摘要:
A process for controlling a yield of an isomerization zone. Prior to entering the isomerization zone, C6 cyclic hydrocarbons are removed from a feed stream. Disproportionation reaction selectivity is observed which produces valuable C3 hydrocarbons and C4 hydrocarbons. Also, a higher ring opening conversion of C5 cyclic hydrocarbons is observed. The disproportionation reactions and the ring opening reactions may be selectively controlled by adjusting an amount of C6 cyclic hydrocarbons passed into the isomerization zone.
摘要:
Processes of and systems for removing free bromine from gaseous anhydrous HBr contaminated with free bromine are described. In one type of process the gaseous contaminated HBr is fed into countercurrent contact with at least one liquid alkylaromatic hydrocarbon within a packed section of a column while maintaining the packed section under free radical bromination conditions so that one or more than one liquid a- bromoalkylaromatic compound is produced along with one mole of gaseous HBr per mole of a- bromoalkylaromatic compound produced. In another type of process the gaseous anhydrous HBr is fed into countercurrent contact through at least two scrubbers so that the gaseous anhydrous HBr is scrubbed substantially free of bromine by passage through these at least two scrubbers, each of which contains a different specified type of scrubbing liquid. In one embodiment the liquid alkylaromatic hydrocarbon comprises 1,2-diphenylethane.
摘要:
A process for making diesel and turbine fuels includes providing an amount of one or more branched olefins and adding active heterogeneous acid catalyst(s) to the branched olefins to produce a mixture, which can be solvent-free. The process further includes heating the solvent-free mixture to a temperature greater than about 80°C for a sufficient time to produce a dimers/catalyst mixture, removing the catalysts from the dimers/catalyst mixture, and adding hydrogenation catalyst(s) to the dimers under hydrogen atmosphere to produce a mixture of stable fuels.
摘要:
Mixed alcohols are produced from syngas. The syngas (100) is provided to a catalyst (84) in a reactor (80) at selected temperatures and pressures. Reactive products, including mixed alcohols, are removed from the reactor. Non-reactive components (255,270) are removed from the mixed alcohols of their reaction products. At least part of the non- reactive components are reintroduced in the reactor along with syngas. The non-reactive components are a solvent or a super critical fluid. The non-reactive components can be reintroduced into the reactor with reactive components such as methanol or C02.
摘要:
In a dehydrogenation process a hydrocarbon stream comprising at least one non-aromatic six-membered ring compound and at least one five-membered ring compound is contacted with a dehydrogenation catalyst produced by a method comprising treating the support with a liquid composition comprising the dehydrogenation component or a precursor thereof and at least one organic dispersant selected from an amino alcohol and an amino acid. The contacting is conducted under conditions effective to convert at least a portion of the at least one non-aromatic six-membered ring compound in the hydrocarbon stream to benzene and to convert at least a portion of the at least one five-membered ring compound in the hydrocarbon stream to paraffins.
摘要:
A process and method for making a superior lubricant or distillate fuel component by the alkylation of C 5 + olefins with isoparaffins to produce a "capped" (alkylated) olefin using an acidic chloroaluminate ionic liquid catalyst system. Preferably the catalyst system includes a Brönsted acid.
摘要:
The invention relates to a EUO structural zeolite comprising at least one element X selected from silicium and germanium and at least one element T selected from aluminium, iron, gallium, vanadium, zirconium, molybdenum, arsenic, antimony, chromium and manganese. The inventive zeolite also comprises at least one alkylquinuclidinium cation in the intracrystalline porosity thereof and has an atomic ratio N/X which is greater than 0.065, wherein N is a nitrogen element. A method for preparing said zeolite and for using it in the form of a solid acid for bituminous load conversion is also disclosed.
