According to this disclosure, there is provided a pyrolysis reaction system and a direct non-oxidative methane coupling process using the same by which it is possible to reach the selectivity for good Chydrocarbons and at the same time to inhibit coke from being generated while a good methane conversion is maintained during direct conversion of methane into Chydrocarbons through non-oxidative pyrolysis.

Reactors for preparing valuable hydrocarbons and hydrogen from methane through non-oxidative pyrolysis

A hydrofinishing catalyst according to the present invention includes an amorphous silica-alumina support; and a hydrogenated active metal supported on the support, and has an Al composition having a total mass (wt %) of Al and Si as a denominator and a mass (wt %) of Al as a numerator with respect to a reference line, which is a straight line passing through the center of a cross-section of the support, locations evenly spaced apart along the reference line are sequentially numbered, where composition uniformity, which is defined as UN by the Al composition at the i-th location and an average Al composition at the cross-section of the support passing through the center of the support, is 3.0 or less.
