摘要:
The present invention relates to a catalyst comprising a macroporous noble metal-containing zeolite material and a porous SiO2-containing binder, wherein the catalyst has a proportion of micropores of more than 70%, based on the total pore volume of the catalyst. The invention is additionally directed to a process for preparing the catalyst and to the use of the catalyst as an oxidation catalyst.
摘要:
The invention relates to a method for the selective catalytic transformation of nitrogen-containing compounds. The transformation relates to the selective catalytic reduction (SCR) of nitrogen oxides, or the selective catalytic oxidation (SCO) of nitrogen hydrides and nitrogen-containing organic compounds, preferably in waste gas flows of combustion processes with motors and without motors and industrial applications. The catalytic converter comprises a titano-(silico)-alumo-phosphate.
摘要:
A radio-frequency power component and a radio-frequency power module, as well as to methods for producing them are encompassed. The radio-frequency power component has a semiconductor chip that is suitable for flip chip mounting. The semiconductor chip has an active upper face that produces power losses. This active upper face is covered by an electrically isolating layer leaving free contact surfaces, with a heat-dissipating metal layer being applied to its upper face. The metal layer directly dissipates the heat losses from the active semiconductor structures.
