INTRODUCTION
The process of alkylating olefins with kerosenes was developed in the 1930s, and enjoyed a boom at the start of the Second World War to produce high-octane aviation fuels. More recently, the growing demand for gasoline and the reformulation of fuels (in particular, lower sulfur and aromatic content) has led to an increase in alkylate production capacity worldwide. Alkylates offer significant advantages over gasolines produced by other processes: their high octane rating helps to compensate for the disappearance of lead from gasoline, their low toxicity and their combustion give rise to the least polluting emissions.
The alkylation reaction involves reacting an isobutane molecule with a light olefin molecule to produce a gasoline cut consisting of kerosenes with carbon numbers between 5 and 12.

Statistical and economic data
Alkylation developed mainly in North America, where demand for synthetic gasolines was much higher than in Europe. Of a total of 46 Mt in 1982, over 85% (39 Mt) was manufactured in North America. In 2008, North America still accounted for the majority of alkylation capacity, with 47 Mt, or 58% of worldwide capacity.
