摘要： The invention relates to a method for producing methacrylic acid from isobutane, which is characterized by subjecting the isobutane to a partial catalytic dehydration in the gas phase and feeding the resulting gas mixture containing isobutene to an oxidation zone once the components different from isobutane and isobutene have been substantially removed from the gas mixture. The oxygen required for charging the oxidation zone is added together with nitrogen.

摘要： The invention relates to a method for filling a vertical tube having an inner diameter of 50 mm or less with catalyst particles. According to said method, a filling aid comprising a flexible longitudinal body is introduced into the vertical tube, the ratio of the cross-section of the flexible longitudinal body to the cross-section of the tube being between 0.003 and 0.08, and the tube is filled with the catalyst particles.

摘要： The invention relates to a method for producing methacrolein from isobutane, which is characterized by subjecting the isobutane to a partial catalytic dehydration in the gas phase and feeding the resulting gas mixture containing isobutene to an oxidation zone in which the isobutene is oxidized to methacrolein in the gas phase by heterogeneous catalysis. Molecular oxygen is used as the oxygen source and is added together with molecular nitrogen.

摘要： The invention relates to a method for the thermal treatment of the precursor mass to an active catalytic mass in a rotating tube oven (2) with a through gas flow, whereby at least a partial amount of the gas flowing through the rotating tube oven is run in a loop (19). The invention further relates to the corresponding rotating tube oven device and tube bundle reactors, for the partial gas phase oxidation of acrolein to give acrylic acid, which are coated with the catalyst, the catalytic active mass of which may be obtained after the method for thermal treatment.
