Production of methane and aromatics

Abstract: A COMBINED AROMATIZATION AND LIGHT GAS HYDROGENOLYSIS WHEREBY NAPHTHA OR LIGHT GAS HYDROCARBONS ARE INITIALLY AROMATIZED IN CONTACT WITH A ZSM-5 TYPE OF SYNTHETIC ALUMINOSILICATE ZEOLITE MOLECULAR SIEVE UNDER SPECIFIED CONDITIONS TO PRODUCE A PRODUCT AT LEAST 30 WEIGHT PERCENT OF WHICH IS A MIXTUE OF AROMATIC HYDROCARBONS, AND THE REMAINDER OF WHICH IS A GASEOUS MIXTURE OF HYDROGEN AND LOWER MOLECULAR WEIGHT HYDROCARBONS. THE GASEOUS MIXTURE IS CHARACTERIZED BY AN ATOM RATIO OF ABOUT 1 CARBON ATOM TO 4 HYDROGEN ATOMS. THIS GAS IS CONTACTED WITH A HYDROGENOLYSIS CATALYST, SUCH AS NICKEL, AT A TEMPERATURE OF ABOUT 525 TO 1000*F. AND A PRESSURE OF ABOUT 0 TO 200 P.S.I.G. TO CONVERT AT LEAST MOST, AND PREFERABLY SUBSTANTIALLY ALL OF THE HYDROGEN AND THE CARBON IN THE HYDROCARBON COMPONENTS TO A SYNTHETIC NATURAL GAS WHICH IS THERMALLY AND PHYSICALLY COMPATIBLE WITH NATURAL GAS.

Method for simultaneously producing synthetic natural gas and high octane reformate

Abstract: A SYNTHETIC NATURAL GAS STREAM AND A HIGH OCTANE REFORMATE STREAM ARE PRODUCED BY CONTACTING A HYDROCARBON CHARGE STOCK BOILING IN THE GASOLINE RANGE AND HYDROGEN, AT SYNTHETIC NATURAL GAS PRODUCTION CONDITIONS, WITH A CATALYTIC COMPOSITE COMPRISING A POROUS CARRIER MATERIAL CONTAINING, ON AN ELEMENTAL BASIS, ABOUT 0.01 TO ABOUT 2 WT. PERCENT OF APLATINUM GROUP METAL, ABOUT 1 TO ABOUT 5 WT. PERCENT NICKEL AND ABOUT 0.01 TO ABOUT 5 WT. PERCENT PF A GROUP IVA METAL. SYNTHETIC NATURAL GAS PRODUCTION CONDITIONS GENERALLY UTILIZED INCLUDE A TEMPERATURE OF ABOUT 900 TO ABOUT 1200*F., A PRESSURE OF ABOUT 0 TO ABOUT 350 P.S.I.G., LIQUID HOURLY SPACED VELOCITY ABOUT 0.5 TO ABOUT 3 HRS.-1 AND A MOLE RATIO OF HYDROGEN TO HYDROCARBON OF ABOUT 1:1 TO ABOUT 5:1.

Method for production of synthetic natural gas from crude oil

Abstract: A process for the production of a pipeline gas of high BTU content from crude oil by hydrogasification of the crude oil. The crude oil is first vaporized in the presence of hydrogen and then gasified to form an effluent gas containing essentially methane, ethane, aromatic hydrocarbons, hyrogen and hydrogen sulfide. After separation of the aromatics and hydrogen sulfide from the effluent, the effluent is subjected to cryogenic separation of the hydrogen and a final catalytic conversion of the ethane to methane.

Synthetic natural gas production using a plug-flow reactor

Abstract: A multi-zone-plug-flow-reactor is used to produce synthetic natural gas (SNG) by thermal hydrocracking. A vaporized hydrocarbon feed and a portion of the required hydrogen is fed downwardly through the reactor initially at 800* to 1,200*F and above 200 psig. The partially thermally hydrocracked hydrocarbon feed is stepwise quenched to maintain a temperature differential of 150*F maximum between each zone and the remainder of the hydrogen is mixed with the feed at various points within the reactor to complete the hydrocracking in the last zone and thereby provide a product which is quenched to a temperature at which no further hydrocracking will occur. The reactor product is cryogenically separated to provide recycle hydrogen, gas for hydrogen generation and the SNG product.

Process for the transportation of acid gases in natural gas liquids streams

Abstract: LIQUIDS STREAM, TRANSPORTING THE DRIED ACID GAS AND NATURAL GAS LIQUIDS MIXTURE THROUGH A PIPE LINE TO A SEPARATION ZONE AND RECOVERING THEREIN THE ACID GAS CONTENT OF SAID GAS AND NATURAL GAS LIQUIDS MIXTURE. A PROCESS FOR THE PREPARATION AND TRANSPORTATION OF AN AT LEAST PARTIALLY DEHYDRATED ACID GAS/NATURAL GAS LIQUIDS MIXTURE IS DESCRIBED WHICH COMPRISES SEPARATING A SOUR FIELD NATURAL GAS STREAM INTO A NATURAL GAS STREAM, AN ACID GAS STREAM AND A NATURAL GAS LIQUIDS STREAM, DYRING THE SEPARATED ACID GAS STREAM AND NATURAL GAS LIQUIDS STREAM, MIXING THE DRIED ACID GAS STREAM AND DRIED NATURAL GAS
