits.
