Abstract: The invention is a fuel and a method for producing an improved hydrocarbon fuel for internal combustion engines and turbines. The method includes the steps of subjecting a conventional hydrocarbon liquid fuel to ozonization. The ozonization is performed under one of two conditions. The first of the two conditions is a process of forming a current of the liquid fuel and bubbling an ozone-oxygen mixture in a countercurrent through the liquid fuel. The second of the two conditions is a process of enriching the liquid fuel with oxygen and subjecting the enriched fuel with ultraviolet radiation. Desirable concentrations of ozonization products in the fuel are from 0.1% o to 2.0% o.

Abstract: A process combination is disclosed to reduce the aromatics content of a key component of gasoline blends. Paraffins contained in catalytic reformates are conserved and upgraded by separation and isomerization, reducing the reforming severity required to achieve a given product octane with concomitant reduction in paraffin aromatization and cracking. Light reformate may be separated and isomerized, and heavier paraffins are separated from the reformate by solvent extraction or adsorption; the recovered heavy paraffins are isomerized, optionally at a substoichiometric hydrogen ratio. A gasoline component having a reduced aromatics content relative to reformate of the same octane number is blended from the net products of the separation and isomerization steps.

Abstract: Internal combustion engine liquid fuels are produced by the mixing of a natural gasoline component and at least one octane-enhancing component. The mix is weathered during the blending operation to remove light-weight hydrocarbons comprising one- to four-carbon components. The light-weight hydrocarbons, which preferably constitute less than 3 percent of the blended fuel, can be recovered to generate power to run the process. The liquid fuel mixture is formulated to produce a desired octane rating, an environmentally acceptable vapor pressure, and a mix which, when burned in an internal combustion engine, produces a minimum amount of pollutants.

Abstract: An integrated process is disclosed that substantially reduces the cost of producing MTBE and other alkyl tertalkyl ethers by eliminating a major portion of the equipment and operating costs associated with the downstream processing of the etherification reactor effluent. The integrated process combines the process for the etherification of iso-olefins and methanol, or other alkanols, to produce methyl tertiary alkyl ethers such as MTBE and/or TAME with the catalytic process for converting feedstock such as oxygenates, light olefins and paraffins to higher molecular weight hydrocarbons. Unconverted reactants from the etherification reaction, which may comprise unreacted alkanol and unreacted hydrocarbons or just unreacted hydrocarbons, are separated from the product ethers and passed to the catalytic conversion process reactor for conversion to gasoline boiling range hydrocarbons.

Abstract: A process is disclosed for the isomerization of a C.sub.4 feedstock and a C.sub.5 -C.sub.6 feedstock that reduces equipment and operating expenses by utilizing a process flow scheme that provides beneficial heat integration and facilitates the use of a common recovery zone while permitting a wide variation in the relative ratio of a C.sub.4 to a C.sub.5 -C.sub.6 feedstock. The isomerization of the C.sub.4 feedstock takes place in a separate reaction zone. The effluent from the C.sub.4 isomerization zone is heat exchanged against or mixed with the C.sub.5 -C.sub.6 feedstock ahead of an additional isomerization zone that converts the C.sub.5 -C.sub.6 hydrocarbons, and if present, normal C.sub.4 hydrocarbons, to more highly branched hydrocarbons. Effluents from both isomerization zones enter a common separation section that removes light gases from the isomerate product.This invention simplifies the simultaneous isomerization of C.sub.4 and C.sub.5 -C.sub.6 feedstocks. If offers significant cost and operational advantages to newly designed units and is beneficial in the revamp of existing isomerization units to either add or improve butane isomerization capabilities. For example, butane isomerization capability may be incorporated into an existing C.sub.5 -C.sub.6 isomerization unit by adding as few pieces of major equipment as a butane drier, a feed exchanger, and one or two reactors.

Abstract: A process for upgrading of unstable olefins, naphthas, and dienes, such as coker naphthas, is disclosed. The olefins in the unstable naphthas are oligomerized over a shape selective zeolite to gasoline and distillate products. The dienes are catalytically converted by the same zeolite. Preferably, hydrogen is added to increase catalyst life. Feed pretreatment, to remove basic nitrogen compounds also improves catalyst life. Water washing of coker naphtha is the preferred method of removing basic nitrogen compounds.
