Classified as: Cracking, Hydro
Hydrocracking involves breaking longer chain linear alkanes into shorter branched alkanes in the presence of hydrogen. If an LPG stram is added, a wide range of materials can be produced: the proceess can be optimised for: isobutane, gasoline, naphtha, kerosene or fuel oil.
Shape selective zeolite catalysts are used. At the 240-450°C cracking temperatures and 80-200 bar pressure, long linear alkanes are thermodynamically unstable with respect to shorter and branced alkanes (and even C + H2, coke deposits on the catalyst).Gas Oil |
