摘要
Abstract
Sorption-enhanced dimethyl ether synthesis(SEDMES)is a powerful technology to produce dimethyl ether(DME)from residual industrial gas streams or captured CO2 and renewable H2.In situ water removal by zeolites shifts the thermodynamic equilibrium of the reaction towards product formation.Sorption enhancement proved to provide a single-pass CO2 conversion above state of the art values.Building knowledge on prior optimisation of a CO2-H2 feed,this work extends modelling of SEDMES to a design study for four distinct industrial feeds,with progressively higher CO content.The trade-offs between DME productivity and carbon distribution over the products were studied.The impact of process parameters such as cycle duration,feed flow,operating pressure,temperature,reactant stoichiometry,amount of inert gases and the presence of CO was analysed in detail,including the impact of flexible operation and turndown.Results show that higher CO feed concentrations enhance the DME productivity but complicate the purification due to increased CO2 by-product formation.Variations in the feed H2-C ratio affected by-product selectivity,with lower ratios reducing CO2 and methanol formation,potentially simplifying downstream processing.Pressure and temperature were identified as critical design parameters.Higher operating pressures consistently enhanced DME productivity in all cases,while a moderate temperature increase above 250 ℃ proved to be beneficial as well.Moreover,the process demonstrated resilience under lower feed flow conditions(factor 3 in turn down ratio)that could potentially be caused by renewable electricity fluctuations,without compromising the performance.关键词
