An effective approach to enhance catalytic activity in Propane oxidative dehydrogenation by surface grafted single site VOx moieties over catalytic supports
King Abdullah University of science and technology, Kingdom of Saudi Arabia
The oxidative dehydrogenation (ODH) of propane isregarded as a promising and advantageous strategy for theindustrial scale production of propylene which is highly demanded by the chemical industry. ODH represents a viable strategy to complementcurrently applied technologies such as cracking and non-oxidative hydrogenation. Exothermicity of ODH allows the process to operate under a thermodynamically favorableregime, whereas the presence of oxygen prevents coking at thecatalyst surface. Though this process is economically favorable, it suffers a major disadvantages of low selectivity of propylene due to itʼs over oxidation to COx. This problem can be solve by correlating structure and activity of catalytic species and deep understanding of mechanism of structural features in reaction. Surface grafting offers a unique feature to understand better structural catalytic activity of relationship and helps to enhance catalytic activity in propane ODH. In current study, with the help of surface grafting we prepared highly dispersed vanadiumspecies over different supports. These highly dispersed vanadium species were characterized by several analytical techniques. It has been observed that these highly dispersed species play a crucial role in order toachieve higher catalytic activity and selectivity towards propylene.
