Water gas shift membrane reactor (WGSMR) enables a promising way of syngas-to-hydrogen conversion with favourable carbon dioxide sequestration capabilities. This paper deals with a numerical approach to the modelling of a water gas shift reaction (WGSR) in a membrane reactor which promotes a reaction process by selectively removing hydrogen from the reaction zone through the membrane, making the reaction equilibrium shifting to the product side. Modelling of the WGSR kinetics was based on Bradford mechanism which was used to develop a code within Mathematica programming language to simulate the chemical reactions. The results were implemented as initial and boundary conditions for the tubular WGSMR model designed with Aspen Plus software to analyze the broader system behaviour. On the basis of selected boundary conditions the designed base casemodel predicts that 89.1% CO conversion can be achieved. Calculations show that more than 70% of carbon monoxide conversion into hydrogen appears along the first 40% of reactor length scale. For isothermal conditions more than two thirds of the heat released by WGSR should be extracted from the first 20% of the reactor length. Sensitivity analysis of the WGSMR was also performed by changing the membranes permeance and surface area"},{"@xml:lang":"sl","#text":"Obravnavan je model membranskega reaktorja za konverzijo CO z vodno paro (WGSMR - Water- Gas Shift Membrane Reactor) v kombinirani plinsko-parni elektrarni z uplinjevalnikom (IGCC - Integrated Gasification Combined Cycle) in zajemom CO2. Z uporabo uplinjanja premoga je prikazana tehnologija pridobivanja sinteznega plina za pogon plinsko-parnih postrojenj. Namen integracije membranskega reaktorja v IGCC postrojenje je pridobivanje H2 iz sinteznega plina z uporabo WGS reakcije. Sintezni plin v večini sestavljajo CO, H2, H2O in CO2, z WGS reakcijo pa lahko CO pretvorimo v H2 in CO2. Proces konverzije CO poteka tako, da sintezni plin vstopa v reaktor na zaporno stran membrane, ki prepušča samo H2. V sinteznem plinu vsebovan H2 in H2, ki nastaja pri konverziji, prehaja na prepustno stran membrane, kjer ga iz reaktorja potiska odnašalni plin (navadno N2)"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-YBIMEDOA","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-YBIMEDOA"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-YBIMEDOA/669cc226-bb8b-44ba-a957-0d460d59e89e/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-YBIMEDOA/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-YBIMEDOA"}}}}
