Cracking processes Cycloversion

While natural or activated clay catalysts are no longer employed in the fixed-bed Houdry process, they are still widely used in the fluid process and to a considerable extent in the TCC process. A natural bauxite catalyst is employed in the fixed-bed cycloversion process, developed by the Phillips Petroleum Company. This process is of greater importance as a naphtha reforming process than as a catalytic cracking process. 

Commercial fixed-bed catalytic cracking includes the Houdry process and the Cycloversion process. Of the two, the Houdry process has been much more widely used. 

Fixed-bed Houdry and Cycloversion catalytic cracking, platinum catalyst reforming, the original Hydroforming installations, and the desulfurization processes are examples.
