"particle" nach Englisch mit Beispielen - Kollokationen-Wörterbuch Englisch
- A third component of most catalysts is a carrier, a material that determines the size and the shape of catalyst particles.
- The bottom product oil from the main fractionator contains residual catalyst particles which were not completely removed by the cyclones in the top of the reactor.
- The catalyst particle remains buried in the growth tip of the fiber at a final concentration of about a few parts per million.
- The formation of carbides appears to improve catalytic activity, however it can also lead to the mechanical break-up and attrition of the catalyst particles.
- Carbon-rich "coke" deposits on the catalyst particles and deactivates the catalyst in less than 1 second.
- Even the size of the catalyst particle can change the way a reaction runs.
- Control of these phase transformations can be important in maintaining catalytic activity and preventing breakdown of the catalyst particles.
- Many of those preparations suffer from deposition scarce, unwanted large size or aggregates of catalyst particles even at a relatively low loading content.
- These reactors are tubular and are filled with solid catalyst particles, most often used to catalyze gas reactions.
- Subsequently it will polymerise, initiated by catalyst particles (Grubbs catalyst) that are also dispersed through the system.
