摘要： A process for preparing iron oxide with a controlled purity and large particle size which comprises oxidizing at a constant pH a vigorously agitated aqueous suspension of iron oxide crystals while continuously, but slowly adding a water soluble iron solution and continuously withdrawing a portion of the aqueous solution containing large size iron oxide crystals as product.

摘要： Bitumen recovery from a tar sands emulsion or other bituminous oil-in-water emulsion is increased by milling the emulsion for a time sufficient to cause a bitumen-rich liquid fraction to rise to the surface, and separating such fraction. Addition of water to the starting emulsion or during milling further enhances the recovery of bitumen.

摘要： An improvement in the treatment of sludge recovered from a pond containing tailings from a water extraction process of tar sands characterized in that the froth produced from a treatment of the sludge is diluted with water which is at an ambient temperature, and the diluted froth is agitated and aerated vigorously for a short time to obtain an upper froth layer which contains most of the bitumen and substantially reduced amounts of mineral and water. The upper froth layer is obtained by, e.g., skimming it from the froth produced by the agitation and aeration.

摘要： Whole crude shale oil is contacted with a suitable catalyst, e.g., cobalt molybdate on alumina, and hydrogen within a temperature range of about 600.degree. F.-850.degree. F. and a pressure range of about 200 psig-5000 psig until a substantial amount of nitrogen compounds contained in the oil are converted to at least basic nitrogen compounds. Hydrogen consumption is high, about 700-3000 SCF/Bbl of fresh oil charged. The contacted oil, containing basic nitrogen compounds in the oil, formed by the hydrogen contacting, is reacted with dry HCl and resulting reaction product is removed from the oil. The reaction product can be converted into hydrogen and HCl for use in the process. As a result of the severe hydrogen contacting and the HCl treatment, a major amount of the whole crude shale oil can be converted to jet fuel.
