CATALYTIC C-O BOND CLEAVAGE TO SELECTIVELY PRODUCE VALUABLE CHEMICALS FROM BIOMASS-DERIVED FURANIC COMPOUNDS USING NI-BASED CATALYSTS
… develop catalytic systems for C-O hydrogenolysis based on non-noble metals due to the high cost and depleting resources of noble metals. In this thesis, we investigated different catalytic systems composing of zeolite-supported Ni catalysts and bimetallic Ni-WOx catalysts, to get more insights …

Ni Stability in Anion Exchange Membrane Fuel Cells
… reliance on expensive platinum group metal (PGM) catalysts. An anion exchange membrane fuel cell (AEMFC) is one of many alternatives. The AEMFC provides an alkaline environment that enables the use of many non-platinum group metal (non-PGM) catalysts. This grants AEMFCs the potential to become …

Transition Metal Heterogeneous Catalysis Towards Applications in Sustainable Energy: Leveraging Rational Design Principles for Activity, Stability, and Stereoselectivity
… energy storage applications including liquid organic hydrogen carriers (LOHCs). The methanol oxidation reaction (MOR) is a multistep reaction comprised of methanol dehydrogenation leading to CO adsorbed on the catalyst surface, followed by CO oxidation. Incorporation of an oxophilic material that …

Supercritical water gasification of lignocellulosic biomass materials for hydrogen production
… comprising of cellulose, hemicellulose and lignin were selected as the feedstock for SCWG process optimization. The objective of the study was to optimize the process conditions, propose a detailed reaction pathway for model compounds and understand how each intermediate product behaves under …

Dry reforming of associated natural gas using catalytic membrane reactors.
… in the atmosphere. Associated natural gas containing high concentrations of CO2 and C3H8 could therefore be utilized for hydrogen and synthesis gas (syngas) production in the near future, without need for the removal of CO2 from the source gas. Thus, the DRP reaction is a suitable process to …

Industrial Ni-Based Catalyst Development for Carbon Dioxide Reforming of Methane
… in three main phases. In the first phase, Ni and Co monometallic and Ni-Co bimetallic catalysts were prepared by using both co-precipitation and impregnation methods. Cylindrical and spherical shaped catalysts were made using the Ni-Co bimetallic catalyst with and without the addition of …
