    摘要： The present invention provides a method for purifying alkanolamine solutions which have lost at least a portion of their acid gas sorption capacity due to degradation of the alkanolamine into heat stable salts. Particularly, it has been found that the alkanolamine solution may be rejuvenated by charging the solution to the feed zone of a distillation column reactor at temperatures above about 160.degree. C. and pressure of less than about 2000 mm Hg.

    摘要： The severity of visbreaking of an oil is increased without increasing the instability of the product by incorporating into the feedstock a catalyst preferably supported on a porous substrate. The catalyst is the elemental form or compound of an element selected from the group consisting of selenium, tellurium and sulfur.

    摘要： A catalytic cracking process operates with a getter additive present where hot catalyst meets heavy metals laden crude. The getter additive is a material which is selective for metals, and has a particle size/density such that the getter additive remains in the FCC unit for no more than 24 hours, and preferably is removed within one hour or less. Addition of 1-5 weight percent alumina having an average particle size of 10-40 microns will remove much of the metal content from the feed, and the metals laden additive will itself be rapidly removed from the FCC unit preventing migration of metal or degradation of the cracking operation due to the presence of metal. Preferably the additive is fine particles which are mixed with the hydrocarbon feed to the unit.

    摘要： A method is provided for removing mercury from hydrocarbon fluids by high temperature reactive adsorption. A hydrocarbon feed passed through an adsorbent mass including a reactive adsorbent such as silver or copper sulfide on an alumina support. The optimum temperature of the feed to be treated depends upon the 90% boiling points corresponding to heavier feeds. A hydrocarbon condensate feed may be drawn from a stabilizer column in a natural gas processing plant at a temperature in excess of 400.degree. F. If a metallic silver/alumina adsorbent is employed, the adsorbent may be regenerated through high temperature oxidation. Once oxidation is complete, the temperature is lowered in a reducing or inert atmosphere.

    摘要： A regenerable molecular sieve comprises 0.001-15% elemental silver or gold in or on zeolite A. The molecular sieve is capable of simultaneously removing mercury and water from a fluid. A method for impregenating zeolite A with elemental silver or gold comprising treating the zeolite A with a solution of a silver or gold salt of a carboxylic acid and heating the impregnated zeolite A at a temperature sufficient to decompose the salt is also provided. A method for simultaneously and repeatedly removing mercury and water from a hydrocarbon fluid by contacting the fluid with an effective amount of a molecular sieve comprising zeolite A and 0.001-15% elemental silver or gold and regenerating the zeolite A at elevated temperatures is also provided.

    摘要： Combustible carbonaceous particles such as particles of sponge coke or coal are incorporated with the circulating inventory of cracking catalyst in a fluid catalytic cracking unit. The carbonaceous particles selectively sorb metal contaminants in the feed, thereby extending catalyst life, and they also serve to reduce NO.sub.x emissions in certain instances. The sorbed metals values may be recovered as the carbonaceous particles are burned.
