摘要

In this study three kinds of biomass were investigated: wood biomass (pine), energy crop (Sida hermaphrodita) and agriculture biomass (straw) using the hydrothermal carbonization process (HTC). The HTC process was conducted in a specially designed reactor under the following conditions: 220 degrees C temperature and 4 h residence time. The solid (hydrochar) and liquid products of hydrothermal conversion were determined in terms of their chemical and physical properties. Futhermore, the basic parameters of the obtained hydrochars were established: ultimate and proximate analyses, higher heating value, mass and energy yield and energy densification ratio. The liquid products were analysed by measuring pH and conductivity, which confirmed their acidic and polar character, and Chemical Oxygen Demand (COD) at very high value indicating that the liquid phase contained a high concentration of organic matter and nutrients. Additionally, the TGA of hydrochar was performed in an air and inert atmosphere to simulate the combustion and pyrolysis process. Moreover, the pyrolysis process of the hydrochars was investigated using Py-GC-MS apparatus. The process was performed to analyze the composition of pyrolysis products from the hydrochars. The samples were pyrolyzed in sequence at 400, 500, and 600 degrees C with rapid heating and a short residence time. The pyrolysis of the hydrochars resulted in varied organic compounds dependent on the pyrolysis temperature and chemical composition of hydrochars.

7. This article presents a new numerical model describing the behaviour of a thermally thick wood sample exposed to high solar heat flux (above 1 MW/m2). A preliminary study based on dimensionless numbers is used to classify the problem and support model building assumptions. Then, a model based on mass, momentum and energy balance equations is proposed. These equations are coupled with liquid-vapour drying model and pseudo species biomass degradation model. By comparing to a former experimental study, preliminary results have shown that these equations are not enough to accurately predict biomass behaviour under high solar heat flux. Indeed, a char layer acting as radiative shield forms on the sample exposed surface. In addition to this classical set of equations, it is mandatory to take into account radiation penetration into the medium. Furthermore, as biomass contains water, medium deformation consecutively to char steam gasification must also be implemented. Finally, with the addition of these two strategies, the model is able to properly capture the degradation of biomass when exposed to high radiative heat flux over a range of sample initial moisture content. Additional insights of biomass behaviour under high solar heat flux were also derived. Drying, pyrolysis and gasification fronts are present at the same time inside of the sample. The coexistence of these three thermochemical fronts leads to char gasification by the steam produced from drying of the sample, which it is the main phenomenon behind medium ablation. [O] .
