Influence of Different Temperature on Product Distribution law of waste oil steam cracking

摘要

Waste oil as raw material, study the possibility of waste oil steam cracking to produce light olefins, and focus on pyrolysis temperature on liquid product distribution law. The experimental results show that light olefins yield increases with the pyrolysis temperature; Waste oil first ester fault occurs for a variety of long-chain fatty acids. As temperature increases, the various fatty acids gradually pyrolysis of a variety of small molecules, and its acid value decreased, aromatic compounds in liquid products gradually increased, and fatty acid content decreased. Study the liquid product with temperature variation can take the effective use of waste oil, waste oil for a partial substitute for naphtha to supple the steam cracking feeds.
