An attrition-resistant zinc titanate sorbent for sulfur. [Quarterly] technical report, December 1, 1993--February 28, 1994

In the continuing search for good sorbent materials to remove sulfur from hot, coal-derived gases, zinc titanate sorbents have shown great promise. The objective of this project is to extend the effort started last year on increasing the strength and durability of zinc titanate sorbents with little or no loss in chemical reactivity.. The principle is to contain Zn{sub 2}TiO{sub 4} in a structural matrix of excess TiO{sub 2}. A fluidized bed test was completed this quarter on the second promising formulation selected last year. The results showed its chemical reactivity to increase with each of the ten test cycles. While the breakthrough times were somewhat shorter than for the first formulation tested, the second formulation`s attrition resistance was outstanding. On another task in the project, experiments are underway to develop improved sorbent regeneration procedures.
