摘要： Hydrocarbon hydroprocessing using catalysts containing a Group VIB metal and a phosphorus component on a porous refractory oxide is prepared by impregnating support particles with a solution containing (1) phosphorus, and (2) citric acid in a mole ratio to Group VIB metal components of less than 1 to 1, followed by drying and calcining. The catalysts are useful for promoting a number of hydrocarbon hydroprocessing reactions, particularly those involving hydrogenative desulfurization, demetallization and most particularly, denitrogenation.

摘要： A method of stabilizing pyrophoric hydrotreating catalyst drums has been discovered. The dry catalyst is introduced into drums which have been purged with an inert gas such as nitrogen or carbon dioxide. A continuous layer of gelatinized starch is applied to the top of the catalyst, sealing it from air. The drum lid is clamped on and the catalyst is stored or transported. The gelatinized starch seal does not impair the catalyst for regeneration or metals reclaiming.
