Abstract:
A process for the simultaneous dewaxing of high pour point gas oil and upgrading of an aromatic containing naphtha by contact of a mixture of the gas oil and naphtha with hydrogen and a high silica to alumina ratio synthetic aluminosilicate zeolite catalyst, which is derived from a zeolite which was synthesized with an organic cation, at about 500* to 1000*F followed by distillation of the product in order to recover a lower pour point gas oil fraction and a higher octane gasoline fraction.
Abstract:
A CONTINUOUS PROCESS FOR ALKYLATION OF A BRANCHED CHAIN HYDROCARBON WITH AN OLEFIN IN THE PRESENCE OF A CRYSTALLINE ALUMINOSILICATE ZEOLITE CATALYST EMPLOYING A REACTION MIXTURE IN WHICH THE MOLAR RATIO OF ISOPARAFFIN TO OLEFIN IS EXTREMELY LOW COMPARED TO CONVENTIONAL ALKYLATION, I.E. GENERALLY BELOW 3 TO 1 FOLLOWED BY REGENERATION AND REUSE OF THE CATALYST SO EMPLOYED.
Abstract:
A NEW AND UNUSUAL FAMILY OF CRYSTALLINE ZEOLITES IDENTIFIED AS ZEOLITE ZSM-4 ARE USED AS CATALYSTS FOR THE ISOMERIZATION AND DISPROPORTIONATION OF AROMATIC HYDROCARBONS.
Abstract:
ACID MORDENITE, A CRYSTALLINE ALUMINOSILICATE HAVING A RATIO OF SILICON ATOMS TO ALUMINUM ATOMS OF ABOUT 5 TO 1, IS USED AS A CATALYST FOR THE ISOMERIZATION OF XYLENES.
Abstract:
Conversion of methanol, and/or other lower aliphatic organic compounds containing at least one hetero atom, such as oxygen, sulfur, nitrogen or halogen, to higher hydrocarbons, notably hydrocarbons boiling in the gasoline boiling range, is known. The volatility of this synthetic, high octane gasoline are improved by admixing low octane natural gas liquids therewith, perhaps accompanied by addition to said admixture of n-butane as well.
Abstract:
A process for the simultaneous dewaxing of high pour point gas oil and upgrading of an aromatic containing naphtha by contact of a mixture of the gas oil and naphtha with a high silica to alumina ratio synthetic aluminosilicate zeolite catalyst, which is derived from a zeolite which was synthesized with an organic cation, incorporating a hydrogenation dehydrogenation component, and a hydrogen atmosphere at about 500* to 1,000*F followed by distillation of the product in order to recover a lower pour point gas oil fraction and a higher octane gasoline fraction.
