Abstract

A process for the isomerization of paraffin wax comprises vaporizing a paraffin wax and contacting the vapours, mixed with at least one mol. of hydrogen per mol. of wax and in the absence of any liquid phase, with a supported platinum catalyst at a temperature between 300 DEG C. and 550 DEG C. The carrier for the catalyst is preferably activated alumina, free from alkaline substances, and the catalyst may contain 0.05 per cent. to 1.0 per cent. platinum. The vaporized wax is preferably mixed with hydrogen in mol. ratio of at least 1:5, and the conditions should be such as to prevent condensation to a liquid phase. The contact time may be between 0.5 and 25 seconds and should be insufficient to produce more than 25 per cent. conversion to cracked products. The temperature is preferably between 375 DEG C. and 490 DEG C. and the pressure may be between 3.5 and 210 atmospheres, preferably between 21 and 70 atmospheres. The product consists of normally liquid oil, uncoverted wax, partially converted wax and cracked products. The last are removed by distillation, and the wax may be removed from the oil and recycled, to give a high quality lubricating oil.
