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.

Abstract: The present invention relates to processes for hydromethanating a carbonaceous feedstock to a methane product stream and electrical power, in which heat energy from the hot methane-enriched synthesis gas is used to generate a dry saturated steam stream, the dry saturated steam stream is converted into a superheated steam stream via pressure drop for feeding into the hydromethanation reactor to satisfy the steam demand of the hydromethanation reaction, and heat generated from a downstream gas methanation processing is recovered to produce a superheated process steam stream which is used to generate the electric power.

Abstract: Systems to convert a carbonaceous feedstock into a plurality of gaseous products are described. The systems include, among other units, four separate gasification reactors for the gasification of a carbonaceous feedstock in the presence of an alkali metal catalyst into the plurality of gaseous products including at least methane. Each of the gasification reactors may be supplied with the feedstock from a single or separate catalyst loading and/or feedstock preparation unit operations. Similarly, the hot gas streams from each gasification reactor may be purified via their combination at a heat exchanger, acid gas removal, or methane removal unit operations. Product purification may comprise trace contaminant removal units, ammonia removal and recovery units, and sour shift units.
