Hydrogen production by catalytic cracking of methane over nickel gauze under periodic reactor operation
The catalytic cracking of methane over nickel gauze is proposed as an attractive alternative for the production of CO-free hydrogen. The catalyst deactivates due to intensive coke deposition. Therefore, the reactor was operated periodically with the reaction followed by the catalyst regeneration by burning of coke in oxidative atmosphere. The optimal reaction performance was found to consist of...
متن کاملEffect of Oxygen and Micro-Cracking on the Flotation of Low Grade Nickel Sulphide Ore
This study investigated the effect of oxygen and micro-cracking on the flotation of low grade nickel sulphide ore. The ore treated contained serpentine minerals which have a history of being difficult to process efficiently. The use of oxygen as a bubbling gas has been noted to be effective because it increases the pulp potential. The desired effect of micro cracking the ore is that the nickel ...
متن کاملOlefin production from catalytic cracking of light fuel oil over different additives
The catalytic cracking of a fuel oil over fluid catalytic cracking (FCC) catalyst has been investigated applying different additives. Catalyst mixtures consisting of a equilibrium FCC catalyst (E-Cat) blended with ZSM-5, MCM-41 and Mordenite additives were examined at the additive levels of 25 wt.%. The catalytic performance of the matrix was studied in a fixed bed micro-activity test unit (MAT...
متن کاملVacuum residue upgrading by pyrolysis-catalysis procedure over mesoporous ZSM-5 zeolite
A systematic study of two-staged upgrading process of vacuum residue for light fuel production has been carried out in a semi-batch binary reactor apparatus over Y, ZSM-5 and alkaline treated ZSM-5 zeolites. Prepared catalyst samples were characterized with XRD and BET. Density and Viscosity physical properties parameters estimation, as well as GC/SIMDIS analyses were conducted on liquid produc...
