Subtask 2.8 - Control of Trace Elements in Gasification Systems

PDF Version Also Available for Download.

Description

Detailed investigations were carried out to investigate the removal of mercury using a variety of substrates at elevated temperature under reducing conditions. Sorbents tested mainly comprised 6A, 7A, 1B, 2B, and metals from the periodic table. The new high-surface halogen-treated carbon sorbents performed exceptionally well on the bench scale at relatively high temperatures (400 C). The new sorbents could be incorporated into a gas cleanup technology for fuel gas, where the gas is cooled to medium temperatures. Other work in this task focused on halogen-containing sorbents prepared on a carbon support. Similar sorbents had been previously found to be superior ... continued below

Sorbents tested mainly comprised 6A, 7A, 1B, 2B, and metals from the periodic table.

The new sorbents could be incorporated into a gas cleanup technology for fuel gas, where the gas is cooled to medium temperatures. Other work in this task focused on halogen-containing sorbents prepared on a carbon support. Similar sorbents had been previously found to be superior for mercury in flue gas. All granular sorbents were conducted in fixed beds heated at 350 and 400 C with 10 vol% hydrogen in a nitrogen stream containing 34.8 {mu}g/m{sup 3} of Hg{sup 0}.
