Downdraft gasifier is a preferable method for carrying out biomass gasification because the produced gas has viable heating value with low tar content and can be cleaned to high purity, suitable for IC engine usage and chemical processing applications. This is due to throat section design in the...

The air-gasification of cassava rhizome mixed with Ni/α-Al2O3 catalyst in a drop tube reactor for production of fuel gas was carried out in this work. The conversion was performed at different temperatures from 873 to 1073 K, equivalence ratio (ER) of 0.2–0.6, and semi-continuous feeding of...

Metal based-zeolite catalysts were successfully prepared by two different methods including ion-exchange and wet impregnation. HZSM-5 synthesized by hydrothermal method at 160 °C was used as a support for loading metals including Co, Ni, Mo, Ga and Pd. The metal/HZSM-5 had surface area and...

Catalytic upgrading of the pyrolytic vapors after fast pyrolysis of Jatropha residue was performed using analytical pyrolysis–gas chromatography/mass spectrometry (Py–GC/MS) at 673–873 K. The Py–GC/MS analyses for pyrolysis vapors show a range of aromatic hydrocarbons, hydrocarbon...

HZSM-5 with high surface area of 625 m2/g was successfully synthesized by hydrothermal method at 160 °C for 72 h. The metal promoted on HZSM-5 catalyst was prepared by liquid ion exchange method. From XRD results, the addition of metals such as Co and Ni did not change the HZSM-5 structure....
