Abstract: A method of forming a carrier material suited to use in Fischer-Tropsch reactions includes forming a dispersion of first and second hydrated alumina materials in a liquid dispersant, such as an acid solution. The first alumina can be derived from an alkali aluminate, such as is formed in the Bayer reaction. The second hydrated alumina can be derived from high purity aluminum, such as via conversion to an alkoxide. The dispersion is spray dried to form particles which are heat treated to form a carrier material having low levels of impurities.

Abstract: The selectivity and activity of a silver-based olefin epoxidation catalyst i s found to be a function of the pore size distribution in the alumina carrier on which it is deposited. Specifically it is found advantageous to provide a carrier which has a minimum of very large pores, ( greater than 10 micrometers) and a water absorption of 35 to 55% and a surface area of at least 1.0 m2 /g. A method of making such carriers is also described.

Abstract: The invention provides media for absorption of phosphate and metal contaminants from a hydrocarbon stream and a method of making such media. The media comprise alumina with relatively minor amounts of calcia and magnesia and are made by a process in which the minor components or precursors of such components are dispersed in a gelled sol of a hydrated alumina such as boehmite.

Abstract: Ceramic mass and thermal transfer media suitable for use in thermal regenerative oxidizers made using a mixture of a ball clay, talc and optionally a dolomitic limestone have enhanced resistance to environments containing halogens and hydrogen halides. The media preferably comprises less than 0.25% by weight of alkali metal, expressed as the oxide, and has a cordierite: silica phase ratio of less than 1.2:1, as determined by X-ray diffraction.

Abstract: A carrier comprises non-platelet alumina. The carrier has a surface area of at least 1 m 2 /g, a total pore volume and a pore size distribution wherein at least 80 % of the total pore volume is contained in pores with diameters in the range of from 0.1 to 10 µm, and at least 80 % of the pore volume contained in the pores with diameters in the range of from 0.1 to 10 µm is contained in pores with diameters in the range of from 0.3 to 10 µm.

Abstract: A process for manufacturing a porous ceramic body- using a pore former containing potassium is disclosed. The pore former is treated to reduce the concentration of the potassium prior to forming a mixture with a heat sinterable material, such as alumina. Porous ceramic material, particularly carriers for catalyst used in epoxidation reactions, can be manufactured using the process disclosed herein.
