A new mathematical model is proposed for the estimation of CO2 gasification kinetics of different rank coals and ash contents. There are no previous reports on the determination of the conversion rate or even residence time of CO2 or steam gasification based on coal characterization and for a...

A comparative study on CO2 gasification kinetics of flax straw char produced by two different processes, namely, torrefaction and pyrolysis was investigated using a TGA (thermogravimetric analyzer). The objective of this research was to investigate the diffusion and surface reactions that occur...

Low-temperature oxidation (LTO) of the Fosterton crude oil mixed with its reservoir sand has been investigated in a tubular reactor. Reservoir sand saturated with 15wt% of crude oil (20.5° API gravity) was subjected to air injection at low-temperature (220°C) for a period of time (17h and...

ISC (in situ combustion) based enhanced heavy oil recovery is complex because there are numerous chemical reactions taking place simultaneously. The complexity arises due to the immense number of components reacting through many different reaction paths where the geology and oil saturation vary...
