Abstract

In a process for the hydrocatalytic refining of waxes or lubricating oils at elevated pressure in the presence of hydrogen and a hydrogenation catalyst, in which the feedstock is changed from a microcrystalline to a crystalline wax or from a solvent-treated to a non-solvent-treated grade of lubricating oil, the changeover is effected by discontinuing the passage of the existing feedstock while continuing the passage of hydrogen, substituting an alternative petroleum hydrocarbon feedstock, raising the temperature to above that used for the first-mentioned feedstock up to a maximum of 750 DEG F. for a period of from 5 to 50 hours and then lowering the temperature and commencing the processing of a crystalline wax or non-solvent-treated grade of lubricating oil. The alternative feedstock may be the feedstock which is about to be processed or a "buffer" stock such as a gas oil. Preferably, the alternative feedstock is processed at a lower pressure than the original or final feedstock.
