Abstract: An integrated system for the conversion of biomass to renewable natural gas and then to methanol and other value-added products is provided. The integrated system includes a compressor that receives biomass gases from a biomass source and a series of purification stations that produce purified gas from the biomass gases. Characteristically, the purified gas has an enhanced amount of methane. A gas-to-liquids plant converts the purified gas to a product blend that includes methanol.

Abstract: A reactor (12) and method for the conversion of hydrocarbons utilizes a reactor (12) having a unique feed assembly (56) that creates an inwardly spiraling fluid flow pattern of the feed gases to form a swirling gas mixture that passes through a conduit (46) with a constricted neck portion or nozzle (52). At least a portion of the swirling gas mixture forms a thin, annular mixed gas flow layer immediately adjacent to the conduit (46). A portion of the swirling gas mixture is combusted as the swirling gas mixture passes through the conduit (46) for conversion of hydrocarbons.
