Procedure for Steam Reforming Catalyst Reduction with LPG Feed
This procedure may be used for the reduction of VULCAN Series Catalysts for the general steam reforming of LPG.
It is strongly advised that this procedure is adopted only where there is no other option available to use hydrogen, a hydrogen-rich gas or natural gas for the reduction stage. Reduction using the cracking of heavier hydrocarbons carries an extreme risk of catastrophic carbon formation in the event of any error in execution of the procedure.
LPG is not normally utilized for steam reforming catalyst reduction although it can be used successfully. Caution is required if heavier hydrocarbons are used for catalyst reduction. Although operators have been able to reduce catalysts by using heavier hydrocarbon cracking, this has only been adopted where no other reductant option is available. The risk of carbon formation greatly increases as the carbon number of the feed increases when the catalyst is in the unreduced state. For the purposes of this procedure, LPG may range from a hydrocarbon mixture which is predominantly propane to one which is predominantly butane.
