Hydrogen quartz-glass reactor

Catalytic Hydrogen Combustion 2 [CHC 2] Quartz-glass Micro Reactor for Catalytic Hydrogen Combustion... 

Platinum dispersion was measured by hydrogen chemisorption. A dynamic pulse technique was used similar to that reported by Heck et al. Brie%, lOOmg of catalyst was introduced into a quartz glass vertical reactor and kept in porition by 2 plugs of quartz wool A pulse of... 

The gas phase hydrogenation of crotonaldehyde (2-butene-l-al from Aldrich, purity > 99.5%, used without further purification) was carried out in a quartz glass tubular reactor under atmospheric pressure. Typically, 1-10 mg of the chloride precursor were loaded into the reactor. In order to obtain a suitable catalyst bed...
