Process for production of synthesis gas in which a saturated hydrocarbon and an oxygen containing gas having a ratio of hydrocarbon to oxygen of greater than the stoichiometric ratio for complete combustion are introduced into a bed of particulate material. The bed comprises material which is catalytically active for partial oxidation and/or steam reforming reactions. The upward flow rate of the hydrocarbon/oxygen containing gas stream is sufficiently large to cause a spouting action of the bed ...

A process is provided for converting feedstock comprising C.sub.2.sup.+ olefins, C.sub.2 -C.sub.7 paraffins or mixtures thereof to product comprising C.sub.5.sup.+ hydrocarbons over a catalyst comprising a siliceous zeolite prepared by the method comprising providing zeolite Beta containing boron and aluminum, treating the zeolite with silicon tetrachloride at a temperature and for a time sufficient to replace boron with silicon, and recovering the siliceous zeolite having reduced boron content ...

A method is disclosed for converting methane to higher hydrocarbon product by contacting methane with a contact solid which comprises a reducible metal oxide which when contacted with methane at a temperature within the range of about 500.degree. to 1000.degree. C. is reduced and produces higher hydrocarbon products and water; and a promoting amount of at least one halogen component.

A method for synthesizing hydrocarbons from a methane source which comprises contacting methane with an oxidative synthesizing agent under elevated pressures, preferably at pressures within the range of about 5 to 30 atmospheres. Particularly effective oxidative synthesizing agents are reducible oxides of metals selected from the group consisting of Mn,Sn,In,Ge,Pb,Sb, and Bi.

A method is disclosed for converting methane to higher hydrocarbon product by contacting methane with a solid which comprises a reducible metal oxide which when contacted with methane at a temperature within the range of about 500.degree. to 1000.degree. C. is reduced and produces higher hydrocarbon products and a promoting amount of at least one chalcogen component. The preferred chalcogen components are selected from a group consisting of sulfur, selenium, tellurium, and compounds thereof.

An improved method for converting methane to higher hydrocarbon products by contacting a gas comprising methane and a reducible metal oxide under synthesis conditions, the improvement which comprises performing the contacting in the presence of oxides of nitrogen. Nitrous oxide is a preferred nitrogen oxide.

A continuous method for synthesizing hydrocarbons from a methane source which comprises contacting methane with particles comprising an oxidative synthesizing agent under synthesis conditions wherein particles recirculate between two physically separate zones: a methane contact zone and an oxygen contact zone. Preferably, particles are maintained in each of the two zones as fluidized beds of solids. Particularly effective oxidative synthesizing agents are reducible oxides of metals selected from...

Pitch is converted to mesophase pitch in the presence of catalytically effective amounts of oxides, diketones, carboxylates and carbonyls of metals selected from vanadium, chromium, molybdenum, iron, nickel and cobalt. The crystalloidal or mesophase pitch obtained can be used for the production of carbon fibers and other carbon and graphite products and articles of manufacture of unusually high quality.

Olefins are converted into other olefins having different numbers of carbon atoms by contact with a catalyst comprising a silica support containing tungsten oxide and a promoting amount of at least one titaniferous agent and activated under conditions suitable for the titaniferous agent to promote the activity of tungsten oxide and silica for the disproportionation and isomerization reaction.

A method for synthesizing hydrocarbons from a methane source which comprises contacting methane with an oxide of Ru. The oxide is reduced by the contact which is carried at about 500.degree. to 1000.degree. C. Reducible oxides of Ru are regenerated by oxidizing the reduced composition with oxygen.
