Jankovic, T.J. (author), Straathof, Adrie J.J. (author), McGregor, Ian R. (author), Kiss, A.A. (author)Distillation is the most used separation technology at industrial-scale, but using distillation in bio-based processes (e.g. fermentation processes to produce bioethanol) is quite challenging when mild temperatures are needed to keep the microbes alive. Vacuum distillation can be used to perform evaporation at low temperatures, but setting a...journal article 2024

Vaquerizo, L. (author), Kiss, A.A. (author)Methanol and DME are highly efficient fuels and relevant building blocks that can be synthesized by CO<sub>2</sub> hydrogenation. While several alternatives for methanol production by CO<sub>2</sub> hydrogenation have already been developed at a commercial scale, DME production is still based on methanol dehydration. In this sense, the...journal article 2024

Luo, J. (author), Pérez-Fortes, Mar (author), Ibarra Gonzalez, P. (author), Straathof, Adrie J.J. (author), Ramirez, Andrea (author)Combining intermittent renewable electricity (IRE) with carbon capture and utilisation is urgently needed in the chemical sector. In this context, microbial electrosynthesis (MES) has gained attention. It can electrochemically produce hexanoic acid, a value-added chemical, from CO<sub>2</sub>. However, there is a lack of understanding...journal article 2024

Li, Q. (author), Finn, Adrian J. (author), Doyle, Stephen J. (author), Smith, Robin (author), Kiss, A.A. (author)This paper explores the basis on which reliable screening of distillation sequences for energy-efficient separation of zeotropic multicomponent mixtures can be carried out. A case study for the separation of natural gas liquids is used to demonstrate the approach. To solve this generic problem, a screening algorithm has been developed using...journal article 2023

Vaquerizo, L. (author), Kiss, A.A. (author)The hydrogenation of CO<sub>2</sub> to methanol is a technology that converts a greenhouse gas into a valuable chemical compound that efficiently stores energy. Several alternatives to perform this process have been proposed, but they are either not thermally self-sufficient and depend on using external fuel, or the power usage per ton of...journal article 2023

Gao, Q. (author), Yang, Haoyu (author), Shanbhag, S.M. (author), Schweidtmann, A.M. (author)Process design is a creative task that is currently performed manually by engineers. Artificial intelligence provides new potential to facilitate process design. Specifically, reinforcement learning (RL) has shown some success in automating process design by integrating data-driven models that learn to build process flowsheets with process...book chapter 2023

(author), Lindeboom, R.E.F. (author), Weissbrodt, D.G. (author)Purple phototrophic bacteria (PPB) show an underexplored potential for resource recovery from wastewater. Raceway reactors offer a more affordable full-scale solution on wastewater and enable useful additional aerobic processes. Current mathematical models of PPB systems provide useful mechanistic insights, but do not represent the full...journal article 2023

van Wijk, Christine (author)Technological developments in the field of digitalisation, automation and sustainability are moving fast in road transport. Without innovative developments in the railway sector, the competitive position of the sector will deteriorate. For this reason, the rail sector must innovate at a faster pace to remain competitive. Also, it is expected...master thesis 2022

Srikrishna, Pranathi (author)This thesis focuses on designing a process for balancing and prioritizing the digital innovation project portfolio of a rental equipment company. The company operates in a traditional industry in which themes like digital transformation and digitalization are new emerging themes that are yet to be accepted by the industry. Therefore, in order to...master thesis 2022

Patraşcu, Iulian (author), Bîldea, Costin Sorin (author), Kiss, A.A. (author)Among other fuel additives — such as MTBE, ETBE, or TAME — 2-methoxy-2-methyl heptane (MMH) can increase the fuel octane number and reduce the CO emission. MMH can be obtained through the exothermal etherification of 2-methyl-1-heptene and methanol. Lately, many researchers have developed more and more efficient processes considering the...journal article 2022

Rokhayati, Erna (author), Kiss, A.A. (author)Ammonia plays critical role as the second most produced chemical commodity with around 80% used in producing nitrogen-based fertilizer. Considering the decline of reserves of fossil-based feedstocks it is imperative to shift towards greener alternatives. However, such green ammonia processes are far from being economically viable. This makes...journal article 2022
