Absorption of hydrogen sulfide on starting and modified carbons produced from technical-grade lignin

Absorption of hydrogen sulfide on starting and modified carbons produced from technical-grade lignin Processes in which hydrogen sulfide admixtures (from a 1% H2S + 99% Ar mixture) are removed by sorption on starting carbons and those modified with alkali metal ins of various sizes, made from technical-grade lignin, and hydrogen sulfide is eliminated by catalytic oxidation of H2S with oxygen were studied. The factors determining the absorption capacity of the carbons and their catalytic activity in oxidation of hydrogen sulfide were determined: these are, in the first place, presence of water in the pore space and in the hydration shell of modifying ions, size of these ions, and experimental temperature. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Applied Chemistry Springer Journals

Abstract

Processes in which hydrogen sulfide admixtures (from a 1% H2S + 99% Ar mixture) are removed by sorption on starting carbons and those modified with alkali metal ins of various sizes, made from technical-grade lignin, and hydrogen sulfide is eliminated by catalytic oxidation of H2S with oxygen were studied. The factors determining the absorption capacity of the carbons and their catalytic activity in oxidation of hydrogen sulfide were determined: these are, in the first place, presence of water in the pore space and in the hydration shell of modifying ions, size of these ions, and experimental temperature.
