标 题 :Selective upgrading of naphtha fractions by a combination of reforming and selective isoparaffin synthesis

摘要:A process combination is disclosed to selectively upgrade naphtha to obtain gasoline which is in accordance with current standards for reformulated fuels. A naphtha feedstock is fractionated to selectively direct light naphtha to isomerization or blending, a heart-cut fraction to reforming, and a heavy portion to selective isoparaffin synthesis to yield light and heavy synthesis naphtha and isobutane. The heavy portion of the synthesis naphtha is processed by reforming. Light naphtha may be isomerized, with or without recycle of low-octane components of the product. A gasoline component is blended from light, synthesis, and reformate products from the process combination.

摘要:A process combination is disclosed to selectively upgrade naphtha to obtain gasoline which is in accordance with current standards for reformulated fuels. A naphtha feedstock is fractionated to selectively direct light naphtha to isomerization or blending, a head-cut fraction to reforming, and a heavy potion to selective isoparaffin synthesis to yield light and heavy synthesis naphtha and isobutane. The heavy potion of the synthesis naphtha is processed by reforming. Light naphtha may be isomerized, with or without recycle of low-octane components of the product. A gasoline component is blended from light, synthesis, and reformate products from the process combination.

摘要:A process combination is disclosed to selectively upgrade catalytically cracked gasoline to obtain products suitable for further upgrading to reformulated fuels. A naphtha feedstock, preferably heavy naphtha, is hydrogenated to saturate aromatics, followed by selective isoparaffin synthesis to yield light and heavy synthesis naphtha and isobutane. The heavy synthesis naphtha may be processed by reforming, light naphtha may be isomerized, and isobutane may be upgraded by dehydrogenation, etherification and/or alkylation to yield gasoline components from the process combination suitable for production of reformulated gasoline.

摘要:A process combination is disclosed to selectively upgrade naphtha to obtain products suitable for further upgrading to reformulated fuels. A naphtha feedstock is hydrogenated to saturate aromatics, followed by selective isoparaffin synthesis to yield light and heavy naphtha and isobutane; isobutane and isopentane in the product are obtained in superequilibrium concentrations. The heavy naphtha may be processed by reforming, light naphtha may be isomerized, and isobutane may be upgraded by dehydrogenation, etherification and/or alkylation to yield gasoline components from the process combination suitable for production of reformulated gasoline.

摘要:A reforming process, selective for the dehydrocyclization of paraffins to aromatics, is effected using a large-pore molecular-sieve catalyst containing a uniformly distributed platinum-group metal component, and a tin component incorporated into the large-pore molecular sieve by secondary synthesis. The use of this catalyst results in greater selectivity of conversion of paraffins to aromatics and in improved catalyst stability.
