摘要： A catalyst for the total hydrogenation of an olefin-containing hydrocarbon stream can be made. The catalyst has a support material and platinum as a catalytically active metal. A process for the total hydrogenation of an olefin-containing hydrocarbon stream in at least one reactor with addition of hydrogen and using the catalyst can be performed.

摘要： A process discharges low boilers during production of dialkyl terephthalates or dialkyl phthalates having C8 to C11 alkyl radicals. The production is carried out using a C8 to C11 alcohol or a mixture of two or more C8 to C11 alcohols in one or more reactors. The low boilers formed during the reaction are separated off by an efficient process and thus cannot accumulate.

摘要： A process for hydroformylating short-chain olefins, especially C2 to C5 olefins can be performed in at least one reactor in which the catalyst system is in heterogenized form on a support. The support is composed of a porous ceramic material, and the process steps a) to c) are conducted when the process is shut down.
