Abstract: A dry, intimate mixture of ammonium ion-containing catalyst precursors is heated at a rate of up to 10 degrees C/min to decomposition in the range 240-360 degrees C. It is held in this range until 90 mol% or more of ammonia released above 160 degrees C has been evolved. At no higher than 230 degrees C, the molecular oxygen content of the atmosphere A where the thermal treatment takes place is reduced to at most 0.5 vol%. This lower oxygen content is maintained until the total ammonia released reaches 20 mol%. A dry, intimate mixture of ammonium ion-containing catalyst precursors is heated at a rate of up to 10 degrees C/min to decomposition in the range 240-360 degrees C. It is held in this range until 90 mol% or more of ammonia released above 160 degrees C has been evolved. At no higher than 230 degrees C, the molecular oxygen content of the atmosphere A where the thermal treatment takes place is reduced to at most 0.5 vol%. This lower oxygen content is maintained until the total ammonia released reaches 20 mol%. At the earliest when more than 70 mol% of the ammonia has been released, the mixture is heated above the decomposition temperature range, at 10 degrees C/min, to reach the calcining temperature range of 380-450 degrees C. At the latest, when 98 mol% of the total ammonia has been released during the entire course of thermal treatment, the molecular oxygen content of the atmosphere A is raised to above 0.5 vol%-4.0 vol%. The intimate dry mixtures is then calcined in the calcination temperature range, under the increased oxygen content.

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: Catalyst (A) comprises active oxygen compounds of molybdenum and/or tungsten (I) on an oxide carrier and is prepared by: (i) applying precursors of (I) to the carrier (or its precursor); and (ii) calcining at 400-900 deg C. It is characterized by having transport pores of diameter over 25 nm and transport pore volume at least 50 mm /g. Independent claims are also included for: (a) method for preparing (A); and (b) preparation of poly(tetrahydrofuran) or tetrahydrofuran (THF) copolymers (or their di- or mono-esters) by polymerization of THF in presence of at least one telogen and/or comonomer, and in presence of (A).
