The present invention is one or more processes for producing separable iron and titanium oxides from an ore comprising titanium oxide and iron oxide, comprising: (a) forming agglomerates comprising carbon-based material and the ore, the quantity of carbon of the agglomerates being at least sufficient for forming a ferrous oxide-containing molten slag, at an elevated temperature; (b) introducing the agglomerates onto a bed of carbon-based material in a moving hearth furnace, wherein the carbon-based materials used for both the agglomerates and the bed have a low sulfur content; (c) heating the agglomerates in the moving hearth furnace to a temperature sufficient for liquefying the agglomerates to produce a liquid comprising ferrous oxide-containing slag; (d) metallizing the ferrous oxide of the slag by reaction of the ferrous oxide and the carbon of the carbon bed at a furnace temperature sufficient for maintaining the slag in a liquid state; (e) solidifying the slag after metallization of the ferrous oxide to form a matrix of titanium oxide-rich slag having a plurality of metallic iron granules distributed there through; and (f) separating the metallic iron granules from the slag, the slag comprising greater than 85% titanium dioxide based on the entire weight of the matrix after separation of the metallic iron.

This invention provides a catalyst and a process for the catalytic partial oxidation of a hydrocarbon feedstock by contacting a feed stream including a hydrocarbon feedstock and an oxygen-containing gas with a catalyst in a reaction zone maintained at conversion-promoting conditions effective to produce an effluent stream including carbon monoxide and hydrogen. The process of this invention is characterized by using a porous catalyst containing rhodium, such as rhodium gauze or rhodium felt.

A process for the production of synthesis gas from light hydrocarbons such as methane includes the net catalytic partial oxidation of a hydrocarbon feedstock by contacting a feed stream comprising the hydrocarbon feedstock and an O -containing gas with a catalyst in a reaction zone maintained at conversion-promoting conditions effective to produce an effluent stream of H and CO in a molar ratio of about 2:1. A preferred catalyst used in the process includes at least one catalytically active metal supported on a catalyst support comprising an aluminum-containing, oxide-dispersion-strengthened, alloy that has been treated to provide a protective oxide layer between the support and the catalytically active metal.

A device for determining the level of particulate contamination in a fluid power or lubrication system. Between the inlet and the outlet of the device, working fluid passes through a narrow orifice ( ) defined between a cylindrical spool ( ) and surrounding sleeve ( ). As the orifice becomes obstructed by particulate contamination, fluid flow through the device reduces. The contamination level is assessed by measuring the characteristic reduction in fluid flow rate over a period of time. Following the measurement cycle, fluid flow through the device is reversed causing the spool to move relatively within the sleeve to an area of increased bore ( ) whereby the enlarged gap allows the release of all trapped contaminants. Following this flushing cycle, the fluid is reverted to the original flow direction, the spool returns to the position within the spool that defines the narrow orifice and another measurement cycle begins.

A process for nondestructive heating and supplying of ammonia feed gas wherein high quality ammonia (typically greater than 90% and as high as 99%) is preserved at temperatures well in excess of the conventional limit of 230&deg; C. (typically from 400 to 700&deg; C.) by controlling the selection of metal surfaces in contact with the hot gas, the bulk temperature of the gas, the wall temperature, the pressure, the contact time, and the spatial surface density. Such hot gases are particularly useful for the manufacture of hydrogen cyanide.
