A Gas-Phase Model for the Pt-Catalyzed Coupling of Methane and Ammonia**
The activation of methane has been referred to as one of the central challenges in contemporary chemical research.[1] In addition to various academic aspects, methane activation is of eminent industrial importance. One economically attractive process is the coupling of ammonia and methane according to reaction (1) to afford hydrogen cyanide, a valuable feedstock for chemical synthesis. Reaction...
متن کاملMiniplant-Scale Analysis of Oxidative Coupling of Methane Process
For more than three decades, Oxidative Coupling of Methane (OCM) process has been comprehensively investigated as an attractive alternative for the commercially available ethylene production technologies such as ethane and naphtha cracking. Developing a suitable catalyst and proper reactor feeding policy, reviewing and deploying the efficient methods in the separation and purification of the un...
متن کاملAPPLICATION OF ADAPTIVE NEURO FUZZY INFERENCE SYSTEM TO MODELING OXIDATIVE COUPLING OF METHANE REACTION AT ELEVATED PRESSURE
The oxidative coupling of methane (OCM) performance over Na-W-Mn/SiO2 at elevated pressures has been simulated by adaptive neuro fuzzy inference system (ANFIS) using reaction data gathered in an isothermal fixed bed microreactor. In the designed neuro fuzzy models, three important parameters such as methane to oxygen ratio, gas hourly space velocity (GHSV), and reaction temperature were conside...
متن کاملOptimization of Two-Dimensional Flows with Homogeneous and Heterogeneously Catalyzed Gas-Phase Reactions
Chemically reacting gaseous flows in catalytic monoliths are numerically investigated to mathematically optimize product yields by the variation of operating conditions and catalyst loading. The fluid dynamics of the single monolith channel is modeled by the two-dimensional boundary layer equations (BLEs), a system of parabolic partial differential equations (PDEs) with highly nonlinear boundar...
