Abstract: Acrolein or acrylic acid is prepared by catalyzing partial gas phase oxidation of propene, where a starting reaction gas mixture having propylene and molecular oxygen reactants and inert molecular nitrogen and propane diluent gasses is conducted at elevated temperature through a fixed catalyst bed whose active composition is a multimetal oxide having molybdenum, iron and bismuth. Preparation of acrolein or acrylic acid involves catalyzing partial gas phase oxidation of propene, where a starting reaction gas mixture having propylene and molecular oxygen reactants and the inert molecular nitrogen and propane diluent gasses and having the molecular oxygen and the propylene in a molar oxygen;C 3H 6 ratio of >=1 is conducted at elevated temperature through a fixed catalyst bed whose active composition is a multimetal oxide having molybdenum, iron and bismuth based on its total volume of 6-9 vol.% propylene, 8-18 vol.% molecular oxygen. 6-30 vol.% propane and 32-72 vol.% molecular nitrogen. The molar ratio V 1 of propane in starting reaction gas mixture to propylene in starting reaction gas mixture is 1-4. The molar V 2 of molecular nitrogen present in starting reaction gas mixture to molecular oxygen in starting reaction the mixture is 2-6, and the molar ratio of the molecular oxygen in starting reaction gas mixture to propylene in starting reaction mixture is 1.3-2.4.

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.

Abstract: Production of acrolein/acrylic acid (IA/B) comprises dehydrogenation of gas feeds containing propane to gas containing propane and propylene, (partial) separation, gas phase partial oxidation with oxygen to gas containing (IA/B) and excess oxygen and separation, residual gas containing propane, oxygen and optionally propylene is (partly) recycled to first zone. Production of acrolein (IA) and/or acrylic acid (IB) from propane comprises: (1) passing not less than 2 feed gas streams containing propane, including not less than 1 containing fresh propane, into a first reaction zone A, where the propane is subjected to heterogeneously catalyzed dehydrogenation, giving a product gas mixture A containing propane and propylene; (2) passing this mixture (A) into a first separation zone A, in which other components are (partly) separated, leaving product gas mixture A' containing propane and propylene; (3) using A' in a second reaction B for charging oxidation reactor(s), in which propylene in A' is subjected to heterogeneously catalyzed gas phase partial oxidation with molecular oxygen to convert it to a product gas mixture B containing acrolein and/or acrylic acid as intended product and excess oxygen; and (4) separating product gas mixture B in a second separation zone B into the intended product containing product gas mixture B and a residual gas (V) containing unreacted propane, oxygen and optionally unreacted propylene which is (partly) recycled to reaction zone A as one feed stream. The novelty is that residual gas (V) is recycled to reaction zone A at a feed point where not less than 5 mole-% of propane in the other feed stream(s) has already been dehydrogenated.

Abstract: Preparation of at least one partial oxidation and/or ammoxidation product of propylene involves subjecting crude propylene (prepared by dehydrogenation or oxydehydrogenation in the presence and/or absence of oxygen) in the presence of unconverted propane as a constituent of a gas mixture 2 which comprises a total 4C-hydrocarbon content of at most 3 vol.%, to a heterogeneously catalyzed gas phase partial oxidation and/or ammoxidation. Preparation of at least one partial oxidation and/or ammoxidation product of propylene involves: (a) subjecting crude propane in the presence of and/or absence of oxygen to a homogeneously and/or a heterogeneously catalyzed dehydrogenation and/or oxydehydrogenation to obtain a propane- and propylene-containing gas mixture 1; (b) optionally removing and/or converting to other compounds a portion of the constituents other than propane and propylene contained in the gas mixture 1 to obtain a gas mixture 1' comprising propane and propylene and also compounds other than oxygen, propane and propylene; and (c) subjecting gas mixture 1 and/or gas mixture 1' as a constituent of a gas mixture 2 to a heterogeneously catalyzed gas phase partial oxidation and/or partial gas phase ammoxidation of propylene contained in gas mixture 1 and/or 1'. The total content of 4C-hydrocarbons of gas mixture 2 is at most 3 vol.%.
