AM-99-38 ADVANCED DISTILLATE HYDROPROCESSING ASAT® A TRIFUNCTIONAL HDAR/HDS/HDN CATALYST

Description:

ASAT® is a new distillate hydroprocessing catalyst offering refiners increased options for dealing with present and proposed regulatory requirements of reduced sulfur and aromatics in diesel fuels. Current catalyst options require low sulfur content feed stocks to affect aromatics hydrogenation, usually in a two stage process having deep desulfurization in the first stage. ASAT® is a bimetallic noble metal on zeolite catalyst which can give substantial aromatics reduction, as well as HDS and HDN, in the presence of up to 570 ppm sulfur and up to 233 ppm nitrogen. This paper will discuss the catalyst, operating parameters, and results of a wide range of test conditions.
