摘要:A system and method are presented for the large scale synthesis of metal cyanometallates (MCMs). First and second precursor solutions are added to a main reactor, where the first precursor includes M1 metal cations. The second precursor solution includes A X′ M2(CN) Z′ , where M1 and M2 are from a first group of metals and A is from a second group of metals including alkali or alkaline earth metals. In response to stirring the first and second precursors, MCM particles are formed with the formula A X M1 N M2 M (CN) Z .d[H 2 O] ZEO .e[H 2 O] BND , in solution. In response to aging in the secondary reactor, the size of the MCM particles is increases. The aged MCM particles in solution are then transferred to a separation tank, where the aged MCM particles are filtered from the solution and collected. The solution reclaimed from the separation tank back is added back into the main reactor.

标题 :Leached catalyst for ammonia synthesis
发明人：VANDERSPURT THOMAS H; RICHARD MICHAEL A; MONTAGNA ANGELO A
权利人:EXXON RESEARCH ENGINEERING CO
摘要:An improved catalyst for the synthesis of ammonia is described wherein a promoted iron-derived, pre-reduced catalyst is oxidatively leached with a neutral aqueous solution of potassium cyanide. Preferably an organic carboxylic acid such as citric acid is added to the aqueous solution to maintain the pH at about neutral. The resulting leached catalyst has a markedly higher activity than the unleached catalyst. The leached catalyst may be contacted with a cobalt complex or a nickel salt to incorporate cobalt or nickel therein which catalysts are also useful for ammonia synthesis.

发明人：SONG JIE; LU YUHAO; WANG LONG
权利人:SHARP LAB OF AMERICA INC; UNIV TEXAS
摘要:A method is provided for synthesizing metal cyanometallate (MCM). The method provides a solution of A X M1 Y (CN) Z ; where “Aâ€? is selected from a first group of metals and M1 is selected from a second group of metals. The method adds a material including M2 to the solution to form a liquid phase material that may be either a suspension or a solution. M2 is selected from the second group of metals. The method adds acid to the liquid phase material. The addition of acid to the liquid phase material decomposes the M2 material into M2-ions. Simultaneous with the addition of the acid, a precipitate of A N M1 P M2 Q (CN) R .F H 2 O is formed, where N is in a range of 1 to 2. A variation of the above-described synthesis method is also provided.
