Researchers at the Iran Petrochemical and Polymer Research Institute (IPPRI) have produced a new metal-free additive for gasoline that can increase the gasoline's octane, reported Tehran Times in an article on Thursday.
Dr Morteza Ehsani, head of the Polymer Technology Growth Center of IPPRI, said Wednesday that this discovery has the advantage over all other additives in that it is added to gasoline in a lower density.
He went on to say that current conventional gasoline additives, that is MTBE (methyl-tert-butyl-ether) is added to gasoline at a concentration of 5 percent to 10 percent. In contrast, by adding some 0.06 percent of the new additive more satisfactory results can be achieved.
Dr Ehsani also noted that its ability to decrease environmental pollution, increase the efficiency of car engines, economy and easy-to-produce qualities are other advantages of the new gasoline additive.
He concluded by saying that the Polymer Technology Growth Center has 30 technology units which welcome new ideas regarding polymer engineering, petrochemistry and pharmaceutics.
