Nanostructured zincoxide (ZnO) was synthesized via a sonochemical method. The effect of the duration of ultrasonic irradiation in a continuous mode on the generated particles was investigated. Additionally, the effect of flowing either air or nitrogen during the sonication process was investigated. Zinc nitrate and
ammonia water-based solutions were selected as chemicals without the addition
of other surfactants. The generated particles indicated that a wurtzite
structure of ZnO in a hexagonal phase was formed with a crystalline size ...

Coupling power generation with syngas-based chemical synthesis according to the so-called ‘Polygeneration-Annex’ concept offers economic and technical benefits. Clemens Forman assesses the integration of incoming streams by the Annex plant from a power plant point of view across its full load range. Analyses are done by load-dependent flowsheet simulation. The pulverized lignite combustion power plant process is covered by two generic technical states: an existing 650 MW(el) power plant and a near future 1,100 MW(el) ...
