“…Conversely, an increase in volatile matter (VM) typically decreases in HHV because these compounds have a lower energy content. These findings are supported by Parnthong et al Furthermore, it is observed that a lower ash content correlates with higher HHV. Ash represents incombustible material within the biomass; thus, a higher ash content dilutes the combustible portion, reducing the calorific value.…”

“…These reactions lead to the formation of a solid product with a significantly higher carbon content compared with the original feedstock. 39 Ramke et al 40 and Parnthong 41 propose that this technique relies on a straightforward chemical process, where the exothermic dehydration of carbohydrates and the heat emitted by the exothermic reactions within the reactor contribute to maintaining the required temperature during the carbonization process. As a result, the energy consumption for maintaining the reactor temperature is substantially reduced.…”

The Valle del Cauca region in Colombia is a significant producer of sugar cane, resulting in large quantities of agricultural residues (green harvesting residues (GHRs)). To ensure sustainable management of these residues, it is crucial to implement proper treatment and disposal technologies while also reusing waste to produce biogas, bioelectricity, or biofuels. The biomass hydrothermal carbonization process offers a means to convert these residues into useful products that serve as fuels or valuable energy materials. This thermal treatment involves the use of water as a solvent and reagent within the biomass's internal structure. In this study, sugar cane cutting residues were collected with relatively high moisture content of 8.5% wt. These residues were subjected to carbonization temperatures ranging from 200 to 300 °C, along with water/GHR ratios between 5/1 and 10/1. The properties of the resulting hydrocarbons were analyzed by using proximate and ultimate analysis. The objective was to produce hydrochar samples with the highest higher heating value (HHV) and energy density compared with the GHRs. The HHV value of the hydrochar showed a significant increase of 69.6% compared with that of the GHRs, reaching 43.5 MJ/kg. Besides, process parameters were optimized for mass yields, energy yields, and ash content. This exploration led us to investigate a new temperature range between 280 and 320 °C, allowing us to establish an optimal value for the hydrochar's properties.

“…Sugar is a globally significant food product, with over 178 million tons produced in 2019, indicating a 4.7 % growth from 2017 [ 1 ]. Thailand ranks fourth in both sugar production and exports, primarily relying on sugarcane as the raw material [ 2 ]. However, the substantial waste generated from sugarcane production, including bagasse, tops, and leaves (28 %, 17 %, and 30 % of total byproducts, respectively), poses environmental challenges.…”

“…Like biomass in general, wood biomass contains lignocellulosic content such as cellulose, hemicellulose, and lignin [1][2][3]. These contents commonly consist of some abundant elements such as carbon, hydrogen, and oxygen, as well as some less abundant elements such as nitrogen and sulfur [4][5][6]. Based on this abundant composition, it has the potency to be utilized for converting it into a more valuable product by the decomposition process.…”

The plasma-assisted pyrolysis process is a powerful treatment for converting wood biomass to graphitic carbon. In order to make this process more precise and effective in time, the rate of graphitization data is needed, especially for predicting the effective time of treatment. In this study, numerical analysis is conducted to predict the rate of graphitization. An explicit finite difference method is applied for the numerical analysis. Some initial parameters used are the wood thickness (5 mm), coefficient of diffusivity (0.082 mm2/s), input plasma temperature (4,000 C), initial wood temperature (35 C), and room temperature (27 C). The analysis was conducted with a variation of time differences of 1 s, 2 s, 3 s, 4 s, and 5 s. The assumption used in this analysis is that the minimum temperature for graphitic carbon conversion is 2,000 C. The result of this study is the values of graphitization rates and exposure times summarized in TABLE 1. Therefore, this numerical analysis can successfully be used to predict the rate of graphitization and plasma exposure time for different wood biomass thicknesses.
