LHGS04 de-oxygenation catalyst takes precious metal as active component basis loading on activated alumina carrier, which is mainly used to remove oxygen from hydrogen gas, also for nitrogen, CO, CO2, Argon and inert gas.
Operation for hydrogen gas and Argon gas could be done under normal temperature while space velocity (3~10)×103 h-1 and residual oxygen could be 0.2ppm. For synthesis gas, coal gas and coking dry gas, operation have to be done at temperature 110~140℃, pressure>0.1Mpa, space velocity (1~4)×103 h-1, and residual oxygen could be <1ppm.
