“…As the coke is produced, the degradation of the catalyst is accelerated until the catalyst is deactivated by coking and continuation of catalyzed reforming becomes impossible. To improve the stability of the Ni-based catalyst and its resistance to coking, many researchers have considered adding another metal to Ni to form a bimetallic structure on the same support, with small amounts of O 2 fed with steam and propane [8][9][10][11][12].…”

“…The use of ceria or mixed oxides containing ceria as support for reforming catalysts has been reported to prevent metal sintering, due to strong metal-support interactions (SMSI). In addition, ceria enhances the resistance towards carbon deposition due to the oxygen storage capabilities associated with the change of cerium valence states (Ce 4þ and Ce 3þ ) [17,24,25,31].…”

“…In the conversion of C 3 C 4 alkanes, the stability of the catalyst to form CDs is important. Catalysts based on Rh, Ru, Pt, and other noble metals have high activity and stability in the vapor conversion of APG [1,2]. However, they are expensive, and therefore, nickel catalysts are the most widely used.…”

Steam reforming of n-butane has been studied in a membrane reactor at temperatures of 673-823 K, feed hourly space velocities of 1800 and 3600 h-1 , and steam/butane ratios of 3, 5 and 7. Under selected conditions, the steam conversion is accompanied by the formation of carbon deposits, whose yield decreases with increasing steam excess. However, with an increase in steam excess, its negative effect on H 2 recovery through the membrane increases. Comparative experiments with the "non-membrane" reaction at a constant steam/butane ratio equal to 5 have shown that butane conversion to the target products increases in the membrane reactor and the rate of carbon deposits formation decreases. When replacing the sweep gas by the vacuum conditions in the permeate side, there is a further decrease in the rate of carbon deposits formation and an increase in the butane conversion in the main reaction. With an increase in feed hourly space velocity from 1800 to 3600 h-1 , the rate of carbon deposits formation and its dependence on temperature increase. At an hourly space velocity of 1800 h-1 , the rate of formation of carbon deposits is two to three times lower and varies slightly with temperature. Under these conditions, the butane conversion is close to 100%; about 80% of H 2 formed is recovered from the reaction mixture, and at vacuum conditions in the permeate side, the H 2 recovery is 95%.
