    • A process is proposed for preparing acetylene by the Sachsse-Bartholomé process by combustion of a natural gas/oxygen mixture in one or more burners to obtain a cracking gas which is cooled in two or more stages in burner columns, each burner having one or more burner columns assigned thereto, and said cracking gas being quenched with pyrolysis oil in the first cooling stage, to obtain a low boiler fraction comprising benzene, toluene and xylene from the one or more burner columns, which is cooled with direct cooling water and separated in a phase separator into an aqueous phase and an organic phase which comprises benzene, toluene and xylene and is fully or partly introduced to the top of the one or more burner columns as a return stream, wherein the organic phase comprising benzene, toluene and xylene from the phase separator, prior to full or partial recycling to the top of the one or more burner columns, is supplied to a selective hydrogenation over a catalyst which comprises at least one platinum group metal on an inorganic metal oxide as support, comprising 0.05 to 5% by weight of platinum group metal, based on the total weight of the catalyst, and wherein the selective hydrogenation is performed at a pressure in the range from 10 to 70 bar gauge and a temperature in the range from 0 to 100° C.
    • 提出了一种通过Sachsse-Bartholomé方法通过在一个或多个燃烧器中燃烧天然气/氧气混合物来制备乙炔的方法,以获得在燃烧器柱中两级或更多级冷却的裂化气体,每个燃烧器具有一个或多个 燃烧器列,并且在第一冷却阶段,所述裂解气体用热解油淬火,以从一个或多个燃烧器柱获得包含苯,甲苯和二甲苯的低沸点馏分,其用直接冷却水冷却并分离 相分离器进入水相和有机相,其包含苯,甲苯和二甲苯,并作为回流完全或部分地引入到一个或多个燃烧器塔的顶部,其中有机相包含苯,甲苯和二甲苯 在完全或部分再循环到一个或多个燃烧器塔的顶部之前,将相分离器供应到催化剂上的选择性氢化,所述催化剂包括在l 在一个无机金属氧化物上的一个铂族金属作为载体,包含0.05-5重量%的铂族金属,基于催化剂的总重量,其中选择性氢化在10〜 70巴规,温度范围为0至100℃。
