CATALYTIC HYDROTREATING OF HYDROCARBONS WITH CATALYST REGENERATION

摘要

CATALYTIC HYDROTREATING OF HYDROCARBONS WITH CATALYST REGENERATION A catalyst regeneration process is described for hydrotreating catalysts. The regeneration is carried out by passing a product gas stream from a catalytic hydrotreating operation over a catalyst fouled by carbonaceous or coke deposits. The product gas stream is utilized in the form in which it is separated from the hydrotreating operation and includes hydrogen, light hydrocarbons and a sulphurous component such as hydrogen sulphide. This provides an inexpensive regenerating technique which keeps the catalyst in its operational sulphided state throughout the regeneration.
