A process for preparing a Catalyst zsm-5 modified Market

摘要

Process for producing a Catalyst zsm-5 modified.Comprising: (a) contacting a Hydrocarbon with a zsm-5 Catalyst has activity initially Cracking of paraffins,To provide small amounts of hydrocarbons with carbon Catalyst; (b) to regenerate the Catalyst Coke Burning carbon through AK) most of the Hydrocarbon Catalyst Coke Burning; BK) of the regenerated catalyst to produce a catalyst; The stages AK and BK) real Izan between 200 and 700jc and a pressure between 1 and 100 Atmospheres and with an O2 concentration between 120% mol O2; and (c) repeat Steps (a) and (b) and reduce the ability of Cracking of paraffins in 50%. Zeolites containing Rare Earths such as SM, ND, PR, CE and are Crystalline aluminosilicates. Used in the isomerization of the olefinas. -
