Abstract
The present invention provides a process for preparing higher-value products from carbonaceous feedstocks. The process includes converting carbonaceous feedstock in a hydromethanation reactor to a methane-enriched raw product stream, converting the methane-enriched raw product stream to a methanol synthesis feed gas, then converting the methanol synthesis feed gas to higher-value products such as methanol and dimethyl ether.
