A method for increasing the total amount of lattice metal in the framework of a particular porous inorganic crystalline composition, its conversion to hydrogen or hydronium form and use thereof as a catalyst component having enhanced catalytic activity for conversion of oxygenates to hydrocarbons is provided.

A method for synthesizing hydrocarbons from a methane source which comprises contacting methane with a reducible oxide of Fe. The iron oxide is preferably combined with an amount of alkali and/or alkaline earth metal which is sufficient to improve the selectively to higher hydrocarbon products. The oxide is reduced by the contact which is carried at about 500.degree. to 1000.degree. C. Reducible oxides of Fe are regenerated by oxidizing the reduced composition with oxygen. The oxide Fe.sub.3 O.s...

A method for synthesizing hydrocarbons from a methane source which comprises contacting methane with a reducible oxide of Tb. The Tb oxide is preferably combined with an amount of alkali and/or alkaline earth metal which is sufficient to improve the selectivity to higher hydrocarbon products. The oxide is reduced by the contact which is carried at about 500.degree. to 1000.degree. C. Reducible oxides of Tb are regenerated by oxidizing the reduced composition with molecular oxygen. The oxide Tb.s...

A method for synthesizing hydrocarbons from a methane source which comprises contacting methane with an oxide of Pr. The oxide is reduced by the contact which is carried at about 500.degree. to 1000.degree. C. Reducible oxides of Pr are regenerated by oxidizing the reduced composition with oxygen. The oxide Pr.sub.6 O.sub.11 is particularly effective in the process.

A continuous method for synthesizing hydrocarbons from a methane source which comprises contacting methane with moving beds of 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.

A method for increasing the total amount of lattice metal in the framework of a particular porous inorganic crystalline composition, its conversion to hydrogen or hydronium form and use thereof as a catalyst component having enhanced catalytic activity for conversion of paraffins and/or olefins to higher hydrocarbons is provided.

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 zeolite ZSM-58.

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.

Methane is converted to higher hydrocarbons, paticularly ethylene and ethane, and most desirably ethylene, by: contacting a feed comprising methane, such as natural gas, and a free oxygen containing gas, such as oxygen or air, with a solid contact material, comprising: (a) a component comprising: at least one metal selected from the group consisting of Group IA and Group IIA metals; (b) a component comprising: at least one material selected from the group consisting of phosphate radicals and com...

An off-highway vehicle suspension system strut of the type employing rubber impact pads to provide damping is modified by conversion of the housing to accommodate a nitrogen-over-oil suspension system. The rubber pads are removed and the inner barrel is capped with a piston. The outer barrel is fitted with a gas inlet valve, and an interface between the two barrels is created by a combination of one-way and two-way valves. Appropriate wall sections in the two barrels are reinforced or replaced t...
