Abstract: A process for the substantial reduction or complete elimination of ammonium sulfate generated during the production of acrylonitrile by the direct ammoxidation of propylene/propane, ammonia and an oxygen containing gas (e.g. air) over a fluid bed catalyst wherein the improvement comprises introducing methanol into said reactor in the upper portion of the reactor at a location where the methanol reacts with at least a portion if not substantially all of the excess ammonia without affecting the acrylonitrile yield. Preferably, methanol is introduced into the reactor at below its coking temperature. In particular, when an oxygen lean fluid bed catalyst is utilized, an additional oxygen containing gas is introduced into the reaction at a distance between about 8 to 14 inches from the methanol feed location.

Abstract: A process for preparing a supported solid oxide complex catalyst using silica as support characterised in that one adds fumed silica to a mixture containing one or more active components of the catalyst; dries said mixture to form a dried first-stage mixture; adds, in solution, silica or a silica-containing compound other than fumed silica to the dried first stage mixture optionally with further fumed silica; and dries and calcines the resulting mixture is provided. The use of fumed silica produces a supported solid oxide complex catalyst of increased attrition resistance. Such catalyst is useful in the preparation of unsaturated aldehydes and acids from propylene or isobutylene by vapour phase oxidation. The use of inert or recycle gas increases the performance of such catalyst in this reaction.

Abstract: The present invention relates to a catalyst composition consisting of oxide complexes of vanadium, molybdenum and germanium plus an additional oxide selected from the group consisting of iron, nickel, thallium, phosphorus, indium, bismuth and the rare earths and optionally an oxide selected from the group copper, magnesium, manganese, aluminum, titanium, potassium, rubidium, cesium, niobium, tantalum, chromium, tungsten, uranium, cobalt, silver, zinc, tin, gallium, arsenic and antimony. These catalysts are especially useful for producing acrylic acid from acrolein and for producing methacrylic acid from methacrolein.
