摘要

Abstract

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

+ C

) yield in the PDP of ethane. At ideal mixing conditions

the C

yield is 75.3% without steam addition and it is 82.9% at steam addition ratio of

=1.4. In comparison

the C

yield in an FIB reactor is 62.4% without steam addition and it increases to 78.5% with steam addition (

=1.4). The requirement of high mixing efficiency is diminished by steam addition

which is favorable for reactor scale-up.
