A process is provided for the conversion of carbohydrates such as starch, cellulose and sugar into hydrocarbon products of increased carbon content. Solutions of the carbohydrate are contacted with a crystalline silicate zeolite catalyst such as ZSM-5 at a temperature 300°C. to 650°C. to provide hydrocarbon products which are useful as chemicals or fuels.

A process for the conversion of carbohydrates to hydrocarbons which comprises contacting an aqueous homogeneous saturated solution of carbohydrates in a lower monohydric alcohol having a water to carbohydrate weight ratio (wt./wt.) of at least 0.3 under conversion conditions at temperatures of about 300°C. to 650°C., space velocities of 0.2 to 5.0 WHSV and pressures of 1 to 50 atmospheres absolute with a crystalline silicate zeolite catalyst having a constraint index of about 1 to 12 and a dried crystal density in the hydrogen form not substantially less than about 1.6 grams per cubic centimeter, and thereafter recovering a hydrocarbon product of increased carbon content.
