Abstract: There are many types of alkylation technologies, among which the sulfuric acid alkylation process is mature and uses concentrated sulfuric acid as the catalyst. Sulfuric acid has strong corrosiveness and has special requirements for pipeline material selection. Ionic liquid alkylation is a new process technology that uses composite ionic liquids to replace traditional concentrated sulfuric acid as the catalyst. It is a new green, safe, and environmentally friendly alkylation technology. This paper introduces the special characteristics of these two alkylation technologies in pipeline material selection and pipeline piping.

Key words: alkylation, sulfuric acid, ionic liquids
