Abstract: Isobutanol may be converted into predominantly C12+ olefin oligomers under specified conditions. Such methods may comprise: contacting a feed comprising isobutanol with a zeolite solid acid catalyst having a MWW framework under conditions effective to convert the isobutanol into a product comprising C4n olefin oligomers, wherein n is an integer having a value of two or greater and about 80 wt. % or greater of the C4n olefin oligomers are larger than C8.

Abstract: The present disclosure relates to processes for producing hydrocarbon fuels from lignocellulosic biomass. A process may include introducing biomass to a pretreatment system forming a pretreatment effluent and introducing the pretreatment effluent to a hydrolysis system forming a hydrolysate. The hydrolysate may be introduced to a lignin separation system to form a sugar-rich stream and a lignin-rich stream. The sugar-rich stream may be introduced to a purification system comprising at least one toxin converting microorganism or subcellular material to form a purified sugar-rich stream, and the purified sugar-rich stream and one or more sugar converting microorganisms are introduced to a bioreactor configured to produce hydrocarbon fuels. Additionally, the present disclosure also related to systems for production of hydrocarbon fuels including, a pretreatment system, a hydrolysis system, a lignin separation system, a purification system, and at least one bioreactor.

Abstract: The present disclosure relates to processes for producing hydrocarbon fuels from lignocellulosic biomass. A process may include introducing biomass to a pretreatment system, and a first separation system forming a pentose-rich stream and a pentose-lean stream. The pentose-lean stream may be introduced to a hydrolysis system forming a hydrolysate and the hydrolysate introduced to a second separation system forming a hexose-rich stream and a lignin stream. Additionally, at least one of the pentose-rich stream or the hexose-rich stream may be introduced to a bioreactor containing microorganisms configured to produce hydrocarbon fuels. Additionally, the present disclosure also relates to systems for the production of hydrocarbon fuels. A system may include a pretreatment system, a first separation system, a hydrolysis system, a second separation system, and one or more bioreactors. Alternatively a system may include a pretreatment system, a hydrolysis system, a sugar separation system, and one or more bioreactors.

Abstract: Systems and methods are provided for integrated conversion of biomass to ultimately form naphtha and/or diesel boiling range products. The integrated conversion can include an initial conversion of biomass to alcohols, such as by fermentation, followed by conversion of alcohols to olefins and then olefins to naphtha, jet, and diesel boiling range compounds, with high selectivity for formation of diesel boiling range compounds. The integrated conversion process can be facilitated by using a common catalyst for both the conversion of alcohols to olefins and the conversion of olefins to naphtha and/or diesel boiling range compounds. For example, ZSM-48 (an MRE zeotype framework structure catalyst) can be used as the catalyst for both conversion of alcohols to olefins and for oligomerization of olefins with increased selectivity for formation of diesel boiling range products.

Abstract: Systems and methods are provided for conversion of oxygenate feeds to distillate boiling range products using multiple moving bed reactor stages. The systems and methods allow for multiple stages to be used while avoiding the need for distillation or other boiling point based separation as the mixture of feed and effluent is passed between stages. Instead, a stripping gas is used to disengage the feed and effluent from the catalyst solids. In combination with an improved moving bed reactor design, this can allow substantially all of the feed and effluent from a first moving bed reactor stage to be passed into a second moving bed reactor stage, even when the feed and effluent include both vapor and liquid phase portions.
