摘要:
Mixed metal oxide catalysts are prepared by combining first nanoscale particles and second nanoscale particles to form a mixture of nanoscale particles and then the mixture is heated to form a mixed metal oxide catalyst. The mixed metal oxide catalysts, which are capable of reducing the concentration of carbon monoxide in the mainstream smoke of a cigarette during smoking, are incorporated into a smoking article component such as tobacco cut filler, cigarette paper and/or cigarette filter material.
摘要:
A smoking article composition and a method of making a smoking article composition and an additive, wherein the additive comprises particles anchored to the cut filler by a metal oxide support. The additive can be formed by combining particles and a metal oxide precursor solution with the smoking article composition. The smoking article composition can comprise tobacco cut filler, cigarette paper and/or cigarette filter material.

Systems and methods are provided that include a heat integrated coal treating system having a two-stage coal treating process. In one embodiment, the two-stage treating process may include an HF reactor and an HNO3 reactor coupled to the nitric acid reactor and having a fluid exchanging heat between the hydrofluoric acid reactor and the nitric acid reactor.
摘要:
A method of continuously removing nitrogen from a blast furnace exhaust stream containing oxygen, nitrogen and unburned hydrocarbons in order to form a supplemental feed to a gas turbine engine containing residual hydrocarbon fuel by first removing entrained solid particulates in the blast furnace exhaust stream to create a substantially particulate-free gas, passing the particulate-free stream through at least one separator bed containing an adsorptive material capable of adsorbing nitrogen from air, adsorbing substantially all of the nitrogen as interstitial nitrogen on solids within the separator bed, feeding non-adsorbed hydrocarbon fuel and oxygen components leaving the separator to a gas turbine engine and removing the adsorbed nitrogen from the separator bed.
摘要:
A system for capturing carbon dioxide is provided including a feed line transporting an exhaust gas, a first separator, a first compressor, a first membrane, a first ejector, a second separator, a second compressor, and a carbon dioxide storage tank. The first membrane is configured to filter the exhaust gas into a retentate stream of exhaust gas and a permeate stream of exhaust gas. The permeate stream of exhaust gas includes a larger amount of carbon dioxide than the retentate stream. The first ejector is configured to compress the permeate stream. The second compressor is configured to further compress the exhaust gas received from the second separator. The carbon dioxide storage tank is configured to receive the exhaust gas from the second compressor. A second membrane can be on the retentate stream of the first membrane, where a second ejector is on the permeate side of the second membrane.
