Development of advanced hot-gas desulfurization sorbents

PDF Version Also Available for Download.

Description

The objective of this study is to develop hot-gas cleanup sorbents for relatively lower temperature application, with emphasis on the temperature applications, with emphasis on the temperature range from 343--538 C. A number of formulations will be prepared and screened for testing in a 1/2-inch fixed bed reactor at high pressure (1 to 20 atm) and high temperatures using simulated coal-derived fuel-gases. Screening criteria will include, chemical reactivity, stability, and regenerability over the temperature range of 343 C to 538 C. Each formulation will be tested for up to 5 cycles of absorption and regeneration. To prevent sulfation, catalyst additives ... continued below

A number of formulations will be prepared and screened for testing in a 1/2-inch fixed bed reactor at high pressure (1 to 20 atm) and high temperatures using simulated coal-derived fuel-gases. Screening criteria will include, chemical reactivity, stability, and regenerability over the temperature range of 343 C to 538 C. Each formulation will be tested for up to 5 cycles of absorption and regeneration. To prevent sulfation, catalyst additives will be investigated, which would promote a lower ignition of the regeneration. Selected superior formulation will be tested for long term (up to at least 30 cycles) durability and chemical reactivity in the reactor. Zinc oxide based sorbents were prepared and characterized as fresh, sulfided, and regenerated sorbents. Results are presented.
