Oxidative desulfurization of real diesel was carried out at mild conditions( atmospheric pressure) in presence of phosphotungstic acid/semi-coke catalysts. The effects of two phase volume ratio, reaction temperature, on the efficiency of desulfurization were investigated. meanwhile, treatment of model solution of cyclohexane containing BT, DBT and 46-DMDBT with our ODS system at 80°C in 1h.
A kind of intelligent hydraulic impact or based on fuzzy control algorithm is put forward. The pressure peak signal from the nitrogen room is collected by the pressure sensor, through A/D conversion which is input to the computer for processing (fuzzy control algorithm) to obtain the control signal. Then, through the D/A conversion and signal amplification, respectively, the action of high-speed switch...
After analyzing the hydraulic impactor at home and abroad, a new control strategy of self-adaptive buffer has brought forward and a vibration mechanics model of buffer has established in this paper. We also designed a control system of self-adaptive buffer of hydraulic breaker which was controlled by single-chip computer. At the same time, we set up a simulink model of microcomputer control system...
