An integrated plant is provided to improve carbon utilization of carbon molecules from gasified woody biomass to be converted into methanol. Detectors ensure a minimized sulfur content of less than 0.05% by dry weight of the woody biomass. A biomass gasifier reacts woody biomass in a rapid gasification reaction to produce a syngas composition having a ratio of hydrogen to carbon dioxide that is higher than needed for methanol synthesis. Parallel to the gasifier, a hydrocarbon reforming reactor provides a syngas composition having a ratio of hydrogen to carbon monoxide that is higher than needed for methanol synthesis. The combined syngas mixture from the biomass gasifier and the hydrocarbon reforming reactor comprises feed to a methanol synthesis plant, such that a majority of the carbon dioxide produced by the biomass gasification reaction and the hydrogen produced by the hydrocarbon reforming reactor are synthesized into methanol. |
