Abstract: A blending/loading system wherein an elongated cylinder or fuel rod is positioned on a turntable underneath a series of hoppers containing the particulates to be blended/loaded. Separate transfer tubes from each hopper are aligned with the cylinder and are subsequently lowered into the cylinder. Upon lowering, the cylinder is rotated and nozzles at the ends of the transfer tubes are activated to discharge, disperse and mix the stored particulates into the rotating cylinder. As the cylinder fills up, the transfer tubes are withdrawn from the rotating cylinder until the desired amount of fill is reached. Afterwards, the nozzles block any additional flow from occurring as they are raised out of the cylinder.

Abstract: Catalysts are disclosed which have good activity and life when used to promote the conversion of hydrocarbons, carbon monoxide and nitrogen oxides contained in small concentrations in gaseous streams, to obtain the less noxious materials, carbon dioxide, water and nitrogen. The catalysts contain a catalytically promoting, platinum group metal component, a catalytically promoting, base metal component and an alumina support component, deposited on a high surface area, particulate, macrosize carrier. The base metal component contains a metal selected from the group consisting of metals having an atomic number from 25 to 28 and rhenium.
