Fouling in heat exchangers not only reduces heat transfer performance significantly, but also causes considerable pressure drop, resulting in higher pumping requirements. It would be much more desirable if surfaces which are inherently less prone towards fouling could be developed. In this paper, autocatalytic Nickel–Phosphorus–Polytetrafluoroethylene (Ni–P–PTFE) composite coatings and modified diamond-like...
Cellulose was extracted from cotton stalk and characterized by using scanning electron microscope (SEM), X-ray diffraction (XRD), nuclear magnetic resonance (NMR), and Fourier transform infrared (FTIR) spectroscopy. The results showed that the extracted cellulose had representative cellulose structure. Furthermore, the extracted cellulose was converted into liquid oil by direct deoxy-liquefaction...
In a series of two papers chemical looping combustion (CLC) of two Victorian brown coals (Loy Yang and Morwell) were investigated using CuO as oxygen carrier. The experiments were conducted using a thermogravimetric analyzer (TGA) under CO 2 gasification environment with CuO. This first paper reports the assessment of interaction between CuO and minerals inherent in coals during one reduction...
This paper is part two in a series of two papers on chemical looping combustion using Victorian brown coal. Part one described the assessment of interaction between CuO and minerals inherent in two Victorian brown coals during one cycle CLC experiments with CuO. This second paper describes the assessment of performance of CuO with the same two coals but in multicycle operations. The chemical and physical...
