ABSTRACT:
A catalytic filtration device for separating a particulate-containing feed stock into a filtrate and a particulate-containing filter cake, having a monolith of porous material containing a plurality of passageways extending longitudinally from an inlet end face to an outlet end face, having a plurality of plugs in the ends of the passageways at the inlet end face and at the outlet end face to prevent direct passage of the feed stock through the passageways from the inlet end face to the outlet end face; a microporous membrane selected to separate the feed stock into a filtrate and particulate-containing filter cake, the membrane applied to at least the wall surfaces of the passageways open at the inlet end face and of mean pore size smaller than the mean pore size of the porous material; the device regenerable by withdrawal of the filter cake from the inlet end face of the device; and a catalyst applied to the device for catalyzing a reaction in the filtrate as it passes through the device. The catalytic filtration device suitable for use for catalyzing a gas phase reaction. Methods for forming and using the catalytic filtration device.
