Bad Grading/Refining
CGS Series of Active Rings

HT-10R

HT-10R- are inert rings used for grading purposes in traditional hydrotreating or filter reactor service. They range in size from 3.2 – 9.0mm and are made or high duration and strength.

HT-80R

a top layer bed grading ring with MoO3 only promotion for all types of hydroprocessing and hydrotreating applications where mild HDS activity is required.

HT-82/83/84R

active NiMo promoted rings have been specially developed by UNICAT for those hydro-processing applications where controlled olefin saturation within the bed grading is of critical importance to mitigate uncontrolled polymerization and or thermal coking.

HT-86R

is a standard hydrodesulphurization and nitrogen removal, NiMo promoted, top layer bed grading ring catalyst for use in all types of hydroprocessing and hydrocracking operations.

HT-88R

an active, nickel based, Arsine removal, top layer grading ring for use in of hydroprocessing applications where pressure drop minimization and metal trapping are required.

HT-89R

an active, NiMo based ultra-high surface area, Si removal grading ring for operation in top layer of Hydro Processing applications where pressure drop alleviation and Si trapping is required. HT-89R utilizes very high surface area carrier technology with metal impregnation to maximize Si trapping in the shape of active high void rings.

HT-90

an active NiMo based high pore volume type Metal Removal type ring for operation in top layer of Hydroprocessing applications where pressure drop alleviation and Ni/V/Fe trapping is required. It utilizes large pore volume technology with metal impregnation to maximize Ni/V/Fe trapping in the shape of active high void rings.

HT-99R

an inert, ultra high surface area, alumina based silica removal grading ring for operation in the top layer of hydroprocessing applications, where pressure drop alleviation and silica removal is required. HT-99R is an excellent value on a cost per pound of silica removed basis, since HT-99R utilizes very high surface area carrier technology to maximize silica removal instead of more costly nickel promotion.
