Overview

Octane destruction in FCC gasoline posttreaters

Many North American refineries have started increasing severity on gasoline posttreaters to make Tier 3 ultra-low sulfur gasoline. Our 3-year program of pilot plant and commercial field tests has shown that, when posttreater severity is increased, octane destruction will increase by much more than has been expected by the industry. Field tests on twelve different commercial posttreaters show clearly that the observed octane destruction is typically 5 times higher than is being expected. In this presentation, we will present data from commercial field tests during which our clients increased reactor temperatures to reduce sulfur to levels required for Tier 3 gasoline.
