Patent ID: 8617262

Claim:
A process comprising the steps of: (a) providing a biomass-derived feedstream comprising light glycols, wherein said glycols comprise molecules containing two, three or four carbon atoms; (b) contacting the feedstream of step (a) with a first catalyst in a reactor, wherein the contacting results in an acidic condensation reaction that converts a least a portion of the feedstream to condensation products, wherein said condensation products comprise at least 4 carbon atoms at least one ether functional group, and one or more remaining hydroxyl functional groups; (c) converting at least a portion of the remaining hydroxyl functional groups on the condensation products from step (b) to ether functional groups by combining the condensation products with a second catalyst to produce a liquid hydrocarbon mixture suitable for use as an additive to liquid hydrocarbon fuels, wherein the converting takes place in the presence of an olefin, monofunctional alcohol or mixtures thereof, wherein the liquid hydrocarbon mixture has increased miscibility in liquid hydrocarbon fuels as a result of step c).
