摘要： An improved process for upgrading paraffinic naphtha to high octane fuel by contacting a naphtha feedstock, such as virgin naphtha feedstock stream containing predominantly C.sub.7 -C.sub.12 alkanes and naphthenes, with solid medium pore acid zeolite cracking catalyst under low pressure selective cracking conditions effective to produce at least 10 wt % selectivity C.sub.4 -C.sub.5 isoalkene. Cracking effluent is separated to obtain a light olefinic fraction rich in C.sub.4 -C.sub.5 isoalkene and a C.sub.6 + liquid fraction of enhanced octane value containing less than 50 wt % aromatic hydrocarbons. In a multistage operation enhanced octane products are obtained by etherifying the isoalkene fraction and by contacting the C.sub.6 + normally liquid fraction with reforming catalyst under moderate reforming conditions at elevated temperature to obtain a reformate product of enhanced octane value.

摘要： A method is disclosed for the pretreatment of olefinic hydrocarbon feedstock to remove conjugated dienes and/or basic nitrogen compounds that deactivate acidic catalyst particles used in olefin conversion processes by reacting the dienes with one or more dienophiles to form the corresponding Diels-Alder adduct, followed by catalytic conversion of the olefinic hydrocarbon feedstock containing the adduct. The formation of the Diels-Alder adduct essentially eliminates the role of dienes in the feedstock as catalyst deactivating agents. When maleic anhydride (MA) is employed as the dienophile, basic nitrogen reacts with maleic anhydride, or with the tetrahydrophthalic anhydride adduct, to lower the amount of catalyst deactivating basic nitrogen compounds in the feedstock. Where the olefin conversion process comprises etherification of isoolefins with alkanol in a C.sub.4 + or C.sub.5 + olefinic hydrocarbon feedstream to produce a gasoline boiling range product enriched in oxygen and rich in high octane value alkyl tertiary alkyl ethers, it has been discovered that the adduct, particularly those adducts formed with MA, is in the gasoline boiling range and contributes usefully to the oxygen enrichment of the gasoline and to octane value.

摘要： A selective alkene upgrading process wherein a mixture of intermediate molecular weight monoalkenes comprising at least one linear alkene component and at least one tertiary alkene component is contacted under selective olefin interconversion conditions with medium pore, shape selective acid catalyst, such as MCM-22 aluminosilicate zeolite, thereby converting at a major amount of linear intermediate alkene to lower alkene while leaving tertiary alkene substantially unconverted. In the preferred embodiments, the process interconversion conditions comprise reaction temperature in the range of about 300.degree. C. to 550.degree. C., pressure in the range of 100 kpa to 1000 kPa, thereby selectively converting at least 60% (net) of linear intermediate alkene while converting less than 20% (net) of branched alkene. By etherifying at least a portion of the unconverted tertiary alkene, an oxygenated fuel having enhanced octane rating is obtained. Cracked lower olefins may be recovered for upgrading.

摘要： A process for upgrading olefinic feedstocks containing lower olefins employing new synthetic catalyst of ultra-large pore crystalline material. The new crystalline material exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams at 50 torr and 25.degree. C., a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 Angstrom Units and a hexagonal arrangement of uniformly sized pores with a maximum perpendicular cross section of at least about 13 Angstrom units. A multistage process is provided for catalytic oligomerization of lower olefin which comprises contacting olefinic feedstock under catalytic conversion conditions with acid metallosilicate solid catalyst having the structure of MCM-41 with hexagonal honeycomb lattice structure consisting essentially of uniform pores in the range of about 20 to 100 Angstroms. The oligomerization reaction is very selective, especially when conducted at temperature of about 40.degree. to 250.degree. C., yielding branched intermediate olefins. Low severity reaction permits excellent conversio of lower olefins at pressure of about 100-13,000 pKa range and moderate space velocity. Intermediate oligomers produced over MCM-41, when reacted under cracking/disproportionation conditions yield etherifiable C.sub.4 + isoalkenese in good yield.

摘要： There is provided a sulfated layered titanium oxide catalyst. Relatively long chain alkyl aromatic compounds are prepared by alkylating an alkylatable aromatic compound with a relatively long chain alkylating agent under alkylation reaction conditions in the presence of this sulfated layered material as alkylation catalyst. The layered material contains titanium oxide in the layers and oxide pillars separating the layers. The alkylation activity of the catalyst is increased by including sulfate ions in the layered material. This increased alkylation activity may be obtained by contacting the layered material with an aqueous solution of a sulfate compound such as sulfuric acid.
