    • A process for the catalytic epoxidation of olefins in at least one reaction stage comprising: (a) reacting the olefin with hydrogen peroxide in an organic, water-miscible solvent in the presence of a titanium silicalite catalyst in a reactor while continuously feeding an inert gas stream into the reactor, (b) continuously removing an exit gas stream containing olefin oxide, unreacted olefin, oxygen and inert gas from the reactor, (c) bringing the exit gas stream into contact in an absorption unit with the same solvent as used in the reaction stage, (d) removing a solvent stream loaded with olefin and olefin oxide from the absorption unit and (e) discharging an gas stream containing oxygen and the inert gas from the absorption unit.

    • A process for the recovery of combustible components of a gas stream containing the combustible components and oxygen by selective absorption of the combustible components in a solvent, whereby during the absorption the gas phase is dispersed in a continuous liquid phase of the solvent. In a preferred embodiment the process is applied to give a process for the epoxidation of propene with hydrogen peroxide in the alcoholic solvent in presence of a catalyst, wherein a gas stream including unreacted propene, propene oxide and oxygen from the decomposition of the hydrogen peroxide is separated from the epoxidation reaction mixture and the combustible components in said gas stream are recovered using the process as described above.
    • 通过在溶剂中选择性吸收可燃组分来回收含有可燃组分和氧的气流的可燃组分的方法,由此在吸收期间气相分散在溶剂的连续液相中。 在优选的实施方案中,应用该方法以在催化剂存在下,在醇溶剂中用过氧化氢环氧化丙烯的方法,其中包含未反应的丙烯,氧化丙烯和来自过氧化氢分解的氧的气流是 与环氧化反应混合物分离,并使用上述方法回收所述气流中的可燃组分。
