Objective:
The objective of this research project is to develop a novel, low-cost process for mercury emissions control through manipulation of homogeneous mercury chemistry.
Progress Summary:
During Year 1 of the project, the experimental effort focused on the redesign of an existing flow reactor to accommodate gas injection as specified in the proposal. Examination of appropriate homogeneous kinetic models for mercury oxidation also was initiated. A detailed understanding of the chemicals and the appropriate temperature range for their injection is essential to determine the appropriate additive(s) needed to modify mercury chemistry.
Future Activities:
Efforts in Year 2 of the project will focus on detailed chemical kinetic calculations of mercury chemistry pending addition of a postdoctoral scientist to the project team, and on experiments conducted at both the Connecticut (bench scale flat flame) and Utah (laboratory scale furnace) facilities.
