Styrene is an organic compound, derived from benzene. It is the raw material of polystyrene and it is naturally found in small proportions in cinnamon, coffee beans, peanuts, Lawsonia inermis (Henna tree) and plastics, as well as coal tree. Producing styrene in industrial quantity is typically done by catalytic dehydrogenation of ethyl benzene.
This process was firstly performed in 1958 by Emory Petzer et al. at the Philips Petroleum Company. After production of sulfuric acid catalyst and ammonia synthesis catalyst by Smart Catalyst Company, we are proudly presenting an advanced catalyst which is produced by styrene monomer with remarkable performance, this product presents one of the most challenging usages in industry and provides the conditions for maintaining the economic benefits of the industry. Opting a catalyst that has high efficiency under SHR conditions can remarkably reduce the cost of production in factories. this catalyst that remarkably increases styrene production performance while reducing energy consumption and greenhouse gas emissions. Styrene is a synthetic chemical material which is used so as to produce various kinds of plastic. Since this material is widely used, Smart Catalyst has been able to reduce the environmental effects of styrene production by this catalyst.

Smart Catalyst Company has been able to produce the most efficient styrene catalyst in Iran with highest activity and selectivity along with reducing costs and therefore increasing efficiency. Tests which have been performed demonstrate the strong performance of this catalyst. Thanks to its exclusive design, ethyl benzene (the ratio of vapor to hydrocarbon is also called SHR) achieves extraordinary activity and selectivity, at relatively low vapor conditions. The higher activity of catalyst increases the efficiency, while better selectivity reduces the by-products such as toluene and benzene, which usually have less value than styrene monomers. This issue is directly associated with economy and increasing efficiency for manufacturers and the petrochemical industry. Moreover, the optimal performance of the catalyst at SHR ratios makes styrene monomer production a more stable process. Particularly, the conversion process, which includes a new catalyst, consumes 82% less energy and reduces carbon dioxide emissions up to 79%.
