Study on the thermal stability of the bio-oil components by Py-GC/MS

open access: yesEnergy Reports, 2023
Pyrolysis-gas chromatograph/mass spectrometry (Py-GC/MS) was used to study the thermal stability of the bio-oil components as the pyrolysis temperature increased from 100 °C to 550 °C. The peak area changes of 66 typical compounds identified by GC/MS are

Assessment of coal gasification in a pressurized fixed bed gasifier using an ASPEN plus and Euler–Euler model

open access: yesInternational Journal of Coal Science & Technology, 2020
With the help of Aspen Plus, a two-dimensional unsteady CFD model is developed to simulate the coal gasification process in a fixed bed gasifier. A developed and validated two dimensional CFD model for coal gasification has been used to predict and ...
