Catalytic Hydrocracking—Mechanisms and Versatility of the Process

  title={Catalytic Hydrocracking—Mechanisms and Versatility of the Process},
  author={J. Weitkamp},
Hydrocracking of saturated hydrocarbons can proceed by means of four distinctly different mechanisms. On bifunctional catalysts comprising hydrogenation/dehydrogenation and Brønsted acid sites alkenes and carbocations occur as intermediates. The current mechanistic views of bifunctional hydrocracking of long‐chain n‐alkanes are discussed in detail with emphasis on the now widely accepted concept of ideal hydrocracking. Other mechanisms are hydrogenolysis and Haag–Dessau hydrocracking which… Expand
