Pyrolysis is considered a promising way to treat sewage sludge and extract energy. This paper first studied the applicable conditions characteristics of high-ash (HASS) pyrolysis produce hydrogen-rich combustible gas. The yields three-phase products gas, tar, solid product HASS were determined. weight-loss behavior kinetic analyzed by thermogravimetric experiment. mainly decomposed at 540–901 °...

BACKGROUND Cigarette smoke is a primary risk factor for cardiovascular diseases. Enhanced function of the hemostatic system, in which platelets play a major role, is a significant underlying mechanism in cardiovascular disease and its progression. Epidemiological studies, complemented by physiological and biochemical data, show that cigarette smoke adversely affects platelet function, both in s...

Abstract Pyrolysis is a pathway for hydrogen reproduction from sewage sludge. The critical problem in the indirect pyrolysis process lower heat transfer performance furnace. circulation of media controls pyrolizer (e.g., carriers (HCs) form alumina balls), which essential determining and ultimately yield. temperature HCs amount yield are low because required vessel not satisfied. This study inv...

Trinidad has tar sand resources of about 2 billion barrels of oil on land in the Parrylands/Guapo and Brighton areas. With an oil price of over USD 25 per barrel, the commercial extraction of oil from Trinidad tar sands is viable, but it requires a careful study. The relatively small extent of this tar sand (about 10,000 acres and with depths varying from surface to less than 500 feet) and with...

Representative samples of smokers of regular middle tar and regular low tar cigarettes responded to a questionnaire concerning their smoking habits and participated in a blind product test, returning 24 hour butt collections from the smoking of both middle tar and low tar cigarettes. An estimate of the mouth intake of tar derived from a measurement of filter nicotine confirmed partial compensat...

Natural beta-phosphodiester 16mer and 15mer antisense oligonucleotides targeted against the HIV-1 and HIV-2 TAR RNAs respectively were previously described as sequence-specific inhibitors of in vitro retroviral reverse transcription. In this work, we tested chemically modified oligonucleotide analogues: alpha-phosphodiester, phosphorothioate, methylphosphonate, peptide nucleic acid or PNA, 2'- ...

In situ planar laser-induced fluorescence (PLIF) shows the effects of pyrolysis peak temperature and holding time on formation 3–5 rings polyaromatic hydrocarbons (PAHs) in vapour phase during biomass samples.
