The invention relates to a method for cleaning hydrocarbon mixtures, in which a contaminated hydrocarbon mixture comprising hydrocarbons having three to eight carbon atoms is at least partly freed of impurities by contacting with a solid sorbent, wherein the hydrocarbon mixture is exclusively in the liquid state during contact with the sorbent. The object of the invention is to specify a process for cleaning liquid Cto Chydrocarbon mixtures, which is based on a readily available but non-carcinogenic sorbent and which achieves better purities compared to traditional molecular sieves. This object is achieved by using, as sorbents, solid materials of the following composition: Materials of this kind are otherwise used as catalysts in methanol synthesis.
