Discharge atmospheric pressure

In atmospheric pressure discharges, where concentrations of N atoms are greatly reduced and possibly absent, the discrimination between alkanes and alkenes is not observed and an alternative means of initiating the reaction is required. In the absence of significant concentrations of N, the mechanism may consist of collisional energy transfer from N2(A32 +), which lies 593 kJ mor1... [Pg.364]

Although some early research did focus on introducing a pulsed external ion beam from a plasma jet into the acceleration region of the TOF-MS [12], it has not been until recently that continuous ion sources such as plasmas, electrospray devices, and other atmospheric-pressure discharges have been coupled with TOF-MS. Unfortunately, the inherently pulsed nature of the spectrometer can cause this marriage to be quite inefficient. The primary challenge in using the TOF-MS with... [Pg.453]

The reverse process is obvionsly exothermic. Dilnted ozone mixtures are relatively stable at low temperatures. However, even a relatively small heating leads to ozone decomposition, which can be explosive if the O3 concentration is sufficiently high. Thus, effective O3 synthesis should be performed at low temperatures, typically at room temperature. Carrying out the highly endothermic process (6-63) at room temperatnre requires the application of strongly non-equilibrium methods of chemical synthesis. Non-eqnilibrinm plasma of a dielectric barrier, pulsed corona, and other non-thermal atmospheric-pressure discharges are some of the most efficient methods for practical ozone production. [Pg.382]

Contribution of the Electron Flux from Non-Thermal Plasma into Deactivation of Bioiogicai Micro-Organisms. Based on the equation (12-1) describing contribution of the non-thermal plasma electrons into sterilization, derive corresponding formula for the survival curve. Compare the curve related to contribution of plasma electrons with experimental survival curves for atmospheric-pressure discharges presented in Section 12.2. [Pg.912]

Once interstage pressures have been estimated, the steam requirements for each stage can be also estimated from Figure 23-17. If the estimates indicate steam flows less than 50 Ib/hr, the design air load should be adjusted so that 50 Ib/hr of steam is required as the minimum to any stage. Normally, the atmospheric pressure discharge stage will have a suction pressure of about 150-200 torr and will require the least amount of steam. [Pg.246]
