Abstract Hydrocarbon reforming is emerging as the primary pathway to produce hydrogen in an economy that is shifting its dependence over to hydrogen [Aasberg-Petersen et al., 2001; Sarmiento et al., 2007; Rostrup-Nielsen, 2009, Alenazey et al, 2009]. Current catalytic research is concentrating on cracking methane and carbon dioxide in order to produce hydrogen and syngases (which are mixtures of hydrogen and carbon monoxide).
The active use of methane and carbon dioxide is also helpful because these gases are not environmentally friendly and their conversion to feedstock will enable better environmental regulation. During the conversion process, one of the major problems is catalyst deactivation resulting from coke deposition. The deposition of coke produces poor catalyst selectivity, activity and longevity. The aim of this project is to investigate the effects of forced periodic cycling between a carbon-gasifying agent (such as carbon dioxide) and methane dry reforming in order to increase the yield of syngases and to improve catalyst longevity. This study will also bolster innovation by developing the traditional Ni-CO catalyst using cerium oxide as a promoter. This approach has been shown to favour synthesis gas formation along with resistance to coking in various studies on the matter. The achievement of these goals may lead to significant improvements in hydrocarbon reforming in context of catalyst deactivation and would also lead to an improved catalytic reforming system. These improvements would in turn provide substantial economic and environmental benefits through a positive reduction in greenhouse gases. 1. Literature Review 1.1. ...
