摘要：

Hydrogen sulphide (H2S) adsorption capacities on recycled rubber media, tyre-derived rubber particle (TDRP (TM)), and other rubber material (ORM (TM)) have been evaluated. As part of the research, densities, moisture contents, and surface properties of TDRP (TM) and ORM (TM) have been determined. The research team findings show that TDRP (TM) and ORM (TM) are more particulate in nature and not highly porous-like activated carbon. The characteristics of surface area, pore size, and moisture content support chemisorption on the macrosurface rather than physical adsorption in micropores. For example, moisture content is essential for H2S adsorption on ORM (TM), and an increase in moisture content results in an increase in adsorption capacity.
