Abstract
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.
Claims67
A process comprising:
- contacting a carbohydrate-containing material with an ion-exchange resin in a liquid medium to form a mixture;
- heating said mixture at a temperature sufficient to substantially dissolve said carbohydrate-containing material in said liquid medium;
- and
- contacting said mixture with a hydrogenation catalyst under a condition sufficient to form a hydrogenated product.
A process comprising:
- contacting a carbohydrate-containing material with an ion-exchange resin in a liquid medium under a condition sufficient to substantially dissolve the carbohydrate-containing material in the liquid medium to form a mixture,
- contacting the mixture with a hydrogenation catalyst under a condition sufficient to form a hydrogenated product, and
- contacting a mixture comprising the hydrogenated product with a catalyst composition comprising a zeolite under a condition sufficient to form a reaction product containing gasoline boiling range hydrocarbons.
The process in accordance with claim l7 further comprising a step of modifying a zeolite by acid treatment prior to a step of contacting a mixture comprising the hydrogenated product with a catalyst composition comprising said zeolite.
A process comprising:
- contacting an aqueous solution containing at least one carbohydrate with a hydrogenation catalyst under a condition sufficient to form a hydrogenated product, and
- contacting the hydrogenated product with a catalyst composition comprising a zeolite under conditions sufficient to form a reaction product containing gasoline boiling range hydrocarbons.
A process comprising:
- contacting a mixture comprising a hydrogenated carbohydrate-containing compound and a hydrocarbon with a catalyst composition comprising a zeolite under a reaction conditions sufficient to form a reaction product containing gasoline boiling range hydrocarbons.
