Abstract:
Catalytic processes for converting carboxylic acids obtained from biomass and other natural or industrial sources into paraffinic or olefinic hydrocarbons through decarboxylation, along with products formed from such hydrocarbons, in which the carbon chain length, the ratio of carbon-14 to carbon-12, and the ratio of odd number to even number of carbons in the chain are among factors which are indicative or otherwise useful for the detection of hydrocarbons formed by undergoing the claimed processes.
Abstract:
The invention provides methods of modifying the lipids produced by microbial organisms through genetic engineering. The invention also provides genetically engineered microbes and methods of fermenting microbes for oil production. Also provided are oils, fuels, oleochemicals, chemical precursors, and other compounds manufactured by such modified microorganisms. Exemplary oil-bearing organisms include organisms containing one or more exogenous genes encoding a fatty acyl-ACP thioesterase, fatty acyl-CoA/aldehyde reductase, fatty acyl-CoA reductase, fatty aldehyde reductase, fatty aldehyde decarbonylase, and/or an acyl carrier protein.
Abstract:
A method for producing a hydrocarbon material from a C5 raffinate which is obtained as an extracted residual oil after separating at least part of the isoprene by extraction distillation from a C5 fraction which is produced as a byproduct when thermally cracking naphtha to produce ethylene and has C5 organic compounds as main ingredients comprising, a gas-phase thermal cracking step of gasifying the C5 raffinate to thermally crack at least part of the C10 diolefins which are contained in the gasified C5 raffinate, a desulfurization step, after the gas-phase thermal cracking step, of removing at least part of the sulfur-containing ingredients which are contained in the gasified C5 raffinate after the gas-phase thermal cracking step in the gas-phase state, and a hydrogen addition step, after the desulfurization step, of hydrogenating at least part of the carbon-carbon double bonds of at least one selected from diolefins and olefins which are contained in the gasified C5 raffinate after the desulfurization step in the gas-phase state, so as to obtain a hydrocarbon material with a total concentration of diolefins and olefins of 0.5 wt % or less is provided.
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:
A liquid fuel formed by the mixture of toluene, meta-xylene and n-hexane, in proportions of between 50 and 70% of toluene, between 10 and 20% of meta-xylene and between 20 and 30% of n-hexane.
Abstract:
An apparatus is disclosed. The apparatus includes a bubble implosion reactor cavitation device. The bubble implosion reactor cavitation device includes a tube-shaped cylindrical body including an upstream, a distal end surface and a downstream, proximal end surface. The tube-shaped cylindrical body defines an axial passage that extends through the tube-shaped cylindrical body between the upstream, distal end surface and the downstream, proximal end surface. The apparatus also includes a bubble generator subassembly connected to the tube-shaped cylindrical body. The bubble generator subassembly is at least partially disposed within the axial passage defined by the tube-shaped cylindrical body. The apparatus also includes a retaining member connected to the tube-shaped cylindrical body for retaining the bubble generator subassembly within the axial passage defined by the tube-shaped cylindrical body.
Abstract:
Generation of a liquid fuel product in an integrated multiple zone plant is discussed. Syngas components are supplied to a methanol (CH3OH) synthesis reactor from outputs of a first zone containing a torrefaction unit and a second zone containing a biomass gasifier that are combined in parallel and that thermally decompose biomass at different operating temperatures. Char particles of the biomass generated in the first zone are fed to the biomass gasifier in the second zone. Gasoline is produced via a methanol to gasoline process in a third zone, which receives its methanol derived from the syngas components fed to the methanol synthesis reactor. The gasoline derived from biomass is blended with condensable volatile materials including C5+ hydrocarbons collected during the pyrolyzation of the biomass in the torrefaction unit in the first zone in order to increase an octane rating of the blended gasoline.
Abstract:
A process of modifying a zeolite catalyst to produce a modified zeolite catalyst wherein the modified zeolite catalyst has blocked pore sites. An oxygenated feed is flowed over the modified zeolite catalyst, wherein the oxygenated feed comprises hydrocarbons, methanol and dimethyl ether or a mixture thereof. The hydrocarbons, methanol and dimethyl ether in the oxygenated feed react with the modified zeolite catalyst to produce cyclic hydrocarbons, wherein the cyclic hydrocarbons produced has less than 10% durene and a median carbon number is C8.
Abstract:
The present invention generally relates to a method for producing a naphtha product from a renewable feedstock. The method includes hydrotreating the renewable feedstock to produce a hydrotreating unit heavy fraction that includes n-paraffins, and hydrocracking the hydrotreating unit heavy fraction to produce a hydrocracking unit product that includes the naphtha product. The method also includes separating the naphtha fraction and optionally recycling the hydrocracking unit heavy fraction through the hydrocracking unit. The present invention also relates to a biorenewable naphtha product suitable for use as feed stock for steam crackers and catalytic reforming units, and for use as fuel, or fuel blend stock.
