◼PRODUCT DESCRIPTION

GR-901catalyst is a Tio2-based sulfur recovery catalyst that is resistant to sulfation. compared with the GR203-based catalyst currently being promoted in industry, this catalyst has the following characteristics.

(1)It has higher catalytic activity for the hydrolysis reaction of organic sulfides and theclaus reaction of H2sand so2, almost reaching thermodynamic equilibrium.

(2)It is not sensitive to"leaking o2"poisoning. The tolerance to"leaking o2"poisoning is 2000ppm for the hydrolysis reaction and up to10000ppm for the claus reaction. once the influence of high concentration o2i selim i noted, the activity is almost completely restored. (3)To achieve the same conversion rate level,a shorter contact time of about3seconds is allowed,which is equivalent to a space velocity of1000h-1to1200h-1, so the reactor volume can be reduced.

GR-901catalyst can be used in the full bed of any primary reactor of the sulfur recovery unit or in layered loading with other catalysts of different functions or types. when used in layered loading, the GR-901catalyst can be loaded in the lower part of the first reactor bed where the temperature is higher, accounting for about1/3to1/2of the total volume of the bed, to facilitate the hydrolysis reaction of org onic sulfides.
