Ethylbenzene-based technology is used in around 90% of styrene production. The catalytic alkylation of EB using aluminum chloride or other catalysts is the first step in the production process (i.e. zeolite catalysts). Using either multiple bed adiabatic or tubular isothermal reactors, the EB is subsequently dehydrogenated to styrene in the presence of steam at high temperatures over iron-chromium oxides or zinc oxide catalysts. The demand for styrene in liquid form is estimated to be more than 15 million metric tons, and it is primarily determined by the demand for its various applications. Western and Eastern Europe, as well as North America, have the highest yearly capacity for styrene manufacturing.
