Abstract:
The present invention provides an improved catalytic fast pyrolysis process for increased yield of useful and desirable products. In particular, the process comprises an improved catalytic fast pyrolysis process for producing aromatic compounds, such as, for example, benzene, toluene and xylenes, from biomass feedstock containing impurities, such as, for example alkali and alkaline earth metal, sulfur and nitrogen components.

Claim (Index 12):
A process for treating biomass containing at least 500 ppm alkali and alkaline earth metal components to reduce alkali and alkaline earth metal content to result in a treated biomass comprising steps: 1) sizing the biomass to less than or equal to 20 cm size particles, 2) extracting and washing the sized biomass of step 1) in at least one extraction and washing cycle with an extracting and washing fluid comprising acidified water having a pH less than or equal to 2 sufficiently to reduce the content of the alkali and alkaline earth metals by at least 90%, including a mass ratio of extraction and washing fluid to biomass of at least 3, 3) rinsing the washed biomass of step 2) with rinsing fluid comprising water which comprises less than or equal to 5 ppm K or less than or equal to 20 ppm Ca, or both, 4) drying the biomass of step 3) to reduce the water content to less than or equal to 10%, and optionally 5) sizing the dried biomass to less than or equal to 1 cm.
