ABSTRACT

In this chapter, an attempt to fabricate a catalytic membrane and membrane reactor for the removal or recovery of elemental sulfur using the Claus reaction is successfully completed and vital conclusions drawn in four major segments of the entire work: (a) fabrication, characterization, and optimization study of a low-cost ceramic support membrane; (b) synthesis and characterization of a catalyst; (c) fabrication and characterization of a low-cost catalytic membrane; (d) performance of a catalytic membrane and membrane reactor. Despite the progress recognized in this area, further advances must expect the development of more stable and affordable catalytic membranes and membrane reactors. The probable benefits of such advances in the field of catalytic membranes and membrane reactors are significant factors for possible large-scale applications in the oil and petrochemical industries. For this reason, the authors have carefully designed and analyzed catalytic membranes and membrane reactors to evaluate their potential advantages over the conventional process currently in operation. On account of high operating and manufacturing costs, the proposed scheme of using a catalytic membrane reactor for sulfur recovery offers low capital investment and operating, manufacturing, and maintenance costs.
