High Speed and Continuous Carbonization of Agricultural Forestry Products Wastes (I)

Conversion of Municipal Solid Wastes into Biochar through Hydrothermal Carbonization

In this study, the hydrothermal treatment of municipal solid wastes (MSWs) for the production of biochar as a renewable solid fuel was investigated. The properties of surrogate MSWs and mixtures of newspaper and vegetables were greatly improved by hydrothermal treatment and were similar to those of coal-like fuel substances. Hydrothermal treatment increased the calorific value, the fixed carbon...

The Influence of Hematite on High Speed Continuous Casting of Steel Lubricating Powders: Viscosity and Crystallization

Mold powders used in the continuous casting of steel contain the harmful CaF2 as a main substance developing toxic gases such as SiF4 and HF at elevated temperatures. In this study, three samples of I1, I2 and I3, which contained gypsum free Portland cement clinker with different percentages of Fe2O3 (5.68, 6.83, 8.02 ...

Composting Agricultural and Industrial Wastes

Thermochemical conversion of livestock wastes: carbonization of swine solids.

Slow pyrolysis or carbonization promotes the conversion of animal manures such as swine manure into charcoal. In this paper, the carbonizing kinetics of swine solids taken from different treatment stages were investigated with a thermogravimetric analyzer. Compared to their biologically stabilized counterpart (lagoon sludge) with an activation energy of 160 kJ mol(-1), the activation energies f...
