The auto-thermal reaction of ethanol occurred in the shell side of a palladium membrane reactor in which a Zn-Cu/AlaOs industrial catalyst (MDC-3) was packed with silica powder. Ethanol-water mixture (nH2o/nEioH=l or 3) and oxygen (noa/nEioH=0.2,0.776 or 1.035) are fed concurrently to the shell side. The reaction temperatures were set at 593-723 K and the pijrasures were 3 10 atm.

Low-loaded, organophilic Pd-montmorillonites were shown to exhibit high cis-selectivity in the hydrogenation of 1-phenyl-1-alkynes working with high (=5000) substrate catalyst ratio.402 Studies with respect to the use palladium membrane catalysts403 105 and polymeric hollow fiber reactors406"408 were reported.

Itoh et al(S). studied dehydrogenation of cyclohexane in a palladium membrane reactor containing a packed bed of Pt/Al203 catalyst. The removal of hydrogen from the reaction mixture using the pal dium membrane increased the conversion from the equilibrium value of 18.7% to as high as 99.5%. It was shown that for given rates of permeation and reaction, there is an optimum thickness of membrane, at which maximum conversion is obtained. 

A schematic of a palladium membrane reactor is shown in figure 1. The reversible reaction of 1-butene dehydrogenation occurs on the reaction side of the membrane in which the chrome-alumina catalyst is uniformly packed. The oxidation of hydrogen with oxygen in air occurs in the permeation or separation side on the palladium membrane surface. The...
