摘要
(IN201617031177) A method of reducing the amount of carbon monoxide present during the metal reduction step of start up thus maintaining metal dispersion and improving the metal reduction and catalyst yields.  Carbon monoxide formation is minimized during the start up procedure and during the initial catalyst dryout phase in a hydrogen containing atmosphere gas is purged from the reactor system either continuously at constant pressure or by a series of pressure/depressure cycles to remove carbon monoxide.  The purging is conducted at temperatures of about 30 500°C and pressures of about 90 5 000 kPa(g) ( 0.9 50 bar(g)).  In this temperature range carbon monoxide absorbed to the surface of the metal will desorb into the hydrogen containing atmosphere and can be removed from the system along with carbon monoxide present in the atmosphere through the purging.
