Abstract: A two or particularly three-phase process, and corresponding apparatus, desulfurizes sour hydrocarbon gas, e.g., natural gas, generally better than known, using a fixed-bed, two-phase processes in terms of the amount of H2S scavenged and the breakthrough time of H2S. The three-phase process is effective in scavenging H2S at ambient temperature and pressure, using a copper salt catalyst impregnated on alumina or other generally inert support, which is regenerable.

Abstract: A method for preparing multi-wall carbon nanotubes comprising atomizing a precursor solution comprising an aromatic hydrocarbon and a carrier gas. The mixture is then injected through an ultrasonic atomization system to form atomized precursor droplets. Then by injecting the atomized precursor droplets from the top of a vertical chemical vapor deposition reactor, the droplets can then react with a reaction gas in the reactor vessel to form a film that adsorbs to a growth surface in the reactor vessel. Layer by layer multi-wall carbon nanotubes are formed. This method is repeated to form layers of the multi-wall carbon nanotubes. The nanotubes formed have an outer diameter of 10 nm-51 nm and a length to diameter aspect ratio of 7200-13200.

Abstract: A vertical chemical vapor deposition (CVD) reactor and a method for synthesizing metal oxide impregnated carbon nanotubes. The CVD reactor includes a preheating zone portion and a reaction zone portion, and preferably an additional cooling zone portion and a product collector. The method includes (a) subjecting a liquid reactant solution comprising an organic solvent, a metallocene, and a metal alkoxide to atomization in the presence of a gas flow comprising a carrier gas and a support gas to form an atomized mixture, and (b) heating the atomized mixture to a temperature of 200° C.-1400° C., wherein the heating forms a metal oxide and at least one carbon source compound, wherein the metallocene catalyzes the formation of carbon nanotubes from the at least one carbon source compound and the metal oxide is incorporated into or on a surface of the carbon nanotubes to form the metal oxide impregnated carbon nanotubes.
