The application of CaO-based sorbents to remove carbon dioxide is based on a reversible reaction between CaO and CO 2 . However, multiple carbonation/calcination cycles lead to a rapid reduction in the sorption capacity of natural CaO, and therefore efforts are made to reduce this disadvantage by doping, regenerating, or producing synthetic CaO with stable sorption properties. In this review, the synthesis methods used to obtain CaO-based sorbents were collected, and the latest research on improving their sorption properties was presented. The most commonly used models to describe the CO 2 sorption kinetics on CaO-based sorbents were also introduced. The methods of sorbent regeneration and their effectiveness were summarized. In the last part of this review, the current state of advancement of work on the larger scale, possible problems, and opportunities during scale-up of the calcium looping process were presented. Concluding (i) the presented methods of adsorbent synthesis allow for the production of doped CaO adsorbents on a laboratory scale, characterized by high CO 2 capture efficiency and good cyclic stability, (ii) the most commonly used in practice models describing CO 2 chemisorption are empirical models and the shrinking core model, (iii) the use of sorbent regeneration allows for a significant improvement in sorption capacity, (iv) the scale-up of both the production of new CaO adsorbents and the CO 2 capture technology with their use requires further development","PeriodicalId":55267,"journal":{"name":"Chemical and Process Engineering-Inzynieria Chemiczna I Procesowa","volume":"234 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135679899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pre-treatment proved to have a significant impact on the drying rate, including the time required to reach moisture content of 10%, essential to start further treatment of biomass for power industry purposes. It was found that debarked samples of robinia lost water more quickly than the crushed ones.

Many different methods of calcium carbonate production and their effect on the various characteristics of the product have been presented and discussed. One of the most important, from the point of view of practical applications, is the morphology and size of the produced particles as well as their agglomerates and size distribution. The size of the obtained CaCO 3 particles and their agglomerates can vary from nanometers to micrometers. It depends on many factors but the most important are the conditions calcium carbonate precipitation and then stored. The experimental research was strongly aided by theoretical considerations on the correct description of the process of calcium carbonate precipitation. More than once, the correct modelling of a specific process contributed to the explanation of the phenomena observed during the experiment (i.e. formation of polyforms, intermediate products, etc.). Moreover, different methods and approaches to the accurate description of crystallization processes as well as main CFD problems has been widely reviewed. It can be used as a basic material to formulation and implementation of new, accurate models describing not only multiphase crystallization processes but also any processes taking place in different chemical reactors.","PeriodicalId":55267,"journal":{"name":"Chemical and Process Engineering-Inzynieria Chemiczna I Procesowa","volume":"258 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135678734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Feasibility of small-scale wave-type agitated single-use bioreactors for gentle agitation underlies applicability of such systems for scaling-up of fragile biomass of animal cells. The basic aim of the study was to compare the results of non-adherent HL-60 cell propagation performed referentially as the batch culture in typical static (i.e. non-agitated) disposable culture flasks (50 cm3 of culture medium) and in ReadyToProcess WAVETM25 bioreactor system (GE Healthcare) equipped with disposable culture bag (300 cm3 of culture medium) subjected to continuous wave-type agitation. The density and viability of HL-60 cells were significantly higher for the bioprocess subjected to wave-type agitation, than in the reference static culture. The values of the specific rate of glucose consumption per cell (rglc/cell) exhibited by HL-60 cells maintained in the system with continuous wave-type agitation was significantly lower (i.e. up to more than 42%) than the values noted for the static culture, for exactly the same time-points of two compared cultures. The results of the studies undoubtedly and comprehensively confirmed the applicability of the studied disposable bioreactor with wave-induced agitation as the right platform for proceeding the propagation of nonadherent HL-60 cells and for providing the culture conditions required by HL-60 cells for sustainable metabolism.","PeriodicalId":55267,"journal":{"name":"Chemical and Process Engineering-Inzynieria Chemiczna I Procesowa","volume":"40 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68947041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This phenomenon, so-called wall slip, often takes place in concentrated suspensions and solutions of linear polymers and introduces experimental errors to measurement results. There are methods of correction of these errors in the case of capillary and coaxial cylinders measuring systems. In the cone and plate system the correction seems to be more difficult because the width of the gap between cone and plate changes along the radius and thus the influence of the wall slip on the shear stress varies along the radius in an unpredictable and complicated manner. This dependency of the shear stress on the distance from the axis underlies the presented method of correction of experimental results obtained in the cone and plate system. The method requires several series of measurements of shear stress vs. shear rate performed using one measuring set, at various degrees of filling the gap.","PeriodicalId":55267,"journal":{"name":"Chemical and Process Engineering-Inzynieria Chemiczna I Procesowa","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68947048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
