“…The biomethane can be used as advanced biofuel or injected directly into the gas grid. At present, the most used technologies for this purpose are water washing, chemical or physical absorption, andsorption dominantly in pressure swing configuration [60] or innovative membrane permeation [61]. A commercial hollow polyimide membrane is often applied for CO 2 removal from biogas for further effective reuse [62].…”

The world is moving towards decarbonization policies in the energy and industrial sectors to bring down carbon dioxide release and reach net zero emissions. Technologies to capture CO2 and use it as a feedstock to produce CO2-based chemicals and biofuels via chemical or biochemical conversion pathways can potentially reduce the amount of CO2 released. The paper serves the innovative scientific knowledge for CO2 transformation via a biochemical pathway to microalgal biomass with its subsequent treatment to biofuels and bioproducts assuming milder climatic conditions (Central or Eastern Europe, Visegrad countries or climatically related world regions). The recent trends were critically reviewed for microalgal biorefinery to reach the sustainability of microalgal-based chemicals with added value, digestion, hydrothermal liquefaction, pyrolysis, and gasification of microalgal residues. Knowledge-based chemical process engineering analysis, systematic data synthesis, and critical technical evaluation of available life cycle assessment studies evaluated the sustainability of microalgal biorefinery pathways. The research showed that biological CO2 fixation using water, seawater or wastewater to produce third-generation biomass is a promising alternative for bioethanol production via pretreatment, enzymatic hydrolysis, digestion, and distillation, and can be realized on a large scale in an economically viable and environmentally sound manner. Its best economically promising and sustainable pathway is perceived in producing microalgal-based nutraceuticals, bioactive medical products, and food products such as proteins, pigments, and vitamins. Machine learning methods for data mining, process control, process optimization, and geometrical configuration of reactors and bioreactors are the crucial research needs and challenges to implementing microalgal biorefinery in an operational environment.

“…Te material, momentum, and energy balances must be considered to model a rigorous PSA process. Several model assumptions were used as a foundation of building the model [33]. Tese include (1) Te bulk gas phase is considered an ideal gas, PV � nRT (2) Te bed properties, such as porosity and bulk solid density, is assumed to be uniform in both axial and radial coordinates (3) No reaction was involved between the adsorbed gas and solid adsorbent (4) Te radial temperature and concentration gradients are insignifcant.…”

“…Te adsorption of gas molecules onto the surfaces of the solid adsorbent is governed by a mathematical expression that measures the extent of the adsorption in an adsorbate/adsorbent system, which is known as equilibrium adsorption isotherm when it is measured at varying pressure with a constant temperature [33]. Many adsorption isotherms have been applied to describe the equilibrium relationship between the gas and adsorbed phases as a function of pressure; among others are Langmuir, Freundlich, Langmuir-Freundlich, etc.…”

“…Te nonisothermal process of PSA is contributed by the heat adsorbed and released throughout the cycle, which is governed by various aspects, including heat of adsorption, heat convection and conduction, and thermal accumulation [33]. A complete energy balance equations require three control volumes to be defned, which are gas-phase, solid-phase, and wall.…”

Oxygen, an odorless and colorless gas constituent of the atmosphere, is a vital gas component for the Earth, as it makes up 21% of the composition of the air we breathe. Apart from the importance of oxygen for human breathing, its highly pure form is demanding for industrial applications. As such, several technologies have been established to increase the oxygen purity from 21% to somewhat higher than 95%. One of the competitive technologies for producing this high-purity oxygen from the air is through pressure swing adsorption (PSA), which has the advantages of low cost and energy while being highly efficient. Also, PSA is a simple and flexible system due to its ability to start up and shut down more rapidly since its operation occurs at ambient temperature, which is enabled through the use of adsorbents to bind and separate the air molecules. The enhancement of the PSA’s performances was reported through the modification of PSA step cycles and material (zeolite) tailoring. A simplified complete set of a mathematical model is included for modelling the PSA system, aiming to ease the experimental burden of the process design and optimization of an infinite modification of PSA step cycles. Finally, some technological importance of oxygen production via PSA, particularly for onboard oxygen generation system and oxy-enriched incineration of municipal solid waste, was discussed. Continuous development of PSA will make significant contributions to a wide range of chemical industries in the near future, be it for oxygen production or other gas separation applications.
