    摘要： A combustion process, e.g. for a gas turbine, comprises catalytically combusting part of a fuel/air feed in a preliminary catalyst body which has through passages and supports, or is composed of, a catalyst active for the combustion of the fuel. The resultant heated gas stream is then mixed with the remainder of the feed, and that mixture is combusted, e.g. catalytically in a main catalyst body. The amount of combustion occurring in the preliminary catalyst body is sufficient that combustion of the mixture of the heated gas stream and the remainder of the feed can be sustained at the desired operating conditions. Under those desired operating conditions combustion of the feed could not be sustained in the absence of the heating given by the combustion in the preliminary catalyst body. There may be more than one preliminary catalyst body. The preliminary catalyst body or bodies may also be provided with passages wherein combustion does not take place under the desired operating conditions so that those passages act as a bypass. Preferably the combustion passages of at least the first preliminary catalyst body are of such size, that at the normal operating conditions, the flow therethrough is laminar, whereas the flow through the passages of the main catalyst body, where employed, is turbulent.

    摘要： Compositions suitable for use as oxidation catalysts essentially free from elements, or compounds thereof, of Group VIII of the Periodic Table, comprise an intimate mixture of oxides of at least three elements selected from Groups IIIa and IVa of the Periodic Table, including, of the total number of Group IIIa and IVa element atoms present, a) a total of at least 60% of atoms of at least one element X selected from cerium, zirconium, and hafnium, b) a total of at least 5% of atoms of at least one other element Y different from element X and selected from the variable valency elements titanium, cerium, praseodymium, and terbium; and c) a total of at least 5% of atoms of at least one element Z differing from X and Y and selected from Group IIIa elements.Such compositions, and similar two component compositions wherein X and Y are both cerium, have, after heating for 8 hours at 1200.degree. C., a BET surface area of at least 1 m.sup.2.g.sup.-1 and are particularly useful for the oxidation of a feedstock with an oxygen-containing gas, eg catalytic combustion, especially under conditions such that the catalyst attains a temperature of at least 1000.degree.

    摘要： A process for production of hydrocarbons including a) reforming a divided hydrocarbon feedstock stream, mixing the first stream with steam, passing the mixture over a catalyst disposed in heated heat exchange reformer tubes to form a primary reformed gas, forming a secondary reformer feed stream including the primary reformed gas and the second hydrocarbon stream, partially combusting the secondary reformer feed stream and bringing the partially combusted gas towards equilibrium over a secondary catalyst, and producing a partially cooled reformed gas, b) further cooling the partially cooled reformed gas below the dew point of steam therein to condense water and separating condensed water to give a de-watered synthesis gas, c) synthesising hydrocarbons from the de-watered synthesis gas by the Fischer-Tropsch reaction and separating some of the synthesised hydrocarbons into a tail gas, and d) incorporating part of the tail gas into the secondary reformer feed stream before partial combustion thereof.
