Process for converting biomass to hydrocarbons and oxygenates

摘要

A process for converting biomass to hydrocarbons and oxygenates that may include providing a biomass feedstock and de-oxygenating the biomass feedstock to form a solid-intermediate. The process may further include liquefaction of the solid intermediate, which may be carried out either by rapid heating followed by condensation or by liquefying by applying high pressure. The liquefaction of the solid intermediate may produce a mixture of hydrocarbons and oxygenates, which is generally termed as biocrude. Further, the biocrude is processed by one or more refining means for production of hydrocarbons that can be used as fuel.

1. A process for processing biomass to hydrocarbons and oxygenates, the process comprising:
a. providing a biomass feedstock; b. de-oxygenating the biomass feedstock to form a solid-intermediate in a gaseous atmosphere containing a component selected from the group consisting of nitrogen, hydrogen, carbon monoxide, methane, ethane, propane, butane, pentane and any combination thereof; c. liquefying the solid-intermediate to produce a biocrude; and d. processing said biocrude by one or more refining means to produce one or more hydrocarbons.
