Katalytisk delvis oksidasjon med forbedret antenningssystem

摘要

The instant invention is directed to a catalytic partial oxidation (CPO) process with improved ignition comprising; (a) igniting an ignition feed comprising hydrogen, diluent and oxygen in a catalytic partial oxidation catalyst bed wherein said ignition feed has a predetermined adiabatic reaction temperature sufficient to cause said catalyst bed to ignite in a manner which prevents said catalyst bed from undergoing thermal shock, (b) modifying said ignition feed following said ignition of said catalyst bed to obtain a reaction feed comprising oxygen and hydrocarbon-reactant in a molar ratio capable of producing partial oxidation products in said catalyst bed under partial oxidation conditions, wherein said modification of said ignition feed is conducted to accomplish a predetermined heatup rate of said catalyst bed, and wherein the amount of diluent present during said modification is sufficient to control the adiabatic reaction temperature.
