TLDR
In this paper, a corrugated stainless steel sheet and a flat steel sheet are sandwiched together and wound spirally so the corrugations form a plurality of small gas flow passages connecting the converter inlet with the converter outlet.
Abstract
A corrugated stainless steel sheet and a flat stainless steel sheet are sandwiched together and wound spirally so the corrugations form a plurality of small gas flow passages connecting the converter inlet with the converter outlet. Alumina coatings on the sheets electrically insulate the sheets from each other and a finely divided catalyst is distributed on the alumina coatings. Electrical energy flows through the sheets to heat the catalyst to operating temperature.
