Abstract As coalbed methane (CBM) becomes an increasingly important resource in the global natural gas market, gas transport in CBM reservoirs remains a crucial research topic that has not been fully understood. Gas migration in coal matrix is identified as a diffusion process which is quantified by effective diffusivity. This paper aims to explore the diffusion process in coal and measure the effective diffusivity using X-ray microcomputed tomography (micro-CT) imaging. By visualising the krypt...

Abstract A new diffusion model is developed to study the mass diffusion of CO2 in the water-oil liquid system. The diffusion stages are divided by the position of diffused CO2 front in the liquid system. The 1st and 2nd diffusion stages are performed to characterize the CO2 diffusion in individual oil phase and in water-oil liquid system, respectively. The Peng-Robinson equation of state combined with the diffusion model of two stages are developed to describe the diffusion process of CO2 in the...

Abstract Fast and slow pyrolysis are good means of biomass transformation. Studying the formation of bio-char is not only helpful to intensify the transformation of biomass, but also to improve its performance. However, little work has been reported on the similarities and differences of bio-chars in fast and slow pyrolysis. We investigated the fast and slow pyrolysis of walnut shell at 400–800 °C to find the evolvement law of bio-char. It was found that the formation mechanism of bio-char in fa...

Abstract The paper focuses on the implementation of a comprehensive and robust optimization procedure for a synthesis gas fired four-cylinder, spark ignited, 2.2 L industrial engine used in combined heat and power applications. Innovatively designed workflow is for the first time incorporating also a thorough operational stability analysis for evaluation of the engine operation durability while using off-design fuels. Design constraints of the engine operational space are set after in depth inve...

Abstract Selected agricultural and energy crop biomass ashes represented by two mixed cereal straws, corn straw, Miscanthus × Gigantus and Salix Viminalis were chosen for ash behaviour investigation and prediction of operating problems during biomass combustion. The presence of aggressive species in the ash generate operational problems of heat exchanging surfaces in power boilers connected with slagging and fouling processes, limiting the use of biomass direct combustion for energy production. ...

Abstract This study aims to differentiate between bacteria-algae interactions and thermal maturation, at the same time, shed light on the hydrocarbon generation pathways based on chemical changes at the submicron scale. For this goal, samples were taken from the lower shale member of the Bakken Formation in Willison Basin at the early and peak thermal maturity stages and analyzed with surface probes. Sample selection was based on bulk geochemical screening, organic petrology and fluorescence emi...

Abstract In this study, the changes in cycle to cycle variations and correlation coefficient between main combustion parameters were revealed by usage of biodiesels produced from different raw materials and bioethanol-biodiesel-diesel ternary blends under three different engine loads and constant engine speed in a direct injection heavy duty diesel engine. The results showed that maximum cylinder gas pressure (Pmax) values of the chicken fat biodiesel (CFB) and fleshing oil biodiesel (FOB) were ...

Abstract Developing sustainable, efficient and cost-effective materials for adsorptive desulfurization is highly important. Herein, macroscopic 3D boron nitride (BN) monolith has been controllable prepared, with commercial melamine sponge as a template, for the first time and employed for adsorptive desulfurization. By virtue of the 3D framework of melamine sponge, the as-prepared 3D BN monolith inherited the features of high porosity, superelasticity and low density. Compared with the BN powder...

Abstract Oil-laden biofuel intermediate (BI) from flash-hydrolyzed microalgae was characterized, pyrolyzed, and subjected to catalytic transfer hydrogenation (CTH) to produce both gaseous and liquid hydrocarbon fuels. The BI was characterized by TGA and FTIR that revealed significant triglyceride, evidenced by C O bond with insignificant level of carbohydrates and proteins. Thermogravimetric analysis (TGA) indicated that the BI could be thermally decomposed at 400 °C. Pyrolysis of the BI engende...

Abstract In situ oil shale conversion experiments have revealed that to efficiently obtain shale oil, factors such as heating temperature, products, and matter thermal evolution of organic matter during heating need to be optimized. In this study, oil shales from China were subjected to retorting experiments involving eight heating steps. During steps I-II (≤300 °C), the expelled product is mainly water, the hydrocarbon generation potential (PP) of the samples was extremely high, and the organic...
