Abstract: Described herein is a process for providing a catalytically active fixed bed for hydrogenation of organic compounds, in which a fixed bed including monolithic shaped bodies as catalyst supports or consisting of monolithic shaped bodies is introduced into a reactor and the fixed bed is then contacted with at least one catalyst or a precursor thereof. The fixed beds laden with a catalyst that are obtained in this way are especially suitable for the hydrogenation of organic compounds in the presence of CO, wherein the conversion is at least 90%. They are notable in that only a very small proportion, if any, of the catalyst introduced is released into the reaction medium.

Abstract: The present invention relates to a process for preparing cyclohexane by isomerizing a hydrocarbon mixture (HM1) comprising methylcyclopentane (MCP) in the presence of a catalyst. The catalyst is preferably an acidic ionic liquid. The starting material used is a stream (S1) which originates from a steamcracking process. The hydrocarbon mixture (HM1) obtained from this stream (S1) in an apparatus for aromatics removal has a reduced aromatics content compared to stream (S1), and (HM1) may optionally also be (virtually) free of aromatics. Depending on the type and amount of the aromatics remaining in the hydrocarbon mixture (HM1), especially in the case that benzene is present, the isomerization may additionally be preceded by performance of a hydrogenation of (HM1). In addition, depending on the presence of other components of (HM1), further purification steps may optionally be performed prior to or after the isomerization or hydrogenation. High-purity (on-spec) cyclohexane is preferably isolated from the hydrocarbon mixture (HM2) obtained in the isomerization, the specifications being, for example, those applicable to the use of the cyclohexane for the preparation, known to those skilled in the art, of caprolactam.

Abstract translation: 本发明涉及通过在催化剂存在下异构化包含甲基环戊烷（MCP）的烃混合物（HM1）来制备环己烷的方法。 催化剂优选为酸性离子液体。 使用的起始材料是来自蒸汽裂化过程的流（S1）。 在与物流（S1）相比，用于除去芳烃的装置中从该料流（S1）获得的烃混合物（HM1）具有降低的芳族化合物含量，（HM1）也可任选地（实际上）不含芳族化合物。 取决于残留在烃混合物（HM1）中的芳族化合物的类型和量，特别是在存在苯的情况下，异构化可另外进行（HM1）的氢化。 此外，根据（HM1）的其它组分的存在，可以任选地在异构化或氢化之前或之后进行进一步的纯化步骤。 高纯度（特定）环己烷优选与在异构化中获得的烃混合物（HM2）分离，其规格是例如适用于本领域技术人员已知的用于制备环己烷的那些 的己内酰胺。

Abstract: A process for hydrogenating a hydrogenatable organic compound in a reactor including a fixed catalyst bed. The fixed catalyst bed includes monolithic shaped catalyst bodies having pores and/or channels. The catalyst bodies include at least one element selected from Ni, Fe, Co, Cu, Cr, Pt, Ag, Au, Pd, Mn, Re, Ru, Rh and Ir. The CO content in the gas phase within the reactor during hydrogenation is within a range from 0.1 to 10,000 ppm by volume. In any section in the normal plane to flow direction through the fixed catalyst bed, at least 90% of the pores and channels have an area of not more than 3 mm2.
