20.500.12556/DKUM-66944 Production of biogas by CSF technology Proizvodnja biogasa tehnologijom natkritičnih fluida Hydrogen is expected to become an important fuel in the long-term since in combination with fuel cells it offers the opportunity of an intrinsically clean energy supply. By application of supercritical water gasification (SCWG) concept, sustainable hydrogen can be produced from biomass and waste. The paper offers an overview of some recently published papers dealing with SCWG of model compounds and a summary of the investigations on SCWG of real agricultural and food processing wastes. In the frame of our work an intense research was performed to support analyses of SCWG of glycerol and was supported by the investigation of phase equilibrium for the systems gas/water and gas mixtures/water. When glycerol/water solutions were directly injected in the reactor operating at supercritical conditions, gases with high C2+ were obtained by the reforming in supercritical water unit. To reduce the hydrocarbon concentrations and to obtain a syngas with higher CO/CO2 ratios from a mixture of gases (H2, CO, CO2 and CH4), catalytic reactions at high pressure and temperature were introduced reflecting in an increase of the content of H2 and CO. Solubility measurements were conducted for the binary systems of gas and water at elevated pressures and temperatures. Očekuje se da vodonik postane važno gorivo na duži rok, jer u kombinaciji sa gorivnim ćelijama nudi mogućnost snabdevanja suštinski čistom energijom. Primenom koncenpcije gasifikacije natkritičnom vodom (SCVG), održivi vodonik može da se proizvede iz biomase i otpada. U ovom radu dat je pregled nekih nedavno objavlјenih istraživanja koja su se bavila SCVG model jedinjenja i stvarnih polјoprivrednih i prehrambenih otpada. U okviru ovog rada, intenzivno istraživanje je sprovedeno radi analize SCVG glicerola, a podržan je istraćivanjem fazne ravnoteže za sisteme gas/voda i gasne smeše/voda. Kada su rastvori glicerola u vodi ubrizgani direktno u reaktor koji radi na natkritičnim uslovima, dobijeni su gasovi sa visokim C2+ reformingom u jedinici sa natkritičnom vodom. Da bi se smanjila koncentracija uglјovodonika i dobije singas sa većim odnosom CO/CO2 iz smeše gasova (H2, CO, CO2 i CH4), korišćene su katalitičke reakcije na visokom pritisku i temperaturi, što povećava sadržaj H2 i CO. Sprovedena su određivanja rastvorlјivosti za binarne sisteme gas/vode na povišenim pritiscima i temperaturama. biogas SCF technology biotechnology bioplin SCF tehnologija biotehnologija true false true Angleški jezik Srbski jezik Znanstveno delo 2017-07-19 11:26:12 2017-07-19 11:27:24 2022-08-01 13:22:20 2019-07-11 16:04:25 2016 0 0 str. 333-342 št. 4 Letn. 22 2016 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1451-9372 66.02 9527830 19574294 10.2298/CICEQ160406021K 1451-9372 URN:SI:UM:DK:COMGPPBQ Chemical_Industry_and_Chemical_Engineering_Quarterly_2016_Knez-Hrncic,_Skerget,_Knez_Production_of_biogas_by_SCF_technology.pdf Chemical_Industry_and_Chemical_Engineering_Quarterly_2016_Knez-Hrncic,_Skerget,_Knez_Production_of_biogas_by_SCF_technology.pdf 1 C336C6C89804480F849BCF875ED12690 9b10ceedaa7e4ac87cb46ecc5a301131e947638bd3a3cfc0e8055c5f2a8c66de 6e9b75d9-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/e00ee430-6bb5-41d2-8de7-2ca0df996b1b https://dk.um.si/Dokument.php?lang=slv&id=114367 http://www.doiserbia.nb.rs/Article.aspx?ID=1451-93721600021K 1 https://dk.um.si/Dokument.php?lang=slv&id=114366 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
