▎ 摘　　要

NOVELTY - The method comprises: contacting carbon including graphene and a promoter consisting of an elemental halogen, a group V halide, a group VI halide, and/or a hydrohalide to form a promoted sorbent particulate; modifying edge structures of the graphene of the carbon for forming carbocations for promoted sorbent to accept electrons from atoms of mercury; and contacting a mercury containing gas stream and the promoted sorbent particulate with an alkaline material for forming a stabilized mercury sorbent particulate from the gas stream. The promoter is in gaseous form or in an organic solvent. USE - The method is useful for separating mercury from a mercury-containing gas stream such as a product of coal or petroleum combustion (all claimed), gas from waste incineration, product gas from gasification, and gases from mineral processing, metal refining, retorting, cement manufacturing, chloralkali plants, dental facilities and crematories. ADVANTAGE - The method is capable of economically, time-effectively and efficiently separating the mercury from the effluent gases. DESCRIPTION OF DRAWING(S) - The diagram shows a flow diagram of a method for preparing promoted carbon sorbents.
