Abstract
In the isobutene synthesis process, coupling reaction and separation improves
isobutene production and selectivity, reduces operation cost and lets to
produce hydrogen.
Authors focus on the steady state optimization
of isobutane dehydrogenation in hydrogen-permselective Pd/Ag based membrane
reactors. They model the membrane reactors heterogeneously based on the mass
and energy conservation laws at steady state condition.
They employ genetic algorithm to optimize the
operating condition of membrane reactors.
They compare optimization results of membrane reactors with conventional
adiabatic reactors at the same catalyst loading.
