Abstract
Compositions and processes for their use as additives for reducing the sulfur content of FCC gasoline employ a support material montmorillonite clay material. A fluid catalytic cracking (FCC) mixture, therefore, is provided comprising an FCC catalyst and separate particles of sulfur reduction additive consisting of porous montmorillonite clay.
Claims (3)
1. A fluid catalytic cracking (FCC) mixture comprising an FCC catalyst and separate particles of sulfur reduction additive consisting of porous montmorillonite clay.
2. The mixture as in claim 1 , wherein the montmorillonite clay has a surface area in the range of 150 m 2 /g to 350 m 2 /g.
3. The mixture as in claim 1 , wherein the montmorillonite clay is calcined in air at 550° C.
