Once adsorption process is over adsorbent is to be discarded as waste. Generation of waste adsorbent is a serious environmental problem. Adsorbents can be regenerated and put to reuse in the same process line. Steam is well known in process industry and can be utilized for regeneration of spent adsorbents. Use of steam for regeneration has multiple benefits however regeneration as a whole process is less studied. This paper reviews the utilization of the steam for regeneration of adsorbents with special reference to technical and experimental aspects
