Development Of A Catalytic Membrane Reactor For The Production Of Ethylene Using Oxidative Coupling Of Methane (Oem).
PhD thesis, Perpustakaan Hamzah Sendut.
Abstract
A catalytic membrane reactor resembles shell and tube heat exchanger integrated with
a tubular ceramic membrane was developed for the application in oxidative coupling of
methane (OCM) reaction. A 3-components catalyst system (Na-W-Mn/Si02) was used
to study the OCM reaction in a packed bed catalytic reactor. The effects of various
operating parameters were studied using design of experiments method. The
interaction effects of each parameter were obtained and response surface
methodology coupled with central composite design was applied in determining the
optimum condition. The predicted optimum condition of temperature 850oe, gas hourly
space velocity at 23,947cm3/g.hr, catalyst pretreatment period of 2 hrs, CH" to O2 ratio
7 and dilution ratio 0.2 gave 40.55% methane conversion, 79.51 % C2+ selectivity and
32.24% C2+ yield. The experimental value of with 43.05% methane conversion, 70.62%
C2+ selectivity and 30.40% C2+ yield was obtained at an optimum condition.
