摘要: The accumulation of gaseous ammonia in areas wherein animals are housed or maintained is controlled by providing to the areas animal litter, bedding, or other absorbent material which contain a low molecular weight, non-volatile organic acid. Acids such as citric, malic, fumaric, phosphoric, tartaric, maleic, malonic, succinic, sorbic and mixtures of these acids are used and especially phosphoric and fumaric. These acids can be used in concentrations of about 0.0001 to 2 wt % of the dry bedding.

摘要: Porous bodies are produced which are suitable for use as supports for catalysts, including living cells, such as bacteria. The bodies have a significantly large average pore diameter of about 0.5 to 100 microns, (i.e. 5,000 to 1,000,000 .ANG.) and a total pore volume of about 0.1 to 1.5 cc/g with the large pores contributing a pore volume of from about 0.1 to 1.0 cc/g. The bodies are made by preparing a mixture of ultimate particles of bound clay, one or more optional ingredients such as inorganic binders, extrusion or forming aids, burnout agents, or a forming liquid, such as water. In a preferred embodiment, the ultimate particles are formed by spray drying.

摘要: Porous titania or zirconia spheres having a particle diameter of about 1 to 100 microns, a pore volume of about 0.1 to 1 cc/g, and a pore diameter in the range of about 10 to 5,000 Angstrom units are made by spray drying a slurry of ultimate titania or zirconia particles having a diameter about equal to that of the desired pore diameter of the formed sphere, and a reactive binder. The spheres can be used in high performance liquid chromatography columns and as catalyst supports.

摘要: Porous bodies are produced which are suitable for use as supports for catalysts, including living cells, such as bacteria and which are upset resistant to acids and bases. The bodies have a significantly large average pore diameter of about 0.5 to 100 microns, (i.e. 5,000 to 1,000,000 .ANG.) and a total pore volume of about 0.1 to 1.5 cc/g with the large pores contributing a pore volume of from about 0.1 to 1.0 cc/g. The bodies are made by preparing a mixture of ultimate particles containing a zeolite and one or more optional ingredients such as inorganic binders, extrusion or forming aids, burnout agents, or a forming liquid, such as water. In a preferred embodiment, the ultimate particles are formed by spray drying.
