Literature review on ethylbenzene production
Did you know?
WebEthylbenezene (EB) is important raw material for the production of styrene. Now, EB is mainly produced by the alkylation of benzene with ethylene catalyzed by zeolite in vapour phase or liquid phase. Shanghai Research Institute of Petrochemical Technology (SRIPT) began to research the catalysts for the production of ethylbenezene in 1993. WebCatalytic dehydrogenation of ethylbenzene is the main industrial method to produce styrene 1,2, which is a precursor molecule for the synthesis of rubbers and plastics. In practice, the catalytic dehydrogenation process itself is part of a complex reaction network including not only dehydrogenation but also side-reactions. Atanda and co-
WebIn 1983, the production of ethylbenzene in Western Europe was around 3 million tonnes (ECETOC 1986) with a similar amount produced in the USA (WHO 1996). Plant capacity in the UK was reported as around 310 000 tonnes in 1986, with he annual production figures predicted to remain at the 1986t level of 295 000 tonnes (DoE 1992). 2.3 Uses WebEthylbenzene is 1 of 4 aromatic solvents collectively referred to as BTEX (i.e., benzene, toluene, ethylbenzene, and xylene). All 4 solvents are commonly used components of gasoline and fuel oil. Ethylbenzene’s primary use is as a chemical intermediate in the production of styrene. It is
