摘要： Chemical processes are disclosed that act to both regenerate and create new catalyst for iron salt catalyzed Kharasch coupling reactions during the process of creating halogenated hydrocarbons. Such processes include loading a reactor with a quantity of Fe(0) metal such as iron wire, supplying CCl4 to the reactor, supplying a phosphate compound to the reactor, supplying an alkene to the reactor, and supplying a carbonyl of Fe(0) to the reactor.

摘要： Disclosed herein is a very efficient method to make 5-(alkoxycarbonyl)furan-2-carboxylic acids (ACFC) from feedstocks comprised of furoates. When a feedstock comprised of methyl 5-methylfuran-2-carboxylate (MMFC) is used a product comprised of (5-(methoxycarbonyl)furan-2-carboxylic acid (MCFC) is obtained in high yield.

摘要： The present invention relates to the process for the scalable production of Fe3O4/Fe, Sn & Zn doped graphene nanosheets from a naturally abundant seaweed resources such as Sargassum tenerrimum, Sargassum wighti, Ulva faciata, Ulva lactuca and Kappaphycus alvarezii. The granules remained after the recovery of liquid juice from the fresh seaweeds were utilized as a raw material and a deep eutectic solvents (DESs) generated by the complexation of choline chloride and FeCl3, ZnCl2 and SnCl2 were employed as template as well as catalyst for the production graphene nanosheets functionalized with metals. Pyrolysis of the mixture of seaweed granules and DES at 700-900° C. under 95% N2 and 5% H2 atmosphere resulted formation of metal doped graphene sheets with high surface area (120-225 m2·g−1) and high electrical conductivity 2384 mS·m−1 to 2400 mS·m−1. The nanosheets thus obtained could remove substantial amount of fluoride from fluoride contaminated drinking water (95-98%).

摘要： A sorbent composition that is useful for injection into a flue gas stream of a coal burning furnace to efficiently remove mercury from the flue gas stream. The sorbent composition may include a sorbent with an associated ancillary catalyst component that is a catalytic metal, a precursor to a catalytic metal, a catalytic metal compound or a precursor to a catalytic metal compound. Alternatively, a catalytic metal or metal compound, or their precursors, may be admixed with the coal feedstock prior to or during combustion in the furnace, or may be independently injected into a flue gas stream. A catalytic promoter may also be used to enhance the performance of the catalytic metal or metal compound.
