摘要:Methods for the synthesis of graphene, and more particularly the method of synthesizing graphene by flash Joule heating (FJH). Such methods can be used to synthesize turbostratic graphene (including low-defect turbostratic graphene) in bulk quantities. Such methods can further be used to synthesize composite materials and 2D materials.

标 题 :Controlling synthesis of metal sulfide catalysts
发明人：ANAND MADHU
权利人:CONOCOPHILLIPS CO
摘要:Methods and apparatus relate to catalysts and preparation of the catalysts, which are defined by sulfides of a transition metal, such as one of molybdenum, tungsten, and vanadium. Precipitation forms the catalysts and occurs in a slurry media in which the pH is adjusted. Exemplary uses of the catalysts include packing for a methanation reactor that converts carbon monoxide and hydrogen into methane.

摘要:In an improved process for synthesizing a cobalt-molybdenum sulfide catalyst from a catalyst precursor, heat the catalyst precursor in an inert gaseous atmosphere for a first period of time at a first temperature within a range of from greater than 250° centigrade to less than or equal to 450° centigrade and then for a second period of time at a second temperature within a range of from 450° centigrade to less than 600° centigrade.
