It is entirely feasible to install titanium-based catalysts in all sections of the Claus reactors; however, the main purpose of using titanium-based catalysts is to promote the hydrolysis of organic sulfur in the primary Claus reactor. The organic sulfur content in the process gas coming out of the primary reactor is already very low, so installing titanium-based catalysts in the other reactors would be a waste, as the cost of titanium-based catalysts is much higher than that of aluminum-based catalysts.

Suppliers of sulfur recovery catalysts can use specialized software such as Sulsim to conduct simulation calculations based on the composition of the acidic gases, operating conditions, and the required overall sulfur recovery rate, thereby recommending the optimal catalyst combination.
Of course, it’s possible to use titanium-based catalysts for everything, but their price is too high, and they also have low strength and tend to become powdered. It is recommended to fill 1/3–1/2 of the volume at the bottom of the reverse side with something other than alumina.
