摘要： A method for producing acrolein and/or acrylic acid from propane, whereby the propane undergoes partial homogeneous and/or heterogeneous catalysed oxydehydrogenation in a first reaction step with molecular oxygen to form propane. The product gas mixture formed in the first reaction step is used to produce acrolein and/or acrylic acid by means of gas-phase catalytic propane oxidation. The method is characterised in that the molecular oxygen which is required in the first reaction area and is different from the recycled oxygen gas is added to the initial reaction gas mixture of the first reaction area as modified air containing nitrogen with the proviso that the nitrogen content of the modified air is lower than and the oxygen content of the modified air is greater than the corresponding air contents. The invention is further characterised in that at least one part of the molecular nitrogen contained in the flow of residual gas is separated from the residual gas flow before the residual gas flow is returned to the first reaction area.

摘要： The invention relates to a method for producing a catalyst, comprising an active phase, composed of a multi metal oxide and which is suitable for the gas-phase oxidation of organic compounds producing α,β unsaturated aldehydes and/or carboxylic acids. According to the invention, a particle shaped catalyst precursor is produced which contains oxides and/or compounds which can be transformed into oxides containing elements constituting the multi metal oxide mass which are different from oxygen. Said catalyst precursor can be transformed into a catalytically active form by means of calcination, whereby a flow of the particle shaped catalyst precursor for calcification is guided at a substantially constant speed through at least one calcification zone at a constant temperature.

摘要： Disclosed is a method for selective hydrogenation of citronellal to form citronellol, wherein a liquid phase in which the citronellal is dissolved and in which particles of a catalyst are suspended, said catatalyst resulting in preferential hydrogenation of carbon-oxygen double bonds in relation to carbon carbon bonds, is guided in the presence of a gas containing hydrogen through a device which inhibits the transport of the catalyst particles.
