摘要
Abstract
The polyethylene by-product polyethylene wax was characterized by high-temperature simulated distillation,infrared spectroscopy and thermogravimetric analysis. the polyethylene by-product polyethylene wax was pyrolyzed in an intermittent high-pressure reactor,and the effects of pyrolysis temperature,residence time and initial pressure on the yield of liquid product were investigated by orthogonal experiments. The light fractions (below 200 ℃)in the liquid products were analyzed by GC-MS. The results showed that:The polyethylene waxes were mainly composed of long chain aliphatic hydrocarbons(C14-C70);The pyrolysis temperature ranges from 175 ℃ to 490 ℃;Pyrolysis temperature and residence time were the main factors affecting the yield of liquid products;The light fractions were mainly α-olefins(accounting for 32.79%)and linear alkanes with carbon number distribution of C9-C20,and the single hydrocarbon with the highest content was 1-decene(8.46%),which was the high quality raw material to make poly-α-olefins for high grade synthetic lubricating oil.关键词
