TEHRAN – The researchers at the Iran Petrochemical and Polymer Research Institute (IPPRI) have produced a new metal-free additive for gasoline that is used to increase the gasoline octane.

According to the reports released on Wednesday, Dr. Morteza Ehsani, head of the Polymer Technology Growth Center of IPPRI said here yesterday that despite all of the former additives, this new additive is added to gasoline in a lower density.

He went on to say that the current conventional gasoline additive that is MTBE (Methyl tert-butyl ether) is added to the gasoline for 5% to 10%; however, by adding some 0.06% of the new additive more satisfactory results will be seen.

Dr. Ehsani also noted that decreasing environmental pollution, increasing the efficiency of the car engines, being economical and easy-to-produce are the other privileges of the new gasoline additive.

He concluded that the Polymer Technology Growth Center has 30 technology units which welcome any new idea regarding polymer engineering, petrochemistry and pharmaceutics.
