The phrase "activate catalyst" is correct and usable in written English.
It can be used in contexts related to chemistry, processes, or systems where a catalyst is involved in initiating or accelerating a reaction or change.
Example: "To begin the reaction, you need to activate the catalyst by heating it to the required temperature."
Alternatives: "initiate catalyst" or "trigger catalyst".
At 210 °C, the newly activated catalyst lost about 1 2 wt% of its activity and then reached a pseudo-stable state for the initial 60 min on stream.
Unlike the CO activated catalyst, the syngas activated iron catalyst resulted in a lower amount of χ-Fe5C2 than ɛ-Fe2.2C.
The attrition resistances of the differently activated catalyst samples were found to be similar to that of the calcined catalyst for this spray-dried Fe catalyst.
Although, XRD indicated that different Fe phase compositions resulted in the differently activated catalyst samples, chemical attrition was not observed for any of the samples.
PP produced with the catalyst activated by a 50/50 TEA/TiBA mixture has the same content of highly isotactic chains as PP produced with the TEA activated catalyst, but main TREF fractions of the former has higher microisotacticity than the later.
The initial conversion at 230 °C for the newly activated catalyst remained unchanged for about 2 days on stream, and then slightly decreased over time, with an overall conversion of 77 wt% after 30 min decreasing with the TOS to 74 wt% after 2,700 min, and then decreased slowly within the deactivation rate range of 1 to 2 wt% every 24 h until the reaction was finally terminated after about 86 h.
Figure 10 TGA/DTA of spent and activated catalysts.
Activated catalysts follow the sequence: reoxidation > reduction > calcination, when glycerol conversion is compared.
After eliminating the majority of convergence, we found the convergence pattern among activating catalysts, printing, advanced networking, controlling devices, secured communication with in-memory system, television system with pattern recognition, and image processing and analyzing technologies.
The process uses an electron-beam (e-beam) in the presence of water vapor to activate a catalyst support at select locations, on which CNT forests can grow selectively when exposed to the CNT catalyst and precursor.
