PROCESSO PARA PRODUZIR COMBUSTIVEIS HIDROCARBONETOS LIQUIDOS,LIVRES DE COMPOSTOS OXIGENADOS,A PARTIR DE BIOMASSA

摘要

A continuous thermochemical indirect liquefaction process to convert various biomass materials into diesel-type transportation fuels which fuels are compatible with current engine designs and distribution systems comprising feeding said biomass into a circulating solid fluidized bed gasification system to produce a synthesis gas containing olefins, hydrogen and carbon monoxide and thereafter introducing the synthesis gas into a catalytic liquefaction system to convert the synthesis gas into liquid hydrocarbon fuel consisting essentially of C7-C17 paraffinic hydrocarbons having cetane indices of 50+.
