摘要
液化天然气(LNG)是一种重要的清洁化石能源。近年来,液化天然气工业得到了极大的发展,但天然气中的汞在液化工艺过程中却带来了诸多问题,因而对天然气中汞进行有效脱除十分必要。天然气中汞的主要脱除技术是吸附法,脱汞吸附剂主要包括改性活性炭、分子筛、金属硫化物和其他近年来开发的一系列新型吸附剂。
Liquefied natural gas（ LNG） was an important clean fossil fuel. In recent years,the liquefied natural gas（ LNG）industry has got rapid development,but the mercury in natural gas during the natural gas（ LNG） liquefied process brought many problems. Therefore,it was very necessary to remove mercury from natural gas. Mercury in nature gas mainly was removed by adsorption,and the adsorbents included modified activated carbon,molecular sieve,metal sulfide and other series of new developed adsorbents in recent years.
