Multiple stages of reactors form a bio-reforming reactor that generates chemical grade bio-syngas for any of 1) a methanol synthesis reactor, 2) a Methanol-to-Gasoline reactor train, 3) a high temperature Fischer-Tropsch reactor train, and 4) any combination of these three that use the chemical grade bio-syngas derived from biomass fed into the bio-reforming reactor. A tubular chemical reactor of a second stage has inputs configured to receive chemical feedstock from at least two sources, i) the raw syngas from the reactor output of the first stage via a cyclone, and ii) purge gas containing renewable carbon-based gases that are recycled back via a recycle loop as a chemical feedstock from any of 1) the downstream methanol-synthesis-reactor train, 2) the downstream methanol-to-gasoline reactor train, or 3) purge gas from both trains. The plant produces fuel products with solely 100% biogenic carbon content as well as fuel products with 50-100% biogenic carbon content.

An improved process for the catalytic gasification of a carbonaceous feedstock in a dual fluidized bed reactor for producing synthesis gas is disclosed. The disclosure uses ?-alumina as a catalyst support i and heat carrier in the gasification zone (102). The gasification zone (102) is operated at 700-750? C. to prevent substantial conversion of ?-alumina to ?-alumina, which would manifest in the enablement of high catalyst loading and high recyclability. The catalyst is an alkali metal, preferably K.sub.2CO.sub.3, so that conversion proportional to total K.sub.2CO.sub.3 to solid carbon ratio is achieved with as high K.sub.2CO.sub.3 loading as 50 wt % on the solid support. The combustion zone (140) is operated at 800?-840? C., to prevent any conversion of the ?-alumina to ?-alumina, so that catalyst recyclability of up to 98% is achieved between two successive cycles.

A feedstock delivery system transfers a carbonaceous material, such as municipal solid waste, into a product gas generation system. The feedstock delivery system includes a splitter for splitting bulk carbonaceous material into a plurality of carbonaceous material streams. Each stream is processed using a weighing system for gauging the quantity of carbonaceous material, a densification system for forming plugs of carbonaceous material, a de-densification system for breaking up the plugs of carbonaceous material, and a gas and carbonaceous material mixing system for forming a carbonaceous material and gas mixture. A pressure of the mixing gas is reduced prior to mixing with the carbonaceous material, and the carbonaceous material to gas weight ratio is monitored. A transport assembly conveys the carbonaceous material and gas mixture to a first reactor where at least the carbonaceous material within the mixture is subject to thermochemical reactions to form the product gas.
