Bed packing configuration and hot-spot utilization for low-temperature CO2 methanation on monolithic reactor
Huynh, Huong Lan; Tucho, Wakshum Mekonnen; Shen, Qi; Yu, Zhixin (Peer reviewed; Journal article, 2022)The revival of CO2 methanation (Sabatier reaction) as part of the large-scale Power-to-Gas technology has stimulated the development of novel reactor concepts for better heat management due to its exothermic nature. The ... -
CO2 methanation on hydrotalcite-derived catalysts and structured reactors: A review
Huynh, Huong Lan; Yu, Zhixin (Peer reviewed; Journal article, 2020)CO2 methanation reaction has attracted renewed interest since the power-to-gas (PtG) concept emerged as a promising alternative for CO2 emission abatement using surplus renewable electricity. Although the reaction has been ... -
CO2 methanation on Ni-Fe based catalysts: Mechanistic and structured reactor study
Huynh, Huong Lan (PhD thesis UiS;607, Doctoral thesis, 2021-10)The clean energy transition towards renewable energy sources has increased the need for large-scale and long-term energy storage systems. Power-to-Gas concept offers the solution to convert surplus electrical power into ... -
Promoting effect of Fe on supported Ni catalysts in CO2 methanation by in situ DRIFTS and DFT study
Huynh, Huong Lan; Zhu, Jie; Zhang, Guanghui; Shen, Yongli; Tucho, Wakshum Mekonnen; Ding, Yi; Yu, Zhixin (Peer reviewed; Journal article, 2020-12)Bimetallic NiFe catalysts have emerged as a promising alternative to the traditional Ni catalysts for CO2 methanation. However, the promoting effect of Fe on the bimetallic catalysts remains ambiguous. In this study, a ... -
Structured NiFe catalysts derived from in-situ grown layered double hydroxides on ceramic monolith for CO2 methanation
Huynh, Huong Lan; Tucho, Wakshum Mekonnen; Yu, Zhixin (Peer reviewed; Journal article, 2020)Monolithic catalysts for CO2 methanation have become an active research area for the industrial development of Power-to-Gas technology.

Synthetic natural gas production from CO2 and renewable H2: Towards large-scale production of Ni–Fe alloy catalysts for commercialization
Huynh, Huong Lan; Tucho, Wakshum Mekonnen; Yu, Xinhai; Yu, Zhixin (Peer reviewed; Journal article, 2020-08)Synthetic natural gas (SNG) is one of the promising energy carriers for the excessive electricity generated from variable renewable energy sources. SNG production from renewable H2 and CO2 via catalytic CO2 methanation has ... -
Tuning the interfacial sites between copper and metal oxides (Zn, Zr, In) for CO2 hydrogenation to methanol
Stangeland, Kristian; Navarro, Hans Herrera; Huynh, Huong Lan; Tucho, Wakshum Mekonnen; Yu, Zhixin (Peer reviewed; Journal article, 2021)The influence of different metal oxides (ZnO, ZrO2, In2O3) in CO2 hydrogenation to methanol over Cu-based catalysts was studied. The catalysts were characterized using x-ray diffraction (XRD), thermal gravimetric analysis ...
