摘要:
A method of removing a catalyst used for catalytic reactions of hydrocarbons from a reaction system for exchange or otherwise comprising treating the catalyst with water or a mineral oil in the presence of a surface active substance or both a surface active substance and a chelating agent to wet the catalyst. This method ensures a safe and simple removal of the catalyst without involving dust scattering, spontaneous combustion or generation of sulfur dioxide gas.
摘要:
A method of softening or loosening caked catalyst pellets used for the desulfurization of a residual oil regardless of the sizes and shapes of the catalyst pellets and without the need of mechanically crushing the caked catalyst comprising contacting the caked catalyst with a washing oil containing an organic amine and/or ammonia gas absorbed therein.

A plurality of fuel nozzles X1 and X2 in combustor X are supplied with fuel gas from a fuel gas system and fuel oil from a fuel oil system, respectively. Gas turbine operation is performed with fuel being changed over to either gas or oil. Fuel oil distribution control system A controls oil flowing into a plurality of fuel pipings. When oil is changed over to gas, fuel oil purge system B is supplied with air of an appropriate temperature and pressure from purging air supply system C. This air flows into fuel oil pipings and nozzles X2 for purging residual oil therein. Fuel nozzle wash system D is supplied with water by-passing from a wash water tank for compressor washing. This water flows through nozzles X2 for washing thereof.
