A Review in Linear Alkylbenzene (LAB) Production Processes in the Petrochemical Industry

Linear alkylbenzene (LAB) is a cost-effective and biodegradable intermediate in the production of detergents surfactants. Recently, due to spread Coronavirus high global need for detergent, LAB essential. Kerosene raw material linear paraffin with purity, which are finally converted olefins by dehydrogenation. The mono-olefins react benzene existence catalyst produce used sulfonate (LAS), as detergent. main methods LAB, including HF Detal processes were studied compared each other. In method, many compounds such zeolites metal oxides have been make solid catalysts selectivity, long life, economic efficiency safety. Nowadays, most units process. this review, was investigated, influential factors advantages, disadvantages limitations method also investigated. product quality, process economics, sales market, quantitative qualitative properties Also, exact mechanism acid described.
