ETHANOL TO FUELS IN A CATALYTIC CRACKING UNIT STRIPPER

摘要

Processes relating to the conversion of ethanol in a stripper unit of a fluidized catalytic cracking system. An ethanol stream mixes with a catalyst in the stripper unit under conditions of temperature that favor conversion of the ethanol to hydrocarbons, thereby increasing incorporation of ethanol into liquid transportation fuels without exceeding regulatory limits on fuel vapor pressure. Certain embodiments combine the ethanol stream with a hydrocarbon stream and react in the presence of a catalyst in a stripper to produce hydrocarbons that may have an increased boiling point, increased octane rating, decreased vapor pressure, decreased benzene content, or combinations thereof.

主权项

1. A process for converting ethanol to liquid transportation fuels, the process comprising mixing and reacting a catalyst with an ethanol stream within a stripper unit of a fluidized catalytic cracking unit to produce a mixed product stream comprising hydrocarbons, wherein the ethanol stream comprises water that is converted to steam within the stripper unit.
