Arsenic poisoning is a worldwide endemic disease that affects thousands of people. Growing evidence from animal, cell, and human studies indicates that arsenic has deleterious effects on the immune system. The present investigation is a population-based study that observed changes in the proliferation of human T-cells and IL-2 and INF-γ mRNA expression. Our results show that coal-burning arsenic can...
The hydrogasification of coal and polyethylene (PE) mixtures was carried out at 1073K under 7.1MPa of hydrogen. The product distribution and temperature profile were analyzed. The yield of methane reached 90% (carbon basis) after 80s when PE was used alone. A significant synergistic effect was found when coal and PE were mixed and used in hydrogasification. This synergistic effect may have been partly...
Rapid pyrolysis of Taiheiyo coal was investigated with a laboratory-scale batch type reactor (BTR), which was specially developed to study various gasification processes at the conditions close to an industrial entrained bed gasifier. The experiments were carried out in helium at 1073K, 7.1MPa, varying reaction times from 1 to 80s and coal/gas ratios in the range of 0.41-1.65g/l. Extents of pyrolysis...
