Abstract:
The invention provides methods of cultivating oil-bearing microbes using cellulosic material. Also provided are microorganisms containing one or more exogenous genes that facilitate the use of cellulosic materials as a feedstock. Also provided are microorganisms and methods for manufacturing non-alcohol-based fuels and fuel feedstocks through a process of converting cellulosic materials into oils.
Abstract:
Biogases such as natural gas and other gases capable of being biologically derived by digestion of organic matter are converted to a clean-burning hydrocarbon liquid fuel in a process wherein a biogas is fed to a reaction vessel where the biogas contacts a liquid petroleum fraction and a transition metal catalyst immersed in the liquid, vaporized product gas is drawn from a vapor space above the liquid level, condensed, and fed to a product vessel where condensate is separated from uncondensed gas and drawn off as the liquid product fuel. Uncondensed gas can be recycled to the reaction vessel.

The current invention provides a method for the manufacture of an ether of 5-hydroxymethylfurfural by reacting a hexose-containing starting material with an olefin in the presence of an acid catalyst
Abstract:
A process for the production of low sulfur diesel and high octane naphtha. Separate high pressure vapor liquid separators serve to maintain and isolate the high octane naphtha produced in the hydrocracking zone thereby maximizing the value of the hydrocarbon streams produced.
Abstract:
Process for converting oxygenate compounds to hydrocarbons comprising the steps: (a) introducing a feed stream of synthesis gas to a synthesis section for the production of easily convertible oxygenates, (b) passing the effluent stream from said synthesis section containing easily convertible oxygenates to a gasoline synthesis section, (c) passing the effluent of said gasoline synthesis section to a separator and withdrawing from said separator hydrocarbons boiling in the gasoline boiling range, (d) admixing a recycle stream from the separator containing unconverted synthesis gas volatile hydrocarbons with the feed stream of synthesis gas of step (a), (e) introducing a feed containing difficulty convertible oxygenates to the synthesis section of step (a).
Abstract:
Described herein are methods for cracking a biocrude, particularly catalytically cracking a biocrude that primarily includes olefmic hydrocarbons. Also described herein are compositions and methods of producing such compositions that are useful as fuels or fuel production feedstock.
Abstract:
A process is described for converting synthesis gas containing carbon monoxide and hydrogen to hydrocarbons via methanol as an intermediate, by contacting the synthesis gas with a catalyst system containing a mixture of gallium silicate zeolite catalyst and a methanol catalyst. The process results in reduced amounts of undesirable low carbon number hydrocarbons, e.g., C4 and lower, undesirable high carbon number hydrocarbons, e.g., C10 and higher, and aromatic hydrocarbons. The process provides higher yields of useful, high octane hydrocarbons boiling in the gasoline range.
Abstract:
A process for upgrading hydrocarbons comprising removal of C5 hydrocarbons from a feedstock, metathesizing said C5 hydrocarbons to C6+ and C4− hydrocarbons, and upgrading said C4− hydrocarbons is disclosed.

Abstract:
The present invention relates to a process for manufacturing neohexene, comprising contacting isobutene with a supported catalyst comprising a tungsten compound chosen from tungsten hydrides, organometallic tungsten compounds and organometallic tungsten hydrides, and a support comprising an oxide of aluminium, so as to form a reaction mixture comprising neohexene, and preferably separating neohexene from the reaction mixture, so as to isolate it. The contacting leads to the direct production of neohexene, in particular in a single (reaction) stage and with a high molar selectivity for neohexene. The contacting can be performed at a temperature of 50 to 600° C., under a total absolute pressure of 0.01 to 100 MPa.
