Abstract: Disclosed is a method for producing a catalyst containing vanadium, phosphorus, and oxygen, which is used for oxidizing the gas phase of a hydrocarbon having at least four carbon atoms to maleic anhydride. According to the inventive method, a corresponding catalyst precursor which contains vanadium, phosphorus, and oxygen and is provided with particles having an average diameter of at least 2 mm is converted into a catalytically active form by means of calcination, and a flow of the catalyst precursor is transported on a conveyor belt across at least one calcination area over a distance 1 n at an essentially steady speed in order to be calcinated. The variation over time of the gas temperature in relation to the set point value amounts to n /2 of the calcination area, while the local difference in the gas temperature between any positions in the area of the flow of the catalyst precursor, which is located within the second half 1 n /2 of the calcination area, amounts to

A process for the production of a vanadium, phosphorous and oxygen containing catalyst precursor (I) for the production of maleic acid anhydride by heterogeneously catalyzed gas phase oxidation of an at least 4C-hydrocarbon comprises reaction of vanadium pentoxide with a 5- or 3-valent phosphorous compound in the presence of a prim. or sec. optionally cyclic or branched 3-6C saturated alcohol with stirring at 80-160 degrees C followed by filtration of the resulting suspension such that at least two of the following measures are observed (a) addition of the phosphorous compound to a suspension of the alcohol and vanadium pentoxide at 50-160 degrees C whereby the contact time between the vanadium pentoxide and the alcohol prior to the addition of the phosphorous compound is no greater than 1 hour at a temperature of at least 50 degrees C; (b) mixing of the vanadium pentoxide with the phosphorous compound in the presence of the alcohol at 0-50 degrees C followed by heating to 50-160 degrees C at a rate of at least 1.5 degreesC/minute; (c) adjusting the mixing regime of the suspension to 0.01-0.6 W/kg (with respect to the physical-chemical properties of the mixed ingredients at 20 degrees C prior to reaction) and; (d) filtration at 65-160 degreesC at a filtration resistance value of no greater than 50 x 1013 mPa.s/m2 Independent claims are included for (1) the resulting catalyst precursor(I); (2) a process for the production of a catalyst (II) from the precursor (I) by contacting the precursor (I) with an atmosphere comprising oxygen, water vapor and/or an inert gas at 250-600 degrees C; (3) the resulting catalyst (II); (4) a process for the production of maleic acid anhydride at contacting an at least 4C hydrocarbon with an oxygen containing gas in the presence of catalyst (II).

Abstract: Production of maleic anhydride comprises the heterogeneous-catalyzed gas-phase oxidation of an n-butene-containing hydrocarbon stream with oxygen. A two-sequential-zone tubular bundle reactor is used which has heat-transfer cycles at both the inlet-side zone and the product-side zone. Production of maleic anhydride comprises the heterogeneous-catalyzed gas-phase oxidation of an n-butene-containing hydrocarbon stream, with an oxygen-containing gas. The process is carried out in a two-zone tubular bundle reactor with a catalyst for oxydehydrogenation of the n-butene to 1,3-butadiene in the inlet-side zone and a catalyst for the oxidation of 1,3-butadiene to maleic anhydride on the product side and with the reactor having heat-transfer cycles at both zones.

Abstract: The disclosure involves a process for the preparation of butadiene and 1-butene. The process includes at least a first catalytic dehydrogenation of n-butane to obtain a gas stream which is followed by at least a second oxidative dehydrogenation to form a second gas stream. The second gas stream is then subjected to distillation and isomeration steps to obtain butadiene and 1-butene.

Abstract: The disclosure relates to a process for preparing butadiene. The process involves nonoxidatively catalytically dehydrogenating butane to obtain a product gas stream containing butane, 1-butene, 2-butene, butadiene, hydrogen and secondary constituents. The 1-butene and 2-butene of the product gas stream is then oxidatively dehydrogenated to give a second gas stream containing butane,2-butene, butadiene, hydrogen, steam and secondary constituents. Next, the butane,2-butene and butadiene are separated from the second gas stream and the butane and 2-butene are then separated from the butadiene product. The butane and 2-butene are then recycled into the nonoxidative catalytic dehydrogenating zone.
