Номер: CA0002648783C

A process for the alkylation of isobutane is disclosed wherein isobutane is fed to two separate alkylation systems. The effluent from the first alkylation system is fed to an interim debutanizer where the C4's are separated from the alkylate product. The overhead C4 product is then fed to the second alkylation system to provide the isobutane. The effluent from the second alkylation system is fed to a traditional deisobutanizer to prevent any build up of normal butanes in the system.

Conversion of residual oil to gasoline

Номер: GB0000923246A
Автор:

Heavy, residual hydrocarbons are converted to gasoline and other products by coking and recovering a gas oil fraction, treating this to reduce the nitrogen content below 10 p.p.m., and contacting together with at least 500 preferably at least 2,000 SCF of hydrogen per barrel with an acidic cracking catalyst having hydrogenating characteristics at 350-700 DEG F. and at least 400 p.s.i.g. to convert at least part to gasoline. The feed, e.g. a reduced crude, is subjected to delayed or fluidised coking. The gas oil may be recovered from the product as two fractions, a heavy and a light gas oil. The former may be subjected to conventional thermal or catalytic cracking to obtain gasoline and heavy and light cycle oils. The heavy cycle oil is used as jet fuel or recycled to the cracking while the light cycle oil is added to the light coker gas oil and the combined feed is denitrified. Alternatively a portion of the heavy gas oil may be recycled to the coking step or passed with the light gas oil ...

Embodiments of methods for the production of linear alkylbenzene and optionally biofuel from a natural oil are provided. A method comprises the step of deoxygenating the natural oils to form paraffins. A first portion of the paraffins is hydrocracked to form a first stream of normal and lightly branched paraffins in the C 9 to C 14 range and a second stream of isoparaffins. The first stream is dehydrogenated to provide mono-olefins. Then, benzene is alkylated with the mono-olefins under alkylation conditions to provide an alkylation effluent comprising alkylbenzenes and benzene. Thereafter, the alkylbenzenes are isolated to provide the alkylbenzene product. Optionally a second portion of the paraffins and the isoparaffins are processed to form biofuel.

Methods and a system for manufacturing a base stock from an ethanol stream are provided. An example method includes dehydrating an ethanol stream to form an impure ethylene stream, recovering an ethylene stream from the impure ethylene stream, and oligomerizing the ethylene stream to form a raw oligomer stream. A light olefinic stream is distilled from the raw oligomer stream and blended with the ethylene stream prior to the oligomerization. A heavy olefinic stream is distilled from the raw oligomer stream and hydro-processed to form a hydro-processed stream. The hydro-processed stream is distilled to form the base stock.

Process for heavy oil and bitumen upgrading

Номер: US9169443B2
Автор: Steve Kresnyak
Принадлежит: EXPANDER ENERGY Inc

A bitumen and heavy oil upgrading process and system is disclosed for the synthesis of hydrocarbons, an example of which is synthetic crude oil (SCO). The process advantageously avoids the waste attributed to residuum and/or petcoke formation which has a dramatic effect on the yield of hydrocarbon material generated. The process integrates Fischer-Tropsch technology with gasification and hydrogen rich gas stream generation. The hydrogen rich gas generation is conveniently effected using singly or in combination a hydrogen source, a hydrogen rich vapor from hydroprocessing and the Fischer-Tropsch process, a steam methane reformer (SMR) and autothermal reformer (ATR) or a combination of SMR/ATR. The feedstock for upgrading is distilled and the bottoms fraction is gasified and converted in a Fischer-Tropsch reactor. A resultant hydrogen lean syngas is then exposed to the hydrogen rich gas stream to optimize the formation of, for example, the synthetic crude oil. The hydrogen lean gas stream may also be effected by a water gas shift reaction, singly or in combination or in addition with the hydrogen rich gas stream generation. A system for effecting the process is also characterized in the specification.

Process for improving thermal stability of synthetic lubes

Номер: US4967032A
Принадлежит: Mobil Oil Corp

A process is disclosed for improving the thermal stability of polyalpha-olefin lubricants by contacting the lubricant with an acidic catalyst for a time and at a temperature sufficient to achieve the skeletal isomerization of the molecular structure of the lubricant. The reaction is carried out preferably on unhydrogenated synthetic lubricants in contact with Lewis acid catalysts. Following the isomerization reaction, the unsaturated lubricant is hydrogenated to produce lubricant with better thermal stability. Surprisingly, when the isomerization reaction is carried out using unsaturated oligomer produced from the oligomerization of alpha-olefins in contact with reduced Group VIB metal oxide catalyst on porous support as starting material the viscometric properties of the lubricant, e.g., viscosity and VI, are not significantly altered, although the thermal stability of the lubricant is substantially increased. The reaction of the present invention may be carried out in the presence of a solvent or neat. Improvements in thermal stability are observed over a wide range of catalyst concentration. Concentrations of about 10 weight percent are preferred with aluminum chloride catalyst.
