Abstract: Systems and methods are provided for integration of electrolysis with biomass gasification to generate synthesis gas that can be used for production of renewable fuels and/or other hydrocarbonaceous compounds. The hydrocarbonaceous compounds can include compounds formed by chemical synthesis, such as alkanes formed by a Fischer-Tropsch process or methanol formed by a methanol synthesis process; or the hydrocarbonaceous compounds can include compounds formed by fermentation, such as alcohols formed by micro-organisms that use the synthesis gas as an input feed.

Abstract: Methods are provided for upgrading of pyrolysis carbon in order to allow for conversion of the pyrolysis carbon into higher value products. Instead of attempting to convert methane into a high value carbon product (such as carbon nanotubes) and H2 in a single reaction step, pyrolysis conditions can be used to form H2 and pyrolysis carbon. The pyrolysis carbon can then be treated in order to convert the pyrolysis carbon (H to C atomic ratio of less than 0.20) into a product with a higher hydrogen content (H to C atomic ratio of 0.25-0.9 or 2.0-7.0 wt % H). The treatment can correspond to exposing the pyrolysis carbon with hydrogen in the presence of a catalyst, exposing the pyrolysis carbon to conditions for alkylation, or a sequential combination thereof. This can convert the pyrolysis carbon into heavy hydrocarbon products that are resin-like solids at room temperature.
