The membrane reactor displayed a maximum p-xylene yield of 5.1% at 523 K when computed at permeate-only mode, decreasing with temperature.
The injector setting was a pulsed spit less mode with a temperature of 250°C at a standard pressure.
Helium was used as mobile phase and 1 µL of sample was injected for analysis in splitless mode, with injector temperature set at 140 °C.
The short stack was tested in the constant resistance load regime, in dead-end mode, with controlling temperature by air on-off control system.
This paper presents a numerical investigation on three typical types of VM-PT cryocoolers, which are gas-coupling mode with room temperature phase shifter (GCRP), gas-coupling mode with cold phase shifter (GCCP) and thermal-coupling mode with cold phase shifter (TCCP).
Moreover, a significant blueshift of the two modes with increasing annealing temperature was noticed which may be explained by a phase separation between Si-np and the Si nitride medium.
The discharge study performed in this geometry showed that three modes of discharge development were realized under the experimental conditions: a spark mode with high-temperature channel formation, a streamer mode with nonuniform gas excitation, and a transient mode.
AVGL values were calculated from the acquired B-mode images and correlated with temperature variations.
The sensor operates in both constant current and constant temperature modes, with a feedback on current enabled by uncoupling heating and measurement.
