Due to the worse conditions of the crude oils feed into the refineries, heavy and non-conventional crude oil increased to higher level, this is a big challenge to the hydro-processing technology and catalyst, to avoid catalyst poisoning and mitigating the pressure drop and eliminate the contaminants.
SINOCATA developed serial grading catalyst solutions which help to extend the life cycle of the hydro-processing unit. For active grading catalyst, SINOCATA has hollow ring, trilobe, quadralobe shaped products with Ni, Mo, NiMo, CoMo impregnated.
Application
GCR Serial is a NiMo/CoMo hollow rings with mild activity designed which is used as active top bed grading media in a variety of hydroprocessing unit applications. The products has very excellent physical strength, also provides high void space for particulate trapping. These rings can be used along with GCT serial trilobes, GCQ serial quadralobes grading catalyst which are typically loaded above the main bed catalyst and for better flow distribution. GCR Seria’s hydrogenation activity reduces the rate of bed fouling caused by coke deposition compared to inert topping media and also reduces the amount of polymerization reactions in olefinic feeds compared to standard hydrotreating catalysts and inert materials.
SINOCATA offer the size 3.2mm, 4.8mm, 6.4mm and 9.0mm for Active Grading Rings which were delivered at very low cost to maximize overall catalyst life cycle.
