Abstract: Production of polyisobutene (I) from a starting 4C hydrocarbon stream (II), containing isobutene, 1-butene and 2-butene, includes: (a) distillatively separating (II) into a more volatile fraction (F1) (containing most of the isobutene and 1-butene in (II)) and a less volatile fraction (F2) (containing most of the 2-butene); and (b) subjecting the 1-butene in (F1) to chemically selective reaction and separating the reaction products from the remaining components of (F1).

Abstract: Phthalic anhydride is prepared by catalytic gas-phase oxidation of xylene and/or naphthalene by a gas comprising molecular oxygen in a fixed bed at elevated temperature and using at least three coated catalysts arranged in superposed zones, which catalysts have a layer of catalytically active metal oxides applied to a core of support material. In the process described, the catalyst activity rises from zone to zone from the gas inlet end to the gas outlet end and the activity of the catalysts of the individual zones is set such that the least active catalyst comprises a lower amount of active composition and, if desired, additionally more alkali metal selected from the group consisting of potassium, rubidium and cesium as dopant than the catalyst of the next zone and the subsequent even more active catalyst comprises the same amount of active composition and even less alkali metal as dopant or a greater amount of active composition and, if desired, less alkali metal as dopant than the catalyst of the second zone, with further conditions.

Abstract: The invention relates to a shell catalyst with a core and at least one shell surrounding the core, said core being composed of an inert carrier material, and the at least one shell being composed of a porous carrier substance. The shell is physically adhered to the core and the at least one shell contains a catalytically active metal selected from the group of metals of the 10 and 11 group of the periodic table of elements in a finely divided form, or a precursor of the catalytically active metal in a uniformly divided form. The inventive shell catalyst is suitable for reducing unsaturated hydrocarbons and allows for better selectivities in comparison with shell catalysts known so far. The invention further relates to a method for producing the inventive shell catalyst.
