Catalytic non-thermal plasma assisted conversion apparatus and method

Abstract

A dielectric barrier discharge plasma reactor and method in which plasma is used to activate difficult-to-activate molecules and the catalyst so that chemical conversion of the activated molecules can occur at reduced temperature and pressure conditions to carry out chemical reactions that ordinarily occur at high temperature and high pressure conditions or otherwise do not occur at all. The dielectric barrier discharge plasma reactor includes a tubular outer ground electrode having an inner surface bounding an interior volume therein, a dielectric electrode coaxially mounted in the interior volume of the tubular outer ground electrode, the dielectric electrode comprising a central electrode in a cylindrical dielectric element, the cylindrical dielectric element having an outer surface in spaced relationship to the inner surface of the tubular outer ground electrode to define an annular fluid flow passage therebetween, and a catalyst material comprising catalyst coated on the inner surface of the tubular outer ground electrode and optionally further comprising catalyst in a catalyst bed in the annular fluid flow passage.
