Hydrogen production from lignin, cellulose and waste biomass via supercritical water gasification: Catalyst activity and process optimization study

Development of Heterogeneous Catalysts for Thermo-Chemical Conversion of Lignocellulosic Biomass

“…The literature data demonstrate that Ni-based systems are also most popular in this case [84][85][86][87]. In fact, promising results were obtained for catalysts containing noble metals as well [88].…”

Hydrogen generation via supercritical water gasification of lignin using Ni-Co/Mg-Al catalysts

“…All the SCWG tests were performed under the operating conditions of 650 °C, 26 MPa and water to biomass mass ratio of 5. 650 °C was fixed as the operating temperature because in our previous work, it was found that the increase in reaction temperature from 450 °C to 650 °C could significantly increase the hydrogen yield from SCWG of different biomass feedstock no matter homogeneous or heterogeneous catalyst was used . For each test, 0.65 g lignin, 0.65 g catalyst, and 3.25 g water were used.…”

Current state and future prospects for liquid biofuels in Canada

“…The University of Calgary in collaboration with McGill University are looking at catalytic gasification of biosolids (Arnold et al, 2017) while University of Saskatchewan and York University are looking at gasification of horse manure, fruit wastes, and agro-food residues using supercritical water gasification (Nanda et al, 2016). Supercritical gasification is another area that is receiving attention at the academic level in Canada at several institutions, including the University of Saskatchewan (Kang et al, 2016) and University of Western Ontario (Behnia et al, 2016), as the use of supercritical water increases diffusion coefficients and reaction rates in the gasifier. Finally, low cost catalysts are being explored at University of British Columbia, such as Fenton's reagent combined with red mud for the secondary cracking reformation of tar and char gasification (Yang et al, 2017).…”
