DCC needs more steam than FCC but much less than steam cracking. Table.1 General comparison between DCC and FCC Process FCC DCC Feedstock A wide range of heavy oils A wide range of heavy oils, preferably paraffins Catalyst Various types of Y zeolite catalyst A modified pentasil structure ...
Gasoline demand is weakening as diesel becomes more widely used. At the same time, propylene demand is soaring and the steam cracking route is unable to keep up. In response, Shell Catalysts & Technologies has developed the MILOS (Middle distillate and Lower Olefins Select...

These tests also provided possible reaction mechanisms where thermal cracking competes with catalytic processes. Bench-scale, fixed bed reactor tests demonstrated high hydrogen yields from model compounds and carbohydrate-derived pyrolysis oil fractions. Reforming bio-oil or its fractions required proper ...
