Abstract: To meet the demand of domestic refineries for alkylate, an authorized low acid consumption sulfuric acid alkylation technology was developed by RIPP through the development of new reactors, enhanced mass transfer and separation processes. The demonstration plant test was conducted in an 80 t/a sulfuric acid alkylation unit built in SINOPEC Shijiazhuang Refining & Chemical Company. The test showed that the RON of the product was 96.5~97.0, the final boiling point was less than 197.5 °C. It meets the requirements of alkylation product and is a high-quality gasoline blending component. The acid consumption was determined to be 46.4 kg/t of alkylation product during the stable operation period, lower than the conventional technology.

Key words: sulfuric acid alkylation, demonstration unit, octane number, low acid consumption
