Highlights ► Existing correlations for the calculation of the higher heating value(HHV) of the biofuels are selected. ► The HHV are evaluated with different formulae and compared to the experimental values. ► Error estimation are used to evaluate the accuracy of the different methods...
Highlights ► Coal desulfurization was modeled using General Regression Neural Networks (GRNN). ► The GRNN with spread of 0.3 was the best estimator for sulfur reduction. ► GRNN predicted organic and pyritic sulfur reduction with R 2 of 0.97 and 0.99.
Highlights ► Mo Co and W Ni catalysts supported on γ -alumina were made. ► Catalysts were filled in two-stage fixed beds for hydroprocessing of middle-temperature coal tar. ► Pressure and LHSV had obvious effects on hydrogenation performance. ► Heteroatoms in raw tar were greatly reduced...
Highlights ► Theoretical derivation of a new method to determining the biomass content of refuse derived fuels. ► Successful validation using defined mixtures of biogenic and fossil organic matter. ► High potential for routinely application of the developed method in the frame of the...
Highlights ► Study of environmental behavior of bus diesel engine with four vegetable oils. ► Comparison against the neat diesel fuel case. ► Reduction of smoke and slight increase of NO x with vegetable oil blends. ► Very slight increase of emitted CO and HC with vegetable oil blends....
Highlights ► Free fatty acids to biodiesel at high temperature is performed below critical point. ► Modeling of tall oil biodiesel fits autocatalytic and Arrenhius mechanisms. ► Autocatalytic reaction allows for low methanol to free fatty acid ratios.
Highlights ► Only single reorientation process dominates the interfacial properties in the presence of any electrolyte for 1 × 10 −6 mol L −1 377 solution. ► In the case of Gemini surfactant, the contribution of reorientation process at higher frequency decreases after the addition of...
Highlights ► Emissions of NO x and CO 2 were higher with biodiesel blends, while PM, CO, and HC emissions decreased with biodiesel blends. ► Higher NO x emissions obtained with increasing unsaturation of the biodiesel and PM reductions observed with the saturated blends. ► The biodiesel...
Highlights ► Major developments in hydrogen preparation and hydrogen storage application of carbon nanotubes. ► Application of CNTs as the catalyst support in hydrogen production. ► Challenges in optimization of the current state of hydrogen production and storage technologies. ► The...
Highlights ► In this work we investigate theoretically and numerically the nature of the evolution of a hot gas mixture containing polydisperse organic gel fuel droplets. ► The polydisperse spray is modeled using a Probability Density Function. ► We take into account the time evolution of...
