<p>A process for the catalytic conversion of hydrocarbons comprises contacting the hydrocarbons at conversion conditions with a contact mass comprising two components one of which is a particle-form solid material which is catalytic or catalytically inert ranging from 200 mesh (U.S.) up to 0.14 inch in diameter, the second component comprising a zeolitic molecular sieve conversion catalyst, being in the form of particles ranging downwards in diameter from 15 microns and having at least some material of not more than 5 microns in diameter and sufficient of said second component to substantially coat the particles of said first component and to adhere to the surface of the particles thereof. Preferably the molecular sieve is base-exchanged with alkaline earth or rare earth compounds. Fixed, moving or fluidized bed methods may be used. The process may be used for the conversion of gas oil to gasoline.ALSO:A hydrocarbon conversion catalysts comprises two components, one of which is a particle form solid material which is catalytic or catalytically inert ranging from 200 mesh upwardly to 0.14 inch in diameter, the second component comprising a zeolitic molecular sieve conversion catalyst in the form of particles ranging downward in diameter from 15m , some material being not more than 5m in diameter, the second component being in sufficient quantity to adhere as a surface coating to the first component particles. The catalyst may be used as a fluidised bed.</p> |
