Design and characteristics of electric supercharger for diesel engine acceleration by additional rapid

YAO Chun-de, ZHOU Hong-xiu

Frontiers of Mechanical Engineering 2006, Volume 1, Issue 4,   Pages 409-412 doi: 10.1007/s11465-006-0048-5

Abstract: The ES (electric supercharger) driven by a high-speed brushless motor was developed to solve the problem of smoke caused by the turbocharger s sluggish response during acceleration. Its rotation speed was from 6 000 r/min to 24 000 r/min, and the maximum flux was 0.1 kg/s. The structural design of the electric supercharger is novel, which makes it easier to set the lubricating installation and to assemble. The velocity distribution at the outlet of the electric supercharger is determined by hot-wire anemometry under various rotation speeds in steady state. Furthermore, the trends of the flux and charge rate with various speeds were analyzed. In addition, the transient response was detected from the motor setup to smooth running within 10 s, 15 s, 20 s and 25 s respectively, and the characteristic of the transient flux is under pilot study. Research results indicate that the electric supercharger can respond rapidly with the great flux, and it is independent of the operating conditions of a diesel engine. Therefore, it is a feasible way to reduce smoke emission and improve the acceleration performance.

A study on rapid acid chrome black (MB 7) spectrophotometric determination of ClO

Jing DONG, Huilong WANG

Frontiers of Chemical Science and Engineering 2011, Volume 5, Issue 2,   Pages 245-251 doi: 10.1007/s11705-010-1003-x

Abstract: Experiments were conducted to investigate the degradation of 2,6-dinitro- -cresol (DNPC) in the chlorine dioxide (ClO ) catalytic oxidation process. Pure aluminum oxide was used as the catalyst in this process. The degradation of DNPC by ClO using aluminum oxide as catalyst was systematically studied by varying the experimental parameters, such as pH values, catalyst dosage, the initial concentration of DNPC and ClO , reaction time, etc. Under optimal condition (DNPC concentration 39 mg·L , ClO concentration 0.234 g·L , reaction time 15 min, catalyst dosage 4.7 g·L and pH 4.32), almost complete degradation of DNPC can be achieved. The kinetic studies revealed that the ClO catalytic oxidation degradation of DNPC followed pseudo-first-order kinetics with respect to both ClO and DNPC concentration. The repetitive use of the catalyst was investigated along sequential feed-batch trials. The catalyst performed efficiently after five runs. In addition, a simple and convenient method for the determination of ClO in water was developed by using acid chrome black 7 (MB 7) spectrophotometry in this paper.

A microextraction approach for rapid extraction and separation of Mn(II) and Co(II) using saponified

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 6,   Pages 963-972 doi: 10.1007/s11705-021-2081-7

Abstract: In this paper, we proposed a microextraction approach for the extraction and separation of Mn(II) and Co(II) from sulfate solution simulating leachate of spent lithium-ion battery cathode materials using saponified di-(2-ethylhexyl)phosphoric acid system. The effects of the following operational variables were investigated: equilibrium pH, tri-n-butyl phosphate concentration, saponification rate, two-phase ratio and residence time. The results showcased that the microextractor can reach the extraction equilibrium within 20 s, thereby greatly reducing necessary extraction time comparing to that of conventional processes. The volumetric mass transfer coefficient showed 8–21 times larger than that of batch device. With the help of microextractor, 95% of Mn(II) was extracted with a single theoretical stage at a chosen two-phase ratio of 3:1, and the separation factor βMn/Co was as large as 65.5. In the subsequent stripping step, more than 99% of manganese from loaded phase was easily stripped under optimal conditions. The microextraction approach greatly enhances the mass transfer while enabling a continuous and controllable extraction process within a simple structure design. When extracting spent electrode material with microextractors, the comprehensive recovery of mangenese can reach 96%. The microextraction approach has a good applicability in the spent lithium-ion battery cathode materials recycling at both bench and industrial scales.
