Title:
REFORMING CATALYST, METHOD FOR PREPARING SAME, AND PROCESS FOR MANUFACTURING SYNTHESIS GAS
Document Type and Number:
WIPO Patent Application WO/2013/187436
Kind Code:
A1
Abstract:
Provided are: a reforming catalyst which can make a hydrocarbon-based raw material gas react with carbon dioxide and/or steam while minimizing the deposition of carbon, and thus enables efficient production of hydrogen and carbon monoxide; a method for preparing the same; and a process for manufacturing a synthesis gas. The present invention pertains to a method for preparing a reforming catalyst which comprises SrTiO3, SrCO3 and Co as main components, said method including a step for forming a Co-Sr2TiO4 or Co-Sr3Ti2O7 solid solution which is a solid solution of Co in an Sr/Ti composite oxide and then making carbon dioxide act on the solid solution to form SrTiO3, SrCO3, and Co and/or a Co-containing oxide. In the catalyst, the content of Sr is adjusted to 1.7 to 2.6 moles per mole of Ti. The present invention also pertains to a process for manufacturing a synthesis gas, said process comprising passing a gas which comprises a raw material gas and carbon dioxide and/or steam through a reformer packed with the reforming catalyst to manufacture a synthesis gas that contains both carbon monoxide and hydrogen.
