Abstract:

An in-situ study of carbon deposition parameters by the method of chemical vapor deposition (CVD) from methane is used in order to estimate the time of the deactivation catalyst (Fe/Mo catalyst supported on alumina (Al2O3)). The deposition process is studied by measuring the weight change of the sample using a microbalance. The effect of the operating parameters, such as temperature, feed concentration, and catalyst composition, on the deposition rate and morphology of the deposits is investigated. Based on the initial weight of the catalyst, the relative weight gain of the sample due to carbon deposition on the catalyst is higher than 300% in a few minutes of the deposition process but the deposition rate reduces in more than 100 min. The carbon material characterized with Scanning Electron Microscopy (SEM) and Raman Spectroscopy and it is found to consist of carbon nanostructures.
