    摘要: An improved process is provided for decarbonizing, demetallizing and/or desalting a hydrocarbon feed stock by: contacting, in a selective vaporization step, for a short hydrocarbon residence time at an elevated contact temperature, the feed stock with an inert solid contact material in a confined rising vertical column to vaporize a major portion of the feed stock and to provide, as combustible deposits on the contact material, an unvaporized minor portion of the feed stock which includes high Conradson Carbon components and/or metal-containing components of the feed stock; separating the vaporized major portion of the feed stock from the contact material bearing the combustible deposits; contacting in a combustion step the contact material, bearing the combustible deposits, with an oxidizing gas to oxidize the combustible deposits and generate heat, whereby the contact material is heated by combustion of the combustible deposits; and recycling the so-heated contact material to contact further feed stock in the selective vaporization step. The improvement in the process comprises:contacting the contact material in the combustion step with less than the stoichiometric amount of oxidizing gas, required to oxidize completely the combustible deposits, so that oxidizable high Conradson Carbon and/or metal-containing components of the combustible deposits are only partially oxidized to carbon monoxide and so that there is a reducing atmosphere in the combustion step.

    摘要: A novel sorptive clay product is formed by treating attapulgite clay with sodium silicate and heating to expel moisture such that the product contains about 7-20% total volatile matter. Acid may also be added such that the pH of aqueous slurry is in the range 5 to 10. This sorptive clay product exhibits water and oil absorption and resistance to wet breakdown equivalent to higher-temperature activated attapulgite products.

    摘要: Process and system are described for control of sulfur oxide in emissions to the atmosphere from regenerators of Fluid Catalytic Cracking Units (FCC) in a manner which improves the operation of the regenerator and/or the reactor. Spent FCC cracking catalyst containing sulfur-bearing inactivating carbonaceous deposit is partially oxidized, preferably in the presence of steam, thereby producing a mixture of CO and CO.sub.2 and releasing sulfur in the resulting reducing atmosphere as vaporous hydrogen sulfide before the catalyst is regenerated, whereby the amount of sulfur convertible to noxious SOx in the regenerator flue gas is reduced. By the disclosed process and system, the quantity of oxygen introduced is predetermined and controlled in response to hydrogen content of the coke on the partially oxidized catalyst or an SOx analyzer associated with the regenerator can be used as a control tool. Preferably, spent catalyst is partially oxidized in the presence of steam in a vessel separate from the regenerator and reactor, whereby the effluent can be utilized as a source of low BTU gas.

One or both of those fractions is mixed with a catalytically inert solid at high temperature to transfer metallic compounds and Conradson Carbon components to the solid for improvement of the fraction.

    摘要: An improved process for the production of mechanically strong shaped crystalline zeolitic aluminosilicate bodies from precursor bodies composed of kaolin clay calcined at elevated temperature, the crystallized bodies having essentially the same size and shape as the precursor bodies. Conversion of the calcined clay contained in the precursor bodies to a mixture of crystalline zeolitic alluminosilicate component and a porous amorphous silica-alumina component takes place as a result of reaction between the calcined clay and an aqueous alkaline liquid in which the bodies are immersed. The improved process features the presence of a solution of aluminosilicate nucleation centers during such reaction.

    摘要: Tin values in the form of cassiterite (SnO.sub.2) are recovered from aqueous pulps of finely divided cassiterite-bearing ore, preconcentrate or concentrate by froth flotation. The ore pulps are deslimed thoroughly, partially or not at all. Slimes, gangue or waste minerals in the pulps are selectively depressed by use of a metal salt/silicate reagent combination. The cassiterite is floated at a mildly acidic to neutral pH, generally in the range of about 5 to 6, by one and/or more highly selective tin collectors such as sulfosuccinamates, aspartates, phosphonates, etc., at environmental or, preferably, elevated pulp temperature. Flotation machine impeller speeds are within conventional range or higher, preferably the latter. The cleaning of the thus-produced cassiterite rougher flotation concentrate is performed after an additional (secondary) conditioning step whereby an additional depressant, such as tannic acid, sulfuric acid, sodium fluosilicate, sodium lignin sulfonate or activated charcoal is used.
