    Abstract: A process for the net catalytic oxidative dehydrogenation of alkanes to produce alkenes is provided. The process involves simultaneous equilibrium dehydrogenation of alkanes to alkenes and combustion of the hydrogen formed to drive the equilibrium dehydrogenation reaction further to the product alkenes. In the present reaction, the alkane feed is passed into a reactor containing both an equilibrium dehydrogenation catalyst and a reducible metal oxide, whereby the alkane is dehydrogenated and the hydrogen produced is simultaneously and selectively conbusted in oxidation/reduction (REDOX) reaction with the reducible metal oxide. This particular mode of operation is termed a same reactor, REDOX mode. The equilibrium dehydrogenation catalyst may comprise platinum and the reducible metal oxide may contain bismuth, antimony, indium, or molybdenum, or a mixture thereof.

    Abstract: A process for the net catalytic oxidative dehydrogenation of alkanes to produce alkenes is provided. The process involves simultaneous equilibrium dehydrogenation of alkanes to alkenes and combustion of the hydrogen formed to drive the equilibrium dehydrogenation reaction further to the product alkenes. In the present reaction, the alkane feed is dehydrogenated over an equilibrium dehydrogenation catalyst in a first reactor (110) and the effluent, along with oxygen is then passed into the second reactor (120) containing a metal oxide catalyst which serves to selectively catalyze the combustion of hydrogen. The equilibrium dehydrogenation catalyst may comprise platinum and the selective metal oxide combustion catalyst may contain bismuth, antimony, indium, or molybdenum, or a mixture thereof.

    Abstract: A process for shape-selective hydrocarbon conversion involves initially contacting a feedstream, which includes an alkylaromatic compound and a co-feed of water, under conversion conditions with a catalytic molecular sieve. Preferably, the catalytic molecular sieve has been modified by being ex situ selectivated with a silicon compound. After an effective amount of time, the water co-feed is omitted from the feedstream and the hydrocarbon conversion process is continued.

    Abstract: A method and apparatus for removing sulphur from a gas stream containing at least one sulphur compound, comprising cumbusting said gas stream with an oxygen containing gas in an incinerator (10) to convert the or each sulphur compound to at least one sulphur oxide. A gas stream is then withdrawn from the incinerator, which contains the or each sulphur oxide. The sulphur oxide containing gas stream is then directed to an absorber (12) having an absorbent bed adapted to remove sulphur compounds. The absorbent bed is then contacted with a hydrogen and/or hydrocarbon containing stream to regenerate said absorbent bed by reducing the sulphur compounds absorbed in said absorbent bed to hydrogen sulphide and/or sulphur dioxide, and thereby forming off gas stream containing hydrogen sulphide and/or sulphur dioxide. Finally, sulphur is recovered from said hydrogen sulphide and/or sulphur dioxide bearing stream. The sulphur can be recovered by a Claus sulphur recovery process (16). The hydrogen sulphide containing gas stream can be ammonia acid gas stream, thereby causing N2 to be formed in the incinerator. The N2 is not absorbed in the absorbent bed.
