摘要： A method of preparing an alumina-based bodies suitable for use as an adsorbent or catalyst, the method comprising providing a source of activated alumina powder for forming into bodies and providing an aqueous solution containing at least two different alkali metals, at least one alkali metal derived from a soluble carboxylic acid alkali metal salt. As said powder is formed into said bodies, the bodies are contacted or sprayed with the aqueous solution to provide composite bodies containing the alumina powder and the alkali metals and the soluble carboxylic acid alkali metal salt. Alternatively, the alumina bodies may be formed first and then contacted, e.g., soaked in the aqueous solution. Or, a viscous slurry of the activated alumina powder and the aqueous solution may be made. The viscous slurry may be made into bodies by extrusion or by the oil drop method. Thereafter, the bodies are thermally treated to activate alumina therein and remove or decompose the organic part, e.g., carboxylic acid, of the soluble carboxylic acid alkali metal salt.

摘要： This invention relates to an improvement in prilling whereby water is atomized into a prill tower to affect faster solidification of the prill, and in particular, the outside surface of the prill by providing an increased rate of surface cooling while reducing the required air flows in the tower. This results in a major reduction in air pollution potential in the form of both fume and particulate while at the same time allowing substantial production rate increases. Specifically, the invention relates to quick freezing the outside surface of the prill by flash evaporation of finely atomized water particles on the surface of the prill or in extremely close proximity to the prill to greatly lower the vapor pressure at the prill's surface and by continued flash evaporation to enhance cooling so as to allow upward flowing air to be reduced to a point where micro-prills which are formed in prilling can settle in the prill tower while obtaining the same or increased production rates. More specifically, the present invention relates to an improvement in melt prilling of water sensitive materials, in particular, ammonium nitrate, urea, potassium nitrate and other water soluble melts which normally absorb water or go into solution readily at ambient conditions in their solid state.

摘要： A process is disclosed for the liquid phase separation and recovery of hydrogen fluoride from a mixture comprising hydrogen fluoride and a fluorinated organic hydrocarbon. The process requires that the mixture be treated with a sufficient amount of a coupled phase-separating agent comprising an organic or inorganic salt, an alkanolamine or mixtures thereof and a substituted or unsubstituted aromatic compound to form a first and a second phase. The first phase that is formed is a hydrogen fluoride-rich phase that additionally contains substantially all of said salt, said alkanolamine or mixtures thereof from the coupled phase-separating agent. The second phase comprises substantially all of said aromatic compound and the fluorinated organic hydrocarbon. It is substantially free of hydrogen fluoride. The phases are separated from each other. Hydrogen fluoride and the salt, alkanolamine or mixtures thereof are then recovered from the separated first phase and the aromatic compound and fluorinated organic hydrocarbon are recovered from the separated second phase.
