What is Techniques for Overcoming Sulfur Poisoning of Catalyst Employed in Hydrocarbon Reforming about?

Sulfur poisoning of catalyst is a well-known phenomenon observed during the production of syngas (CO + H 2 ). The presence of traces of sulfur content in the feedstock can drastically reduce the catalyst activity and life. Several measures have been developed over the years to mitigate the catalyst deactivation process due to sulfur poisoning. In this paper, we review literature from 1996-present related to all the developments made for sulfur-resistant systems. The basis of poisoning being the sulfur content in the feedstock, potential fuel-containing feedstocks for syngas production were briefly discussed. The basics of sulfur poisoning mechanisms are also summarized. Then, a framework consisting of sulfur tolerance methodologies were discussed. In particular, we have discussed: (i) catalyst development by altering catalyst composition and support systems, (ii) influence of using catalyst structures, (iii) process modifications and optimization, (iv) desulfurization techniques for removal of sulfur from feed and/or product streams, and (v) effective catalyst regeneration techniques to extend the catalyst life. This review emphasizes the integration of the best set of methods to d
