This work shows a statistical model that predicts the quantity of methanol produced through a batch conversion process employing copper-exchanged mordenite in accordance with a full factorial experimental design. Synthesis was performed through solid-state ion exchange from Cu(acac)2 and NH4-Mordenite, obtaining weight percentages (%Cu) of 1%, 3%, and 5%, which was followed by activation through calcination at a range of temperatures (Tcal) between 300-500 °C, as well as a reaction with methane under 2-10 bar pressure (P) in static conditions employing a batch reactor. The quantities of MeOH produced, and their yields were determined through a gas chromatography and mass spectrometry analysis of the reaction samples. Finally, the role and contribution of each of the variables considered in the conversion process were analyzed. By using a nonlinear model, a quadratic dependence with %Cu and P in the studied range of the variables was found, as well as a linear dependence with Tcal. Finally, for this experiment, the highest yields (μmol/g) were obtained with the following conditions: %Cu = 3 %, P = 6 bar, and Tcal = 400 °C. 2021 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64379876006 https://www.redalyc.org/journal/643/64379876006/ https://www.redalyc.org/journal/643/64379876006/html/ https://www.redalyc.org/journal/643/64379876006/64379876006.epub https://www.redalyc.org/journal/643/64379876006/movil 10.15446/ing.investig.v41n3.87537 en http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.3 Vol.41 |
