Ionikylation is an alkylation technology used by refiners throughout Asia-Pacific as they seek to meet increasing clean fuel standards in a safe and environmentally friendly manner. Ionikylation uses a proprietary composite ionic liquid catalyst that eliminates reliance on dangerous, corrosive, and hazardous chemicals such as hydrogen fluoride and sulfuric acid. The entire system is constructed using carbon steel, and is an option for refiners that are looking to improve the safety of their operations without sacrificing utility.
