Abstract:
A renewable fuel may be obtained from a bio-oil containing C3-C5 oxygenates. In a first step, the bio-oil is subjected to a condensation reaction in which the oxygenates undergo a carbon-carbon bond forming reaction to produce a stream containing C6+ oxygenates. In a second step, the stream is hydrotreated to produce C6+ hydrocarbons.
Abstract:
Disclosed is an alternative fuel composition derived from the conversion of biomass at an elevated temperature, with conversion optionally in the presence of a catalyst, which is capable of reducing, and thereby improving, a low temperature property of a distillate. A process is also disclosed for mixing such renewable composition with the distillate.
Abstract:
Disclosed is a process for the alteration of the ratio of the specific gravities of the oil and water phases resulting from the conversion of biomass to liquid products, the reduction of the conductivity and of metals of the product mixture, which each can aid in the removal of solids contained in the oil phase.
