Synthesis and Characterization of Ru/Al2O3 Nanocatalyst for Ammonia Synthesis
Ru/Al2O3 catalysts were prepared by conventional incipient wetness impregnation as well as colloid deposition of RuCl3 precursor via in situ reduction with ethylene glycol (polyol) method on alumina support. The samples were characterized by TEM, XRD and TPR techniques. The catalytic performance tests were carried out in a fixed-bed micro-reactor under diffe...
متن کاملControl structure design for the ammonia synthesis process
This paper discusses the application of the plantwide control design procedure of Skogestad [Skogestad, S. (2004a). Control structure design for complete chemical plants. Computers and Chemical Engineering, 28, 219–234] to the ammonia synthesis process. Threemodes of operation are considered: (I) given feed rate, (IIa) maximum throughput, and (IIb) “optimized” throughput. Two control structures...
متن کاملoff-gas treatment of ammonia using a diffused air stripper: a kinetic study
conclusions the ammonia degassing is a simple and suitable technology for ammonia removal at high concentration. undesirable removal efficiency (17%, 35.5% and 31%) can be occurred in suitable ph 11 in the presence of lower ammonia concentrations (50, 100 and 200 mg/l). results according to obtained results, the maximum removal efficiencies were determined 17%, 35.5%, 31%, 66%, and 85.5%, for 5...
متن کاملPerformance evaluation and availability analysis of ammonia synthesis unit in a fertilizer plant
This paper discusses the performance evaluation and availability analysis of ammonia synthesis unit of a fertilizer plant. The fertilizer plant is a complex and repairable engineering system comprises of various units viz. shell gasification and carbon recovery, desulphurization, co-shift conversion, decarbonation, nitrogen wash and ammonia synthesis etc. One of the most important functionaries...
