Sorption enhanced synthesis has been previously shown to improve carbon dioxide hydrogenation methanol by mitigating the thermodynamic limitations. This work investigates efficiency of via sorption focusing on determining optimal process parameters. The study is based upon a fully dynamic experimentally validated model which extended account for adsorbent regeneration, downstream product separa...

Sodium borohydride (NaBH4) hydrogen storage systems offer many advantages for hydrogen storage applications. The physical processes inside a NaBH4 packed bed reactor involve multi-component and multi-phase flow and multi-mode heat and mass transfer. These processes are also coupled with reaction kinetics. To guide reactor design and optimization, a reactor model involving all of these processes...

This paper presents a review of advances that have taken place in the mathematical programming approach to process design and synthesis. A review is first presented on the algorithms that are available for solving MINLP problems, and its most recent variant, Generalized Disjunctive Programming models. The formulation of superstructures, models and solution strategies is also discussed for the e...

focus of fundamental and applied materials research since the first preparation of macroscopic C60 quantities by Krätschmer et al. in 1990 [1]. The ability to encage atoms and small molecules opened the door to new structures which are highly reactive under standard conditions. Up to now low production yields and a time consuming multi stage separation hampered the search for applications of en...

Splitting CO2 with a thermochemical redox cycle utilizes the entire solar spectrum and provides a favorable path to the synthesis of solar fuels at high rates and efficiencies. However, the temperature/pressure swing commonly applied between reduction and oxidation steps incurs irreversible energy losses and severe material stresses. Here, we experimentally demonstrate for the first time the si...

Catalytic membrane reactors are multifunctional reactors, which provide improved performance over conventional reactors. These are used mainly for conducting hydrogenation/ dehydrogenation reactions, and synthesis of oxyorganic compounds by using inorganic membranes. In this paper, comprehensive model has been developed for a tubular membrane reactor, which is applicable to Pd or Pd alloys memb...

The paper presents a systematic approach for the extraction, interpretation and exploitation of design knowledge in process synthesis. Knowledge is developed in the course of superstructure optimisation. Semantic models (ontologies) and analytical tools are combined to simplify the superstructures and interpret solutions. In the course of the search the method translates intermediate solutions ...

This paper introduces a new framework to support synthesis of complex engineering problems and which combines stochastic serach optimisation with ontological knowledge modelling. The framework uses Tabu search to generate new solutions and introduces the mechanism of digital certificate to translate between structural information of solutions and semantics of ontology. The solutions are respect...
