20.500.12556/RUL-160436 Metanacija ogljikovega monoksida ob prisotnosti nikljevega katalizatorja v šaržnem reaktorju z goščo Carbon monoxide methanation in the presence of a nickel catalyst in a batch reactor Iz ogljikovega monoksida in vodika sem poskušal sintetizirati metan. Poskusi so se izvajali pri povišani temperaturi in povišanem tlaku ob prisotnosti Raney-jevega niklja, katalizatorja, dispergiranega v vodni fazi in sicer v šaržnem reaktorju. Poleg reakcij, kjer je bil vodik dodan že v začetno zmes, so bili med drugim izvedeni poskusi, ki so se za vir vodika zanašali na reakcijo vodnega plina, torej v reaktorju ni bilo dodanega vodika. Plinasti produkti so bili analizirani s pomočjo plinske kromatografije. Pri določanju sestave vzorca je bila poleg deleža in količine metana opazovana tudi prisotnost drugih plinov. Najvišji dosežen izkoristek je znašal 64,1 %, vsebnost ogljikovih oksidov pa je bila tudi pri tej reakciji relativno visoka; sintetizirani produkti opravljenih reakcij torej ne bi bili primerni za komercialno uporabo. Methane was attempted to be synthesised from carbon monoxide and hydrogen. The experiments were carried out at elevated temperature and pressure in a batch reactor. The reactions were conducted in the presence of a Raney nickel catalyst, dispersed in the aqueous phase. In addition to the reactions where hydrogen was initially added to the mixture, experiments relying on the water-gas shift reaction as a source of hydrogen were also performed. The gaseous products were analysed using gas chromatography. In determining the composition of the sample, not only the percentage and quantity of methane was observed, the presence of other gases was also monitored. The highest achieved yield was 64,1% while the content of carbon oxides was still relatively high; products synthesised with this setup would therefore not be suitable for commercial use. metanacija ogljikov monoksid Raney-jev nikelj reakcija vodnega plina methanation carbon monoxide Raney nickel water-gas shift reaction true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2024-08-28 13:55:00 2024-08-28 13:55:08 2024-09-06 12:16:18 0000-00-00 00:00:00 2024 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 24146 206639875 Zgonc_Urban_-_Metanacija_ogljikovega_monoksida_ob_prisotnosti_nikljevega_katalizatorja_v_sarznem.pdf Zgonc_Urban_-_Metanacija_ogljikovega_monoksida_ob_prisotnosti_nikljevega_katalizatorja_v_sarznem.pdf 1 004B1DBFB86D65F052BA8294B19DC55A 16487f1af8bd89e1d7b0e3806eeff79c1b8a30fbc1690f2e9fd1dbc8accd9c1d 262d85b4-6534-11ef-8f74-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=189126 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
