In Part 1 of this two-part series, recent technology developments to convert hydrofluoric acid (HF) alkylation to sulfuric acid alkylation were discussed.
Because of its clean-fuel properties (paraffinic, high octane, low vapor pressure and very low sulfur), alkylate is considered one of the most desired components in the gasoline pool.
