The K2CO3-based sorbent is promising for CO2 capture from the flue gas of fossil-fuel-fired power plant. In this work, various support/binder materials were utilized to prepare K2CO3-based sorbent pellets by an extrusion method, and their mechanical strength and CO2 capture performance were...

This article follows the development of early UCG (underground coal gasification) ideas. Historical facts are discussed mainly from the technological perspective and early experiments in UCG are analyzed. Our search for the first successful UCG experiment brings to light a new finding, which was...

In the present study, propagation of a gasification flame through a coal channel is considered. A simplified physical model incorporating all of the main physical factors determining the flame front propagation in a gasification reactor is suggested. It is demonstrated that the flame...

Widespread commercialization of PCM-based latent heat storage systems is limited by the low melting and solidification rates during the phase transition process. In this study, fins are used to enhance the phase change process. A parametric study is conducted to understand the effect of fins on...
