Hydrothermal gasification is a promising technology for converting biomass into syngas (H
2/CO). A substantial challenge of hydrothermal gasification for producing hydrogen is the …

With the increase in the world population and economic activity, the production of sewage
sludge has grown, and its management has become an environmental problem. The most …

To produce H 2-rich gas, steam gasification of spent coffee grounds is performed in this
study by applying Zr x Ce 1-x O 2 supports (x= 0.2, 0.6) in a monolithic reactor. Compared …

The paper presents a critical analysis of a commercial pre-feasibility study for hydrogen
generation from sewage sludge generated in a wastewater treatment plant sized Population …

Tannery sludge (TS) is a harmful, hazardous byproduct of the leather processing industry.
This industrial solid waste generally undergoes uncontrolled landfilling and pollutes the …

Catalytic tar cracking is a promising technique for hot syngas cleaning unit in gasification
plants because it can preserve tars chemical energy, so increasing the syngas heating …

Sewage sludge is solid waste resulting from wastewater treatment processes, and its
improper management adversely affects the environment and human health. This study …

This study attempts to find active and stable catalysts for H 2 production from catalytic
methane decomposition (CMD). Experimental results show that metal-based (Ni, Fe, and Ni …

The continuous tightening of legislation regulating the agricultural usage of sewage sludge
in the province of Catalonia (Spain) leads us to propose its gasification to produce hydrogen …

Hydrochar was produced from sewage sludge via the hydrothermal carbonization (HTC)
process. The effects of carbonization temperature (150–300° C), solid load (10–30%), and …
