Suitable carbonates include, but are not limited to, carbonates of alkali metals and alkaline earth metals, preferably carbonates of calcium and magnesium. Waste products are metal cations and bicarbonate in solution or dehydrated metal salts, which when disposed of in a large body of water provide...
Question: What are the products of electrolysis of water? Electrolysis: Electrolysis is the process by which electrical energy is used to split compounds. The word electrolysis was first introduced to the scientific lexicon by Michael Faraday close to 200 years ago and is still in use. ...
Besides the alkali metals, other metals such as Cu, Zn, Ni, Zr, Mn, and Pt can also be used to modify Fe- based catalysts83. For example, bimetallic Fe–Cu/Al2O3 catalysts can suppress CH4 formation and thus exhibit higher amounts of C2–C7 production compared with pure Fe/Al2O3 ...
Astatine is produced by, e.g., the 209Bi(α,xn)213−xAt reaction where the α-particle is produced by another reaction and sequentially reacts with 209Bi. Although the four elements, Pb, Bi, Po and At, and some others are not SP when strictly speaking, we call all the elements ...

The first route begins with 1-amino-2-methyl-4-bromoanthraquinone, a material marketed by Sandoz Color and Chemical under the tradename AMBAX, or made as in Example I. ##STR16## This material is reacted with a benzylic acid chloride, ##STR17## corresponding to the nonfused pendant arom...
reduction-calcination of the nickel contained therein in order to obtain calcined ore, contacting the calcined ore with an aqueous solution of ammonia containing free sulphur in order to extract useful metals such as nickel therefrom, and the addition of resulting extracted residue to the water. In...
Petroleum makes the world go around. In the realm of global economics and politics, that statement is hard to dispute. Petroleum is uniquely versatile. When wisely handled, it is safe and clean compared to most alternatives. It is still abundant, and it
Water may not easily pass through and penetrate the CaSO4 layers to react with f-CaO grains if the CaSO4 layers are thick and dense [69], [88], [102]. According to Iribarne et al., the reactivity of anhydrite in FBC fly ash is closely related to its thermal history, i.e. when ...
However, the concentrations of alkalis, such as sodium hydroxide and sodium carbonate, lead to higher corrosion, and alkali recovery is a challenging task. Among the pretreatments, LHW stands out for hemicellulose hydrolysis, using water as a reactant without further input of acids/bases. Besides,...
