The molten steel in the converter is mixed with the slag by introducing a gas that is blown over the liquid phases (called top blowing), under the liquid phases (bottom blowing) or using top and bottom blowing at the same time (combined blowing).
2 With this motivation, we recently developed a new in-situ solid-state NMR technique 3 which exploits the ability of NMR to selectively observe the solid phase in heterogeneous solid/liquid systems, of the type that exist during crystallization from solution, under conditions in which the liquid phase is "invisible" to the measurement.
As seen in Fig. 9, the more content of PZ, the greater H2S loading in the liquid phase under the condition of a constant H2S partial pressure.
It has been shown that the Shah criterion fails under conditions where depletion of the liquid phase reactant occurs.
In which process, a mixture of benzene and cyclohexane was fed into the reactor at the bottom under the liquid condition, however, the liquid phase disappeared and turned into gas phase at the reactor outlet through vaporization.
The study was designed to investigate the effect of all three parameters on the degradation rate as well as their importance on unveiling the existence of mass transfer limitations in the liquid phase under specific conditions.
The first example of a redox molecular sieve was titanium silicalite-1(TS-1) developed by Enichem workers (Taramasso et al. 1983; Clerici 1991; Clerici et al. 1991; Romano et al. 1990) which proved to be active catalyst for selective oxidations with 30%% aqueous H2O2 in the liquid phase under mild conditions.
In order to increase the residence time of gas bubble in the liquid phase under the condition of a certain liquid level height, the spoiler elements (twist tape, helical fin and static mixer) used for heat transfer enhancement in pipe are introduced to the bubbling reactor based on numerical simulation method.
To determine the lowest critical rotating speed, the gas-induction mechanism was reconsidered by constituting a mechanical energy conservation equation between the gas inlet orifice in the gas phase and the gas outlet orifice in the liquid phase under a certain rotational speed.
The magnetic catalyst, with good superparamagnetism, can be easily recovered from the liquid phase system under the external magnetic field.
