Preparation of Organic/Inorganic Composite Phenolic Resin and Application in Al2O3‐C Refractories

An organic/inorganic composite phenolic resin (CPR) was synthesized via silicon particles in situ composite with water‐soluble lignin–phenolic resin. It was observed that silicon particles were uniformly dispersed in the organic matrix. The oxidation activation energies of the pyrolytic products from CPR and commercial phenol formaldehyde resin (PF) were calculated as 173.3 kJ/mol and 102.4 kJ/mol, respectively, by nonisothermal kinetics method. Dumbbell‐shaped silicon carbide nanowires were formed on the surface of the pyrolytic carbon from CPR at high temperature. The oxidation resistance and mechanical properties of the Al₂O₃‐C refractories bonded with CPR were improved.

煤矸石盐酸浸溶出铝铁的动力学研究（英文）

The extraction of aluminum from coal mining waste (CMW) is an important industrial process. The two major problems in applications are low aluminum dissolution efficiency and high iron content in the raw material, which affect the quantity and quality of products. To improve the aluminum recovery process, the leaching kinet-ics of CMW with hydrochloric acid was studied. A shrinking core model was used to investigate aluminum and iron dissolution kinetics. Based on the kinetic characteristics, a process for recovering aluminum was proposed and tested experimental y. It is found that the aluminum leaching reaction is controlled by surface reaction at low temperatures (40–80 °C) and by diffusion process at higher temperatures (90–106 °C). The iron dissolution process is dominated by surface reaction at 40–100 °C. The results show that iron could be dissolved or separated by concentrated hydrochloric acid. Fine grinding wil improve aluminum dissolution significantly.
