Processes for the conversion of carbohydrates to gasoline boiling range hydrocarbons, and processes for increasing the solubility of carbohydrates used in such processes are disclosed. The solubility of carbohydrates may be increased by contacting the carbohydrate with an ion-exchange resin. The dissolved product may be hydrogenated and reacted in the present of a catalyst to form a reaction product containing non-aromatic and aromatic gasoline boiling range hydrocarbons.
