MANGANESE-ALKALI-BASED CATALYST ON ORDERED MESOPOROUS SILICA CARRIER FOR THE OXIDATIVE COUPLING OF METHANE AND ITS PREPARATION

摘要

The invention relates to a catalyst composition comprising manganese, one or more alkali metals, and optionally another transition metal supported on an ordered mesoporous silica carrier with ordered mesoporous structure which is maintained upon calcination; and a process for the oxidative coupling of methane using said catalyst composition. The invention further relates to the in situ preparation of the above catalyst composition by combining all catalyst constituents, i.e. catalyst carrier and metals, in their precursor state in the presence of a template material.
