US Classification:
585481
Abstract:
Isomerization of xylenes admixed with other alkyl aromatics of at least eight carbon atoms and with normal or slightly branched paraffins is conducted at 800. degree. -1000. degree. F. with a zeolite like zeolite ZSM-5 of reduced acid activity.

International Classification:
C07C 100 C07C 120 C07C 122 C07C 530
US Classification:
585481
Abstract:
A zeolite of improved stability for use in acid-catalyzed reactions is prepared by mildly presteaming the catalyst under controlled conditions of temperature, time, and steam partial pressure. The resulting catalyst retains nearly the same activity as that of a fresh unsteamed catalyst.
Conversion Of Synthesis Gas To Liquid Hydrocarbons

Assignee:
Mobil Oil Corporation - New York NY
International Classification:
C07C 104
US Classification:
518713
Abstract:
This invention provides a process for converting synthesis gas to hydrocarbon fuels in the C. sub. 5 -C. sub. 24 (gasoline and distillate) range. The conversion proceeds with minimal formation of by-product fractions. The conversion is accomplished with a low nitrogen content iron catalyst intimately mixed with a selected zeolite.
Process For Converting Propane To Aromatics Over Zinc-Gallium Zeolite

Assignee:
Mobil Oil Corporation - New York NY
International Classification:
C07C 310 C07C 320
US Classification:
585415
Abstract:
The elution of zinc from zinc-impregnated zeolite catalysts is minimized by incorporating gallium into the catalyst composition. Optionally, palladium may also be included in the composition. The catalyst composition is used to effect the conversion of propane in hydrocarbon streams to aromatic hydrocarbons.

International Classification:
C07C 1202 C07C 1242
US Classification:
585415
Abstract:
A catalytic process is provided for converting gaseous feedstocks containing ethane to liquid aromatics by contacting said gaseous feeds in the absence of added air or oxygen, under conversion conditions, with a crystalline zeolite catalyst having incorporated therein a minor amount of gallium, thereby converting the ethane in the feedstock to aromatics and recovering a liquid mixture of benzene, toluene and xylene.

Assignee:
Mobil Oil Corporation - New York NY
International Classification:
C07C 1120
US Classification:
585408
Abstract:
A feedstock of low molecular weight oxygenates such as methanol and/or dimethylether is contacted with a mildly presteamed or hydro-thermally treated zeolite catalyst in a reaction zone to produce liquid hydrocarbons in the gasoline boiling range. The pretreated zeolite catalyst has an. alpha. -value (acid cracking activity) substantially the same as the. alpha. -value of fresh unsteamed catalyst and shows increased stability and resistance to aging under oxygenate conversion conditions of elevated temperature and pressure.
