Fe 2 O 3 /γ–Al 2 O 3 catalyst is prepared by incipient wetness impregnation. The catalyst is characterized by temperature programmed reduction (TPR), X-ray diffraction (XRD), scanning electron microscope (SEM) and thermogravimetric analysis (TGA). The catalytic activity of Fe 2 O 3 /γ–Al 2 O 3 catalysts is evaluated via the experimental...
A motion simulator of deep-sea mining ship is designed for the 6000m deep-sea poly-metallic mining system, the control methods and the performance of the simulator are researched and tested. PID control is chosen. To determine PID control parameters, mathematical model of valve controlled cylinder system is established and validated by simulation tests. Based on the mathematical model, PID control...
Elephant grass is a fast growing and low nutrient demand plant with significant potential as a renewable energy source. In this work, the influence of heating temperatures, N2 sweeping gas flow rates and CaCl2 catalyzer weights on the yields of products and chemical composition of bio-gas was investigated by pyrolysis and catalytic pyrolysis of elephant grass in a fixed bed reactor. The results showed...
