Abstract:
A process of methane catalytic conversion produces olefins, aromatics, and hydrogen under oxygen-free, continuous flowing conditions. Such a process has little coke deposition and realizes atom-economic conversion. Under the conditions encountered in a fixed bed reactor (i.e. reaction temperature: 750-1200° C.; reaction pressure: atmospheric pressure; the weight hourly space velocity of feed gas: 1000-30000 ml/g/h; and fixed bed), conversion of methane is 8-50%. The selectivity of olefins is 30-90%. And selectivity of aromatics is 10-70%. The catalyst for this methane conversion has a SiO 2 -based matrix having active species that are formed by confining dopant metal atoms in the lattice of the matrix.

Claim (Index 16):
The method according to  claim 13 , wherein the methane feedstock comprises methane, optionally an inert gas, optionally a non-inert gas, and is substantially oxygen free,\n wherein the inert gases is selected from a group consisting of nitrogen (N 2 ), helium (He), neon (Ne), argon (Ar), krypton (Ke), and a mixture thereof, wherein the non-inert gases is selected from a group consisting carbon monoxide (CO), hydrogen (H 2 ), carbon dioxide (CO 2 ), water vapor (H 2 O), monohydric alcohol with 1 to 5 carbon atoms, dihydric alcohol with 2 to 5 carbon atoms, alkanes with 2 to 8 carbon atoms, and a mixture thereof, and wherein the methane feedstock comprises 5-100% of methane by volume, 0-95% of the inert gas by volume, and 0-15% of the non-inert gas by volume.
