摘要:A method of forming polycrystalline diamond includes forming metal nanoparticles having a carbon coating from an organometallic material; combining a diamond material with the metal nanoparticles having the carbon coating; and processing the diamond material and the metal nanoparticles having the carbon coating to form the polycrystalline diamond. Processing includes catalyzing formation of the polycrystalline diamond by the metal nanoparticles; and forming interparticle bonds that bridge the diamond material by carbon from the carbon coating.

标题:Process for preparing alkanols and esters from synthesis gas
发明人：LIN JIANG-JEN
权利人:TEXACO INC
摘要:This invention concerns a process for making alkanols and esters which comprises reacting a mixture of CO and H2 at a pressure of about 500 psig or greater and at a temperature of at least 150 DEG C. in the presence of a catalyst system comprising a ruthenium-containing compound, a second metal from Group IVB, VB, or VIB, consisting of a zirconium, titanium, vanadium or chromium-containing compound and a quaternary phosphonium salt, in the presence of an inert, oxygenated solvent.
