Premium synthetic lubricant base stock having at least 95% non-cyclic isoparaffins
InactiveUS6080301ARefining to change hydrocarbon structural skeletonHydrocarbon purification/separationParaffin waxAlkane
A premium synthetic lubricating oil base stock having a high VI and low pour point is made by hydroisomerizing a Fischer-Tropsch synthesized waxy, paraffinic feed wax and then dewaxing the hydroisomerate to form a 650-750 DEG F.+ dewaxate. The waxy feed has an initial boiling point in the range of about 650-750 DEG F., from which it continuously boils up to at least 1050 DEG F. and has a T90-T10 temperature difference of at least 350 DEG F. The feed is preferably hydroisomerized without any pretreatment, other than optional fractionation. The 650-750 DEG F.+ dewaxate is fractionated into two or more base stocks of different viscosity.

InactiveUS6103099AThermal non-catalytic crackingRefining to change hydrocarbon structural skeletonAutomatic transmissionBoiling point
A lubricating base stock useful for forming lubricants such as a multigrade automotive oils, automatic transmission oils, greases and the like is prepared by hydroisomerizing a waxy hydrocarbon feed fraction having an initial boiling point in the 650-750 DEG F. range and an end point of at least 1050 DEG F., synthesized by a slurry Fischer-Tropsch hydrocarbon synthesis process.

Catalytic multi-stage process for hydroconversion and refining hydrocarbon feeds
InactiveUS6190542B1Improve distillation yieldQuality improvementCatalyst activation/preparationLiquid hydrocarbon mixture productionLiquid productDistillates petroleum
A multi-stage catalytic hydrogenation and hydroconversion process for heavy hydrocarbon feed materials such as coal, heavy petroleum fractions, and plastic waste materials. In the process, the feedstock is reacted in a first-stage, back-mixed catalytic reactor with a highly dispersed iron-based catalyst having a powder, gel or liquid form. The reactor effluent is pressure-reduced, vapors and light distillate fractions are removed overhead, and the heavier liquid fraction is fed to a second stage back-mixed catalytic reactor. The first and second stage catalytic reactors are operated at 700-850.degree. F. temperature, 1000-3500 psig hydrogen partial pressure and 20-80 lb. / hr per ft.sup.3 reactor space velocity. The vapor and light distillates liquid fractions removed from both the first and second stage reactor effluent streams are combined and passed to an in-line, fixed-bed catalytic hydrotreater for heteroatom removal and for producing high quality naphtha and mid-distillate or a full-range distillate product. The remaining separator bottoms liquid fractions are distilled at successive atmospheric and vacuum pressures, low and intermediate-boiling hydrocarbon liquid products are withdrawn, and heavier distillate fractions are recycled and further upgraded to provide additional low-boiling hydrocarbon liquid products. This catalytic multistage hydrogenation process provides improved flexibility for hydroprocessing the various carbonaceous feedstocks and adjusting to desired product structures and for improved economy of operations.

This invention relates to compositions and methods for fluid hydrocarbon product, and more specifically, to compositions and methods for fluid hydrocarbon product via catalytic pyrolysis. Some embodiments relate to methods for the production of specific aromatic products (e.g., benzene, toluene, naphthalene, xylene, etc.) via catalytic pyrolysis. Some such methods may involve the use of a composition comprising a mixture of a solid hydrocarbonaceous material and a heterogeneous pyrolytic catalyst component. In some embodiments, the mixture may be pyrolyzed at high temperatures (e.g., between 500° C. and 1000° C.). The pyrolysis may be conducted for an amount of time at least partially sufficient for production of discrete, identifiable biofuel compounds. Some embodiments involve heating the mixture of catalyst and hydrocarbonaceous material at high rates (e.g., from about 50° C. per second to about 1000° C. per second). The methods described herein may also involve the use of specialized catalysts. For example, in some cases, zeolite catalysts may be used; optionally, the catalysts used herein may have high silica to alumina molar ratios. In some instances, the composition fed to the pyrolysis reactor may have a relatively high catalyst to hydrocarbonaceous material mass ratio (e.g., from about 5:1 to about 20:1).

Apparatus for converting coal to hydrocarbons
InactiveUS6013158ALess producedLow costCombustible gas coke oven heatingDirect heating destructive distillationParticulatesSuspended particles
An apparatus for forming liquid hydrocarbons from solid coal. The coal is pulverized to provide a particulate coal feed, which is then extruded to provide a hollow tube of compressed coal supported inside of a support tube. A clay feed is extruded to provide a hollow tube of compressed clay supported inside of the coal tube and a combustible fuel is burned inside of the clay tube. The temperature of combustion is sufficient to fire the extruded clay and pyrolyze the extruded coal to produce hydrocarbon gases and coal char. The support tube has holes for releasing the hydrocarbon gases, which contain suspended particles formed during combustion. The suspended particles are removed from the hydrocarbon gases to provide clean gases, which are passed through an ionizing chamber to ionize at least a portion thereof. The ionized gases are then passed through a magnetic field to separate them from each other according to their molecular weight. Selected portions of at least some of the separated gases are mixed, and the mixed gases are cooled to provide at least one liquid hydrocarbon product of predetermined composition. Portions of the separated gases may also be mixed with the coal char and other input streams, such as waste plastics, and further treated to provide other hydrocarbon products.

InactiveUS20080050792A1Increase productionAcceptable processing conditionBiofuelsSolid fuelsLiquid productLignin degradation
Processes for conversion of lignin to liquid products such as bio-fuels and fuel additives are disclosed and described. A process for conversion of a lignin material to bio-fuels can include subjecting the lignin material to a base catalyzed depolymerization reaction to produce a partially depolymerized lignin. The partially depolymerized lignin can then be subjected to a stabilization / partial hydrodeoxygenation reaction to form a partially hydrodeoxygenated product. Following partial hydrodeoxygenation, the partially hydrodeoxygenated product can be reacted in a hydroprocessing step to form a bio-fuel. Each of these reaction steps can be performed in single or multiple steps, depending on the design of the process. The production of an intermediate partially hydrodeoxygenation product and subsequent reaction thereof can significantly reduce or eliminate reactor plugging and catalyst coking. A variety of useful bio-fuels such as fuels, fuel additives, and the like, including gasoline and jet or rocket fuels are describe which can be readily produced from renewable lignin materials in an improved conversion process.
