CATALYST FOR NONOXIDATIVE DIRECT CONVERSION OF METHANE, AND METHANE CONVERSION METHOD USING SAME

Title:

CATALYST FOR NONOXIDATIVE DIRECT CONVERSION OF METHANE, AND METHANE CONVERSION METHOD USING SAME

Document Type and Number:

WIPO Patent Application WO/2019/146879

Kind Code:

A1

Abstract:

The present invention relates to a catalyst for nonoxidative direct conversion of methane, and a methane conversion method using the same and, more specifically, to: a catalyst for nonoxidative direct conversion of methane, the catalyst having optimized catalytic characteristics through the regulation of free space between catalyst particles filled in a reactor, thereby maximizing a catalytic reaction rate and simultaneously minimizing coke generation without precise control of the nonoxidative direct conversion reaction condition of methane, and enabling stable catalytic performance to be exhibited even during long-term operation; and a methane conversion method using the same.
