The effects of adding ash-free coal (AFC) as a binder on the physical and chemical properties of coke were investigated to understand the mechanism of coke strength increase and to measure CO conversion reactivity. Two AFC samples (AFC_P and AFC_E) were first extracted from Indonesian low-rank coal. Torrefied biomass was also produced from woody biomass for use as an additive to AFC samples. Coke...
The corrosion characteristics of aluminum alloys were investigated in the bio-ethanol gasoline blended fuel at 100°C. The corrosion property of aluminum alloys was evaluated by an in situ 2-electrode electrochemical impedance spectroscopy (EIS), weight loss test and pressure–time measurement. Surface analysis was carried out after immersion test. The polarization resistance of aluminum alloys was...
