Ground Stress Analysis and Automation of Workface in Continuous Mining Continuous Backfill Operation
The cost, complexity, lack of filling space and time create challenges in the longwall backfill operation, resulting poor subsidence control reduced productivity. This paper proposes an automated continuous mining (CMCB) method by examining its key requirements investigates optimum sequence coal panel (such as drifts) excavation to ensure ground strata at relatively high CMCB adopts highwall te...
Selective electrocatalysts are urgently needed for carbon dioxide (CO2) reduction to replace fossil fuels with renewable fuels, thereby closing the carbon cycle. To date, noble metals have achieved the best performance in energy yield and faradaic efficiency and have recently reached impressive electrical-to-chemical power conversion efficiencies. However, the scarcity of precious metals makes ...
A naphtha catalytic reforming unit with four reactors in series is analyzed. A physical model is proposed to describe the catalytic reforming radial flow reactor. Kinetics and thermodynamics equations are selected to describe the naphtha catalytic reforming reactions characteristics based on idealizing the complex naphtha mixture by representing the paraffin, naphthene, and aromatic groups by s...
