Abstract
A method for forming a desired hydrocarbon fuel product from a mixed oxygenate feedstock by utilizing chemical processes to form ketones from the oxygenate feed, upgrade the ketones, recycle selected upgraded ketones through the upgrading process to obtain a desired intermediate and hydrogenating the desired intermediate to obtain the desired hydrocarbon fuel product. In various alternative configurations and embodiments this can be accomplished in a number of ways, and originate in a number of different positions and occasions.
Claims14
A method for forming a desired hydrocarbon fuel product from a mixed oxygenate feed comprising the steps of:
- forming ketones from the mixed oxygenate feedstock by passing the mixed oxygenate feedstock over a preselected catalyst under preselected conditions;
- upgrading the ketones by reacting the ketones under preselected conditions;
- recycling selected upgraded ketones through the upgrading process to obtain a branched cyclohexenone product;
- and
- hydrogenating the branched cyclohexenone product to obtain the desired hydrocarbon fuel product.
