“…Thus, H 2 production using SCWG provides a more sustainable and environmentally friendly alternative in the future. 19 In this study, the SCWG of real-life biomass in the presence of catalysts is performed. The purpose of this research is to gasify HTL CH and compare the results with HTL CM using SCW in the presence of catalysts is due to the fact that it has previously proved effective for the production of H 2 in SCWG processes.…”

In this article, supercritical water gasification of biocrude at different conditions was performed and compared to each other. Three scenarios were considered while treating biocrude originating from cattle manure (CM) and corn husk (CH), namely, uncatalyzed feedstock, catalyzed with 10% Ni–0.08% Ru/Al2O3 and finally catalyzed with 10% Ni–0.08% Ru/Al2O3–ZrO2. It was found that 10% Ni–0.08% Ru/Al2O3–ZrO2 has performed significantly better than the other two scenarios over the 5 hour run time with a 193 and 187% higher hydrogen yield compared to the uncatalyzed and 10% Ni–0.08% Ru/Al2O3 catalyzed scenarios, respectively. Compared to CM gasification in the presence of a 10% Ni–0.08% Ru/Al2O3–ZrO2 catalyst, the catalyst got deactivated because of the high phenol and furan content in the corn husk biocrude, therefore hydrogen yield performance fell significantly. It was observed that the carbon gasification efficiency of the biocrude was independent of temperature. In terms of carbon conversion, the equilibrium conditions for the biocrude considered were attained at lower temperature. A mechanistic model based on the Eley–Rideal method was devised and tested against the obtained data. The dissociation of adsorbed oxygenated hydrocarbon is found to be the rate-determining step with an average absolute deviation of 3.55%.

A parametric study through the modelling of hydrothermal gasification for hydrogen production from algal biomass

Hydrothermal gasification (HTG) is applicable to high moisture content biomass feedstock such as wet microalgae. The key interests of this thermochemical processing are its ability to use whole algae instead of simply lipid extracts and to use a wide range of algal feedstocks. It employs water in the form of a reaction medium to disintegrate biomass into hydrogen gas. The products' composition and yields are a function of process parameters, namely feed concentration, pressure, and temperature. There is very limited literature available on model development to understand the impacts of various input parameters on the products of HTG. This study presents development of a detailed process model for HTG and the illustration of process parameters on the gas product yields. The approach includes developing the system model, identifying the key process parameters in the reactor setup that affect syngas yield, and understanding the overall process in terms of final product yield. A simulation of hydrothermal gasification based on thermodynamic equilibrium is studied. Based on the developed process model about 52.1 t/day of hydrogen can be produced from 500 t/day of wet algal biomass. This shows the potential of large-scale hydrogen production through this process for hydrogen economy.The results from this study could be used by the gas processing industry and policymakers to determine the most feasible means of converting biomassbased resources into gaseous fuels.
