TL;DR: In this article, a phosphorus and aluminum containing sol for petroleum hydrocarbon cracking catalyst and its features are containing Al 2-10 wt, P 5-20 wt% and no Cl, with its P/Al ratio being 12-6 and pH value being 10-25.
Abstract: The present invention relates to a phosphorus and aluminum containing sol for petroleum hydrocarbon cracking catalyst and its features are containing Al 2-10 wt%, P 5-20 wt% and no Cl, with its P/Al ratio being 12-6 and pH value being 10-25 The preparation process includes beating aluminium hydroxide or alumina capable of being peptized and deionized water to obtain a slurry with solid content of 15-35 wt%, adding concentrated phosphoric acid according to the required P/Al ratio while stirring, heating to 65-95 deg and reaction for 15-90 min until becoming transparent colloid The said phosphorus and aluminum containing sol without C1 may be used together with conventional chlorine-containing aluminum sol

TL;DR: The fractional uptake of ingested aluminium and aluminium compounds from the gastro-intestinal tract of adult female rats was measured and results produced for aluminium citrate, aluminium hydroxide and aluminium sulphate are close to those published for man.
Abstract: The fractional uptake of ingested aluminium and aluminium compounds (aluminium citrate, aluminium nitrate, aluminium chloride, aluminium sulphate, aluminium hydroxide, aluminium oxide, aluminium metal, powdered aluminium pot electrolyte, acidic sodium aluminium phosphate (SALP), basic sodium aluminium phosphate (Kasal), sodium aluminium silicate and FDC 002% for aluminium oxide; 004% for powdered pot electrolyte; 012% for sodium aluminium silicate; and 009% for FD&C red 40 aluminium lake For aluminium metal, SALP and Kasal the amount of 26Al present in the rats was insufficient to determine uptake and was less than 003% The results produced for aluminium citrate, aluminium hydroxide and aluminium sulphate are close to those published for man

TL;DR: In this article, a method for preparing non-shaped aluminum hydroxide with high acid dissolubility and low density has been proposed, which employs continous feeding and carbon dioxide of high concentration for glue forming to fasten neutralizing reaction and shorten glue forming time.
Abstract: The invention discloses a method for preparing non-shaped aluminum hydroxide, relating to an aluminum hydroxide, especially relating to a method for preparing aluminum hydroxide with high acid dissolubility and low density The method comprises following steps: preparing strong sodium metaaluminate with gibbsite and sodium-hydroxide to control solution caustic ratio; diluting with deioned water and adding hole enlarging agent; adding deioned water into autoclave firstly, got solution of raw material and carbon dioxide flows into autoclave to control glue forming temperature; regulating feeding flow rate and filtering, washing and drying slurry and getting said product The invention employs continous feeding and carbon dioxide of high concentration for glue forming to fasten neutralizing reaction and shorten glue forming time, and thus prevents diaspore generation, saves cooling device, increases device usage or reduces autoclave volumn The product can dissolve into hydrogene nitrate of 20% completely and the bulk density is less than or equal to 04 g/ml

TL;DR: In this article, the carbon aluminate is dissolved out the material by weak sodium carbonate solution to be made into carbon-aluminate solution that density is less than 100 g/f.
Abstract: The invention provides a new technology for extracting aluminium oxide from the material containing carbon aluminate. The carbon aluminate is dissolved out the material by weak sodium carbonate solution to be made into carbon aluminate solution that density is less than 100 g/f, gas CO2 is send into the carbon aluminate solution to do decomposition to generate high-silicon aluminium hydroxide and carbon decomposition mother solution which circulately dissolving out carbon aluminate, the high-silicon aluminium hydroxide is processed by low-temp. dissolving, seed-decomposed decomposing and burning to produce quality sand-type aluminium oxide.
