Integrating the circular economy model into the management and treatment of Fischer–Tropsch effluents—a conversion of waste to energy (biogas) opportunity

IET Renewable Power Generation, Volume 18, Issue 16, Page 4153-4165, 7 December 2024.
The review promotes the use of circular economy principles. This review investigates ameliorative measures to overcome the limitations of biological treatment methods for FT effluents. Abstract The Fischer–Tropsch (FT) process converts coal, biomass, or natural gas into liquid hydrocarbons via syngas generation and catalytic conversion.

Stability analysis of hyperbolic coal pillars with peeling and high temperature effects

Energy Exploration & Exploitation, 2020
In this present study, a twice-peeling model was established to analyze the hyperbolic coal pillars stability in underground coal gasification and then propose the concept of stripping degree to show model details for numerical simulation. The data shows

Modeling radiation in particle clouds: On the importance of inter-particle radiation for pulverized solid fuel combustion [PDF]

arXiv, 2014
The importance of inter-particle radiation for clusters of gray and diffuse particles is investigated. The radiative cooling of each individual particle is found to vary strongly with its position in the cluster, and a mean radiative particle cooling term is proposed for single particle simulations of particle clusters or for high detail simulation ...
