Emphasis is placed on the use of resin as a catalyst rather than on reactions. Various aspects of resin catalysis, such as types of reactions where resin can be used, the physical form of resin and activity, and issues pertaining to its application as a catalyst are discussed. Advantages and disadvantages of resins as catalyst for different types of reactions are highlighted. Aspects like reactor configurations, selection of resin, process integration, process separations and the environmental impact of using resins as catalysts are also included. Possible future developments in the ion exchange catalysis area are also highlighted.1 aBhandari, V., M.1 aSorokhaibam, L., G.1 aRanade, V., V.  uhttps://library.ncl.res.in/content/ion-exchange-resin-catalyzed-reactions-overview02147nas a2200229   4500008004100000245011600041210006900157260000800226300001200234490000800246520137700254653000901631653001401640653001401654653002201668653002001690100002201710700002101732700002201753700001901775856012301794       2017                        eng d00aDeveloping techno-economically sustainable methodologies for deep desulfurization using hydrodynamic cavitation0 aDeveloping technoeconomically sustainable methodologies for deep  cDEC  a482-4900 v2103 aThe present work, for the first time, describes the efficacy of the cavitation process and compares the cavitation yield for two types of cavitation devices-one employing linear flow for the generation of cavities and other employing vortex flow. The process involves pre-programmed mixing of the organic and aqueous phases, and can be carried out using simple mechanical cavitating devices such as orifice or vortex diode. The process essentially exploits in situ generation of oxidising agents such as hydroxyl radicals for oxidative removal of sulfur. The efficiency of the process is strongly dependent on the nature of device apart from the nature of the organic phase. The effects of process parameters and engineering designs were established for three organic solvents (n-octane, toluene, n-octanol) for model sulfur compound-Thiophene. A very high removal to the extent of 95% was demonstrated. The results were also verified using commercial diesel. The cavitation yield is significantly higher for vortex diode compared to the orifice. The process has potential to provide a green approach for desulfurization of fuels or organics without the use of catalyst or external chemicals/reagents apart from newer engineering configurations for effective implementation of hydrodynamic cavitation in industrial practice and also appears to be economically sustainable.10aFuel10aOxidation10aPetroleum10aPollution Control10aSulphur Removal1 aSuryawanshi, N.B.1 aBhandari, V., M.1 aSorokhaibam, L.G.1 aRanade, V., V.  uhttps://library.ncl.res.in/content/developing-techno-economically-sustainable-methodologies-deep-desulfurization-using02212nas a2200217   4500008004100000022001400041245012600055210006900181260000800250300001600258490000700274520146300281653001501744653001301759653001401772653001901786653002301805100001701828700002101845856012801866       2022                        eng d  a1735-147200aDeveloping spherical activated carbons from polymeric resins for removal of contaminants from aqueous and organic streams0 aDeveloping spherical activated carbons from polymeric resins for  cOCT  a10021-100400 v193 a<p>
	Spherical activated carbons from polymer resin were developed with metal modifications, before/after carbonization using copper and nickel, for gradation of zeta potential (-5.01 to 8.64 mV) and high metal loading (up to 12.3%). The materials provide improved removal of various contaminants from aqueous and organic streams-removal of bacteria from water and sulfur removal from fuel. The metal-modified spherical activated carbons were highly effective for removal of both gram-negative E. coli and gram-positive S. aureus bacteria. The copper-modified spherical activated carbon could eliminate 99.9-100%, both bacterial content proving efficacy in water disinfection with a very high rate similar to 1.33 x 10(5) (CFU/ml.s). The zeta potential has significant impact with higher disinfection for high values; similar to 10-15% disinfection can be improved up to 100% for zeta potential changes from -5 to 8.6 mV. Kinetics of disinfection was studied by accounting for zeta potential in the conventional rate model, and the efficacy of both the models was compared. The fit of revised model was excellent. The spherical activated carbons can be useful for removal of slightly polar contaminants from organic streams and a high capacity of 12.8, 20 and 28 mgS/g for thiophene, benzothiophene and dibenzothiophene, respectively. The developed materials can provide useful applications in the area of environmental pollution control. [GRAPHICS] .</p>
