Rotating disc contactor (RDC) is one of the most important extraction columns for liquid-liquid extraction. A single-stage horizontal axis RDC (HRDC) was developed and used for extraction of emulsion system. The extractor composed characteristics of narrow mixing space of 1 mm and oil-wet slits. For ethanol/water/2-ethyl-hexanol system, both mass transfer and phase separation were enhanced simultaneously

To develop a new process for reducing SO2 to elemental sulfur, the reduction of SO2 with carbon materials heated by electrical and microwave were investigated on a fixed bed experimental system. The effects of carbon species, temperature, SO2 concentration and C/SO2 molar ratio on SO2 reduction were studied. The results showed that coconut shell activated carbon has the best reduction effect among

This work proposes the optimization of 2-ethylhexyl (2-EH) caprylate/caprate synthesis in a pulsed loop reactor, and the energy efficiency of the reactor was assessed. 2-EH caprylate/caprate can be used as a biodegradable base fluid. Only 0.4 wt% catalyst concentration was used in the reaction. The face-centred central composite design (FCCD) experiment coupled response surface methodology (RSM) has

Photocatalysis and ozonation have limited efficiency for the degradation of persistent pollutants as well as the mineralization of byproducts. In this work, we intensify the degradation processes by using simultaneously both processes in macroporous catalytic supports under mild reaction conditions, for degradation of tetracycline. The total organic carbon removal reached up to 90% after 180 min of
