Materials and methods for inhibiting the formation of filamentous coke on heated metal surfaces. Organoselenium compounds, including diarylselenides, diaryldiselenides, alkylarylselenides, and alkylaryldiselenides, are employed as hydrocarbon feedstock additives or as hydrocarbon fuel additives to inhibit filamentous coke formation on hydrocarbon processing systems, including reactors, furnaces, engines and parts thereof and in particular to inhibit filamentous coke formation on heat-exchangers in such systems.

The invention provides improved burners, combustion apparatus, and methods for carbon nanomaterial production. The burners of the invention provide sooting flames of fuel and oxidizing gases. The condensable products of combustion produced by the burners of this invention produce carbon nanomaterials including without limitation, soot, fullerenic soot, and fullerenes. The burners of the invention do not require premixing of the fuel and oxidizing gases and are suitable for use with low vapor pressure fuels such as those containing substantial amounts of polyaromatic hydrocarbons. The burners of the invention can operate with a hot (e. g. , uncooled) burner surface and require little, if any, cooling or other forms of heat sinking. The burners of the invention comprise one or more refractory elements forming the outlet of the burner at which a flame can be established. The burners of the invention provide for improved flame stability, can be employed with a wider range of fuel/oxidizer (e. g.

The invention relates to catalysts and catalytic methods for selective oxidation of hydrogen sulfide (HS) in a gas stream containing one or more oxidizable components other than HS to generate sulfur dioxide (SO), elemental sulfur (S) or both without substantial oxidation of the one or more oxidizable components other than HS. The catalysts and methods herein are useful, for example, for the selective oxidation of HS to SO, sulfur or both in the presence of hydrocarbons, hydrocarbon oxygenate, sulfur-containing organic compounds, aromatic hydrocarbons, aliphatic hydrocarbons, carbon dioxide, hydrogen or carbon monoxide.

Apparatus and method are described for enhancing performance of an alcohol fueled engine during cold conditions, with such enhancement being particularly effected by generation of ether to assist cold operation including starting and/or to achieve reduced emissions during cold running. Dimethyl ether is generated by catalytic dehydration of vaporized methanol using a catalyst, preferably fluorinated alumina. Apparatus is disclosed for generating dimethyl ether on board as needed for immediate mixing with combustion air and methanol and/or for storage to enable later mixing of the dimethyl ether with combustion air and methanol to effect subsequent cold starts and/or cold running operations.

A wearable breathing apparatus includes a thermal capacitor that a user inhales and exhales through. Inhaled air is cooled as it passes through the thermal capacitor, and exhaled air cools the material of the thermal capacitor for the next breathing cycle. The breathing apparatus may be used by a firefighter, for example, as a lightweight apparatus to enable the firefighter to safely breathe dangerously heated air, for example while in a fire shelter, that may otherwise cause injury to the user. The breathing apparatus advantageously does not require external power for cooling. The thermal capacitor may also be used as a part of a rebreather that uses a scrubber that removes carbon dioxide from exhaled air, for rebreathing. Further, the thermal capacitor may be used for other purposes, such as in recirculation of building air.
