摘要
In our previous work,a partially decoupled process(PDP)was proposed for efficient conversion of ethane to increase the ethylene yield and a new structural reactor called forward-impinging-back reactor(FIB)was proposed for scale-up.In this work,the influence of changing the composition and temperature of the heat carrier was investigated by simulations with detailed chemistry to further increase of the C_(2)(C_(2)H_(2)+C_(2)H_(4))yield in the PDP of ethane.At ideal mixing conditions,the C_(2) yield is 75.3%without steam addition and it is 82.9%at steam addition ratio of β=1.4.In comparison,the C_(2) yield in an FIB reactor is 62.4%without steam addition and it increases to 78.5%with steam addition(β=1.4).The requirement of high mixing efficiency is diminished by steam addition,which is favorable for reactor scale-up.
