Boosting carbon efficiency of the biomass to liquid process with hydrogen from power: The effect of H2/CO ratio to the Fischer-Tropsch reactors on the production and power consumption
Ostadi, Mohammad; Rytter, Erling; Hillestad, Magne (Journal article; Peer reviewed, 2019)Carbon efficiency of a biomass to liquid process can be increased from ca. 30 to more than 90% by adding hydrogen generated from renewable power. The main reason is that in order to increase the H2/CO ratio after gasification ... -
Conceptual Design of a Once‐Through Gas‐to‐Liquid Process Combined with Ammonia Synthesis
Ostadi, Mohammad; Hillestad, Magne (Journal article; Peer reviewed, 2018)Recently, a new process has been proposed for a once‐through gas‐to‐liquid (GTL) plant suitable for offshore applications. Here, cogeneration of ammonia is suggested. This is firstly because the main ingredients for ammonia ... -
Enhancing the efficiency of power- and biomass-to-liquid fuel processes using fuel-assisted solid oxide electrolysis cells
Nielsen, Anders; Ostadi, Mohammad; Austbø, Bjørn; Hillestad, Magne; del Alamo Serrano, Gonzalo; Burheim, Odne Stokke (Journal article; Peer reviewed, 2022)Power- and biomass-to-liquid fuel processes (PBtL) can utilize renewable energy and residual forestry waste to produce liquid synthetic fuels, which have the potential to mitigate the climate impacts of the current ... -
Exergy Analysis of a Process Converting Power and Biomass to a Liquid Fuel
Ostadi, Mohammad; Austbø, Bjørn; Hillestad, Magne (Journal article; Peer reviewed, 2019)A power and biomass to liquid process (PBtL) via Fischer-Tropsch synthesis is exergetically analysed. Synthesis gas is generated through an entrained flow gasifier and extra hydrogen is produced through high temperature ... -
Improving carbon efficiency and profitability of the biomass to liquid process with hydrogen from renewable power
Hillestad, Magne; Ostadi, Mohammad; del Alamo Serrano, Gonzalo; Rytter, Erling; Austbø, Bjørn; Pharoah, Jon; Burheim, Odne Stokke (Journal article; Peer reviewed, 2018)A process where power and biomass are converted to Fischer-Tropsch liquid fuels (PBtL) is compared to a conventional Biomass-to-Liquid (BtL) process concept. Based on detailed process models, it is demonstrated that the ... -
New and Innovative Conceptual Designs of Gas-to-Liquid Processes
Ostadi, Mohammad (Doctoral theses at NTNU;2017:205, Doctoral thesis, 2017)The research is about a chemical process, which turns natural gas into liquid fuel through chemical reactions, and it is called Gas-to-Liquid (GTL) process. The produced liquid fuel is a replacement for liquid fuel derived ... -
Parametric Optimization of a Power and Biomass to Liquid Process
Ostadi, Mohammad; Austbø, Bjørn; Hillestad, Magne (Chapter, 2019)In this study, a power & biomass to liquid process (PBtL) is optimized with respect to nine continuous design variables. These variables have great impact on the profitability of the process. A detailed process model is ... -
Process Integration of Green Hydrogen: Decarbonization of Chemical Industries
Ostadi, Mohammad; Paso, Kristofer Gunnar; Rodriguez Fabia, Sandra; Øi, Lars Erik; Manenti, Flavio; Hillestad, Magne (Journal article; Peer reviewed, 2020)Integrated water electrolysis is a core principle of new process configurations for decarbonized heavy industries. Water electrolysis generates H2 and O2 and involves an exchange of thermal energy. In this manuscript, we ... -
Surrogate Models for Integrated Reforming Combined Cycle Optimization: Surrogat-modeller til optimalisering av naturgassbaserte kraftverk med integrert reformering
Ostadi, Mohammad (Master thesis, 2013)In the light of increasing concerns about climate change, greenhouse gas mitigation technologies have gained growing attention. Integrated Reforming Combined Cycle (IRCC) is one of the processes for reducing CO2 emissions ...
