摘要:
A bio-oil product is produced from biomass material by subjecting the biomass material to a first stage liquefaction process, where the first stage liquefaction process includes combining the biomass material with a co-solvent including methanol and water to form a first slurry mixture, providing the slurry mixture within a first liquefaction reactor and maintaining the first slurry mixture at a sufficient temperature and pressure so as to convert a portion of the biomass material into a first liquefied bio-oil product as well as form a first aqueous product and a first solid product, and separating the first liquefied bio-oil product from the aqueous and solid products. The solid product obtained from the first stage liquefaction process is subjected to a second stage liquefaction process, where the second stage liquefaction process includes combining the first solid product with methane to form a second slurry mixture, and providing the second slurry mixture within a second liquefaction reactor and maintaining the second slurry mixture at a sufficient temperature and pressure so as to convert a portion of the first solid product to a second liquefied bio-oil product as well as form a second aqueous product and a second solid product.

Systems and methods are provided for the conversion of methanol to gasoline. Such methods may be performed be the sequential conversion of methanol to dimethyl ether, the conversion of dimethyl ether (and unconverted methanol, if present) to an intermediate olefin-rich product, and the oligomerization of the olefin-rich product to gasoline boiling range hydrocarbons.
