Experimental and modeling study of pinewood char gasification with CO2

The Outlook for Low-Grade Fuels in Tomsk Region: Research Experience at Tomsk Polytechnic University

“…Mentioned disadvantages can be eliminated by a heat processing of raw materials into energy products of acceptable quality, such as solid composite [8][9][10][11][12], liquid [13][14][15] or gaseous fuels [16][17][18]. Given the advantages of the gaseous fuels energy use (possibility of combustion process automating, ecological compatibility, low abrasive deterioration of heating surfaces and intensive heat transfer due to higher flow velocities available), the authors examined processing of low-grade raw material to a gaseous fuel.…”

Small Distributed Energy Russia: Combined Heat and Power Generation

“…It is thought that the gasification of solid fuel is actual and perspective direction of research, given that this technology is allows to use low grade fuels with producing of high quality gas and solid products [4][5][6]. The developments, reduced heat consumption for own needs by autothermal mode of gasification, are exist.…”

Kinetic modelling of char gasification by accounting for the evolution of the reactive surface area

“…(35) with (32) Sircar et al (2014) have highlighted that the structural parameter (ψ in Eq. (36)) of the random pore model increases with gasification temperature in many studies on biomass char gasification Consequently based on the relation (36) the activation energy of k 2 should be higher than the activation energy of k 1 .…”
