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.

In this review, the recent developments of major kinds of water-tolerant solid acids including zeolite, mesoporous silica, metal organic framework-based catalyst, magnetic nanoparticles, and polymeric catalyst are discussed in detail. Special attention has been paid to understand the role of hydrophobicity, acid strength, and structure of water-tolerant solid acids in catalytic performance and their stability. From the literature survey, it is found that despite the modified zeolites have a water contact angle as large as 160°, but their acid strength need to be improved and their small micropore sizes restrict their use in catalyzing the esterification of bulky molecules. In contrast, solid acids with abundant acid sites, suitable hydrophobicity, and abundant mesopores or macropores usually exhibit high activity and reusability. Among all the known solid acids, polystyrene-supported acidic ionic liquid catalysts (PS-CH<sub>2</sub>-[SO<sub>3</sub>H-pIM] [HSO<sub>4</sub>]) show a high yield of n-butyl acetate with 99.1% and high reusability of 13 times, which is a breakthrough over the traditional.
