Abstract
Gas adsorption is an energetically attractive alternative to distillation for a number of industrial separations, but its efficiency can be impaired by degradation of the adsorbent due to coking or hydrothermal ageing. Comprehensive collaborative experimental studies of laboratory and industrial samples have illumated the mechanisms and influence of both coking and hydrothermal ageing, as well as the process conditions under which these effects can be minimised. Thermal swing adsorption processes offer good separations in many instances, but are dependent for their energy efficiency on proper choice and operation of the adsorption, hot desorption and cooling steps. In this work, new models have led to the concepts of reversal temperature and guillotine effect which permit these systems to be operated to new levels of thermal efficiency. The benefits of less frequent regeneration, and in some cases the elimination of an unnecessary thermal process step, promise significant energy savings.
