“…Biomass-burning aerosols were predominantly fine particles (PM 2.5 ), which constitute a high proportion of PM 10 concentration. The PM 2.5 /PM 10 ratio at Xiamen Bay in China (Li et al, 2013), Thailand (Oanh et al, 2011), Korea (Ryu et al, 2007), and central Taiwan (Cheng et al, 2009) were found to be as high as 90, 79, 90 and 80%, respectively. Note that these findings are close to the simulated results in this study.…”

“…Because OC is predominantly emitted from biomass burning, biomass-burning particles have relatively high OC / EC ratios and are generally well correlated with biomass burning tracers (Cao et al, 2008;Cheng et al, 2008;Popovicheva et al, 2014). The lack of significant increases in OC / EC ratio (2.4 ± 0.4), and OC and levoglucosan concentrations during the Chinese haze episode compared with nonepisode measurements suggests that the elevated K + concentrations observed during the Chinese haze episode might be due to emissions from other sources, such as soil, sea salt, or industrial complexes.…”

Abstract. Extensive forest fires occurred during late July 2014 across the forested region of Siberia, Russia. Smoke plumes emitted from Siberian forest fires underwent long-range transport over Mongolia and northeast China to the Korean Peninsula, which is located ∼ 3000 km south of the Siberian forest. A notably high aerosol optical depth of ∼ 4 was observed at a wavelength of 500 nm near the source of the Siberian forest fires. Smoke plumes reached 3-5 km in height near the source and fell below 2 km over the Korean Peninsula. Elevated concentrations of levoglucosan were observed (119.7 ± 6.0 ng m −3 ), which were ∼ 4.5 times higher than those observed during non-event periods in July 2014. During the middle of July 2014, a haze episode occurred that was primarily caused by the long-range transport of emission plumes originating from urban and industrial complexes in East China. Sharp increases in SO 2− 4 concentrations (23.1 ± 2.1 µg m −3 ) were observed during this episode. The haze caused by the long-range transport of Siberian forest fire emissions was clearly identified by relatively high organic carbon (OC) / elemental carbon (EC) ratios (7.18 ± 0.2) and OC / SO 2− 4 ratios (1.31 ± 0.07) compared with those of the Chinese haze episode (OC / EC ratio: 2.4 ± 0.4; OC / SO 2− 4 ratio: 0.21 ± 0.05). Remote measurement techniques and chemical analyses of the haze plumes clearly show that the haze episode that occurred during late July 2014 was caused mainly by the long-range transport of smoke plumes emitted from Siberian forest fires.

“…The open burning of biomass is a significant source of CO 2 , CH 4 , and N 2 O, as well as other pollutants such as NO x , CO, and volatile carbon compounds [43]. This waste gas is one of the prime concerns of the scientists in the twenty-first century.…”

Biofuel produced by fast pyrolysis from biomass is a promising candidate. The heart of the system is a reactor which is directly or indirectly heated to approximately 500 ∘ C by exhaust gases from a combustor that burns pyrolysis gas and some of the byproduct char. In most of the cases, external biomass heater is used as heating source of the system while internal electrical heating is recently implemented as source of reactor heating. However, this heating system causes biomass or other conventional forms of fuel consumption to produce renewable energy and contributes to environmental pollution. In order to overcome these, the feasibility of incorporating solar energy with fast pyrolysis has been investigated. The main advantages of solar reactor heating include renewable source of energy, comparatively simpler devices, and no environmental pollution. A lab scale pyrolysis setup has been examined along with 1.2 m diameter parabolic reflector concentrator that provides hot exhaust gas up to 162∘ C. The study shows that about 32.4% carbon dioxide (CO 2 ) emissions and almost one-third portion of fuel cost are reduced by incorporating solar heating system. Successful implementation of this proposed solar assisted pyrolysis would open a prospective window of renewable energy.
