Estimation of gross calorific value of coal based on the cubist regression model [PDF]
Scientific ReportsThe gross calorific value (GCV) of coal is an important parameter for evaluating coal quality, and regression analysis methods can be used to predict GCV. In this study, we proposed a GCV prediction model based on cubist regression.

Jatropha curcas – Analysis of Gross Calorific Value
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2014 In recent years biofuels have obtained a considerable interest, due to the implementation of ruling and gradual replacement of fossil fuels. One of production steps at gaining the oil is a pressing process. Wastes come into being from this process. These

Prediction of gross calorific value from coal analysis using decision tree-based bagging and boosting techniques [PDF]
HeliyonThe calorific value of any fuel is one of the crucial parameters to grade fuel's burning capability. The bomb calorimeter has historically been used to calculate coal's gross calorific value (GCV).

Enhanced Thermal Safety of Hydrophobic SiO2 Aerogels Through Introduction of Layered Double Oxides [PDF]
GelsThis research enhances the thermal safety of hydrophobic silica aerogel (HSA) by integrating layered double oxides (LDOs). XRD and FTIR confirm that the introduction of LDOs does not affect the formation of SA.

Substitution of coking coal with biochar for thermal and metallurgical utilisation
International Journal of Sustainable Energy, 2022 To meet the global demand for energy, biochar can be a substitute and a green source of energy for fossil fuels and their derivatives. Biochar has its own supremacy to meet the requirements of the energy sector and replace coking coal for metallurgical ...
