“…Coupling biochemical conversion of biomass, which depletes the polysaccharide fraction, with pyrolysis of the resulting residue, or bagasse, is another avenue to explore further (Islam et al, 2010;Cunha et al, 2011). Torrefaction is a low-temperature (200-400°C) thermal pretreatment that decomposes hemicellulose and may segregate disfavored products such as water and acid into intermediate streams before the next stage of pyrolysis (Zheng et al, 2013).…”

Thermal conversion of biomass is a rapid, low-cost way to produce a dense liquid product, known as bio-oil, that can be refined to transportation fuels. However, utilization of bio-oil is challenging due to its chemical complexity, acidity, and instability -all results of the intricate nature of biomass. A clear understanding of how biomass properties impact yield and composition of thermal products will provide guidance to optimize both biomass and conditions for thermal conversion. To aid elucidation of these associations, we first describe biomass polymers, including phenolics, polysaccharides, acetyl groups, and inorganic ions, and the chemical interactions among them. We then discuss evidence for three roles (i.e., models) for biomass components in the formation of liquid pyrolysis products: (1) as direct sources, (2) as catalysts, and (3) as indirect factors whereby chemical interactions among components and/or cell wall structural features impact thermal conversion products. We highlight associations that might be utilized to optimize biomass content prior to pyrolysis, though a more detailed characterization is required to understand indirect effects. In combination with high-throughput biomass characterization techniques, this knowledge will enable identification of biomass particularly suited for biofuel production and can also guide genetic engineering of bioenergy crops to improve biomass features.

“…The bio-oil viscosity measured at 40ºC in this study was ten-fold lower than the viscosity (0.02 Pa.s) of the bio-oil produced from (heterotrophic) microalgae (Miao & Wu, 2004). The viscosity of bio-oils produced from different feedstocks though MAP was lower than the light fuel viscosity of 4 cSt (Mohan et al, 2006), the heavy fuel oil viscosity of 50 cSt (Czernik and Bridgwater, 2004), the US #4 fuel oil viscosity of 5.5-24 cSt (Oasmaa et al, 2009), commercial automotive #2 diesel viscosity of 2-4.5 cSt (Islam et al, 2010), diesel viscosity of 0.011 Pa s (Thangalazhy-Gopakumar et al, Fig. 3.…”

“…Viscosity of bio-oils produced from different feedstocks at indicated temperatures www.intechopen.com 2010), and was higher than JP4 viscosity of 0.88 cSt (Chiaramonti et al, 2007) and gasoline viscosity of 0.006 Pa s (Thangalazhy-Gopakumar et al, 2010) at a temperature of 40ºC. Considering the viscosity criteria (15 cSt at 35-45ºC and 21.5 cSt at 30ºC) presented by researchers (Pootakham & Kumar 2010a;Islam et al, 2010) for loading/handling and pipe transportation, the bio-oils from different feedstocks produced through MAP can be easy to load using existing petroleum loading equipments and easy to transport through pipe also. According to ASTM burner fuel standard, the bio-oil can have a maximum viscosity of 125 cSt at 40ºC without filtering (Oasmaa et al, 2009).…”

“…Thermal gravimetric analysis (TGA) studies [7][8][9][10] performed at a constant heating rate show the bulk of mass loss occurs from 200 to 400°C with char yields (on an ash-free basis) of about 15-20% when the temperature exceeds 500°C. Tube furnace studies [11,12] achieved higher yields at temperatures of 500°C and char yields were further enhanced when extremely high heating rates and short heating times were employed, but this was indicative of only partial decomposition of the biomass material rather than a change in the reaction mechanisms. Pretreatment of SCB with soluble chemical additives [7,13,14] show that mass-loss events during pyrolysis are initiated at lower temperatures and result in greatly enhanced char yields compared to untreated SCB.…”

The purpose of this research was to study the conditions that maximize the formation of char when sugar cane bagasse (SCB) is pyrolysed. It has been proposed that char produced from biomass may be crushed and then suspended in water to produce a char-water fuel suitable as a heavy oil replacement. Experiments were conducted by thermal gravimetric analysis (TGA) and Fourier transfer infrared spectrometry (FTIR) to measure the effect of the chemical additives diammonium phosphate (DAP) or monoammonium phosphate (MAP) on the mass-loss processes of SCB when heated between 100°C and 700°C under nitrogen. The additives were impregnated on the SCB as aqueous solutions at concentrations of between 0.01M and 1.0M. For untreated bagasse, char yield was 18wt% at 400°C and 16.5wt% at 700°C. For treated SCB, it was observed that the additives initiated mass loss at lower temperatures and produced significantly larger yields of char than untreated bagasse. When heated to 450°C, the char yield increased with additive concentration. If heated above 450°C, another mass loss occurred between 450°C and 600°C, but only for those SCB samples treated with additives at concentrations greater than 0.1M. Thus, when heated to 700°C the maximum yield of char occurred for SCB sample treated with 0.1M additives. Analyses of the evolved pyrolysis gases using FTIR showed that treated SCB, at concentrations greater than 0.1M DAP or MAP, contained less hydrocarbon species and were enriched in water consistent with the catalytic degradation of the SCB. When treated with higher concentrations of additives, gases that evolved at temperatures above 450°C were rich in phosphoric acid esters and aromatic and unsaturated phosphonic acid species.
