摘要： Ammonia exchanged large port mordenite, which is subsequently mildly acid leached, and calcined, in which at least 95% of the exchangeable sodium has been removed and having from 0.38 to 0.8 milliequivalents of acid sites at least as strong as 48% sulfuric acid per gram (as measured by titration with butylamine, and employing dicinnamalacetone indicator) has been found to be a highly active hydrocarbon isomerization catalyst. Incorporation of noble metal, e.g. palladium, on the catalyst improves the selectivity for isomerization of normal pentane to isopentane for highly active catalysts at high conversion rates.

摘要： High surface area alumina bodies for use as catalysts, catalyst carriers, and sorbents are made by controlled mixing of fine particle size platy boehmite alumina aggregates with a monobasic acid to produce non-pasty free-flowing particulate mass of aggregates of boehmite. This mass can then be formed by pressure into selected shapes such as rings, saddles, cylinders, solid, or hollow, or pellets, dried and fired to produce bodies of boehmite, gamma alumina, delta alumina, theta alumina or alpha alumina ranging in surface area of from 10 square meters per gram to greater than 300 square meters per gram. Catalytic metal can be included in the bodies by impregnation, before or after firing, or can be incorporated by inclusion in the aqueous acid treating solution.

摘要： A multiwell apparatus for the assay of microliter quantities of body fluids is provided which prevents fluid loss by lateral migration or gravity flow through a microporous membrane or ultrafilter. A sample is passed through a membrane to which an antibody has been bonded in order to harvest complementary viral antigens in the sample. The harvested viral antigen is converted to single strand DNA or RNA which then is deposited on a second membrane. The deposited single strand DNA or RNA is capable of reacting with labeled DNA or other suitable detection probe which can be detected and correlated with antigen concentration in the sample.
