Abstract
Systems and methods are provided for activation of noble metal catalysts that are supported on siliceous supports. The activation method can include limiting the amount of water vapor pressure and/or the time of exposure to the water vapor pressure during heating of the catalyst at temperatures of 50° C. or less. This can be achieved by introducing heated gas into multiple reactors of a multi-reactor system at the same time. A suitable system for introducing heated gas into multiple reactors can correspond to a system with multiple heated hydrogen lines for delivery of heated hydrogen to a plurality of reactors within a multi-reactor system.
