摘要： Coking of residual oil and devolatization/partial gasification and desulfurization of solid particulate fuel are carried out in a single reactor. The particulate fuel is burned in a combustion zone in the bottom of the reactor. A bed of particulate fuel is fluidized above the combustion zone with gases rising from the combustion zone. The fluidized bed is maintained at a temperature which cokes the residual oil and volatizes the particulate fuel. A high temperature, low velocity zone is maintained between the combustion zone and the fluidized bed for calcination and desulfurization of the solid fuel.

摘要： A process for demetallation and desulfurization of resids by visbreaking an admixture of resids, particulate solids, and steam and/or hydrogen, and then subjecting the visbroken mixture to high temperature settling and separating to provide a first vapor product, a liquid product, and a recycled underflow solids stream. The process further comprises coking the liquid product to produce a second vapor product and coke and then distilling the combined first and second vapor products to yield a plurality of demetallized and desulfurized liquid hydrocarbon products. A fraction of the recycled underflow from the settler/separator is removed as a purge stream and burned for recovery of heat and metals. If hydrogen is used in the visbreaking step, the first vapor product is condensed to separate the hydrogen for recycling.

摘要： In the combustion of high sulfur coal, SO.sub.x emission is reduced by pyrolizing the coal in a reducing atmosphere to form char and convert the sulfur compounds to combustible gases including H.sub.2 S. The H.sub.2 S is reacted with the coal and the char to produce ash containing sulfur which is easily removed from the combustion process. A three zone furnace includes a zone in which the coal is pyrolized in a reducing atmosphere to convert the sulfur compounds to combustible gas which reacts with the coal and char.

摘要： The present invention relates to a process for effectively recovering uranium from dilute solutions, particularly alkaline carbonate leachates from an in-situ leaching process. The uranium complexes are made unstable by adjusting the pH of the leachate to about 6.5 using mineral acids or carbon dioxide. The solution is then passed over ion exchanger resin which induces percipitation of uranium. This non-exchangeable uranium on the resin is then eluted or leached with acid or carbonate solution to obtain eluate of high uranium concentration.

摘要： The rejuvenative catalytic oxidation of offensive substances, such as cyanides, sulfides, sulfites, thiosulfates, mercaptans, disulfides, ammonia and mixtures thereof, contained in waste water. The process involves the addition of a low concentration of a metal compound to the waste water to be treated and then passing the waste water along with a source of oxygen over an adsorbent material, thus catalytically oxidizing the offensive substances contained in the waste water. The process reduces the catalytic impact of the loss of metal from the adsorbent material due to leaching and allows the catalyst to be rejuvenated and allows recovery from process upsets in the treating system without unit shutdown and catalyst replacement. An example of the catalytic support is activated carbon and an example of the metal is copper.
