Process for preparing organic fuels and chemicals from biomass
An integrated process is described for converting fermentable sugar in aqueous solution to gasoline boiling range products which comprises: (a) converting fermentable sugar present in an aqueous solution thereof under the action of an ethanol producing microorganism to provide a dilute aqueous solution of ethanol with the ethanol being present in the solution at a concentration which does not exceed a predetermined maximum level, the predetermined maximum level of ethanol being selected to be that which is below the level of ethanol causing fermentation to substantially cease; (b) selectively sorbing in a sorption zone, ethanol present in the solution, within a crystalline aluminosilicate zeolite characterized by a silica to alumina ratio greater than 12 and a constraint index within the range of 1 to 12, to yield an ethanol-containing zeolite, (c) exposing the resulting ethanol-containing zeolite to ethanol conversion conditions including temperatures ranging from about 316 to 538/sup 0/C, pressures ranging from about 10.13 to 1013 kPa and a liquid hourly space velocity ranging from about 0.1 to 10.
