利用含铜吸附剂之液态烃流纯化;PURIFICATION OF LIQUID HYDROCARBON STREAMS BY MEANS OF COPPER-CONTAINING SORBENTS

摘要

本发明关于一种纯化烃混合物之方法，其中藉由使包含具有三至八个碳原子之烃的受污染之烃混合物与固态吸附剂接触而使其至少部分排除污染物，在与该吸附剂接触期间，该烃混合物只为液态。其系意欲解决找出纯化液态C3至C8烃混合物之方法的问题，该方法应基于容易取得但非致癌性吸附剂且获致比传统分子筛更佳的纯度水准。此问题系藉由使用具有以下组成之固态材料作为吸附剂而获得解决：氧化铜：10重量%至60重量%(以CuO计算)；氧化锌：10重量%至60重量%(以ZnO计算)；氧化铝：10重量%至30重量%(以Al2O3计算)；其他物质：0重量%至5重量%。;此类材料另外系用作甲醇合成中之触媒。 The invention relates to a process for purifying hydrocarbon mixtures, in which a contaminated hydrocarbon mixture comprising hydrocarbons having three to eight carbon atoms is at least partly freed of contaminants by contacting it with a solid sorbent, the hydrocarbon mixture being exclusively in the liquid state during the contact with the sorbent. It addresses the problem of specifying a process for purifying liquid C3to C8hydrocarbon mixtures, which is based on a readily available but non-carcinogenic sorbent and which achieves better purity levels compared to traditional molecular sieves. This problem is solved by using, as the sorbent, solid materials of the following composition: ˙; ˙; ˙; ˙;Materials of this kind are otherwise used as catalysts in methanol synthesis.
