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 1):
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 treated biomass comprising steps 1) sizing the biomass to \u226420 cm size particles, 2) washing the sized biomass of step 1) in at least one washing cycle with a washing fluid comprising acidified water having a pH at least 2 sufficiently to reduce the content of alkali and alkaline earth metals by at least 90%, including a mass ratio of washing fluid to biomass of at least 3, 3) rinsing the washed biomass of step 2) with rinsing fluid comprising water which comprises \u22645 ppm K or \u226420 ppm Ca, or both, 4) drying the rinsed biomass of step 3) to reduce water content, and optionally 5) sizing the dried biomass to \u22641 cm.
