Aspen Plus Simulation of Biomass Gasification with known

The combustion zone is a circulating fluidized bed reactor where the fluidizing gas is air. In the combustion zone, inert bed materials, such as olivine particles or quartz sand, are heated by burning of char. The heated bed material is then circulated to the gasification reactor.

Furthermore, although a fluidized bed reactor is generally utilized in conventional catalytic oxidation processes, we believed that it would be beneficial to employ a fixed bed reactor, in order to achieve a higher conversion. To accom-plish this, we allowed high activity catalysts to react at low temperatures during the last half

Process Simulation and Modeling of Fluidized Catalytic

The simulation of fluidized catalytic cracking (FCC) process was performed using Aspen HYSYS. The effect of crude flow rate on naphtha flow, coke yield, and catalyst to oil ratio in FCC were simulated. The interaction effects of riser height, inlet crude flow rate and operating temperature on naphtha mass flow, catalyst to oil ratio, and coke yield were studied by Box-Behnken design.

A Practical Model for a Dense- Bed Countercurrent FCC

A regenerator is an indispensable part of a FCC unit, acting as a fluidized-bed reactor to burn the coke deposited in the spent catalyst and recover its cracking activity. An ideal FCC regenerator requires very low levels of carbon content in regenerated catalyst (CCR) (0.05~0.1 wt%) with minimized air consumption and maximized coke

Abstract. In this study, we developed a three-stage catalyst-adsorbent reactor for the catalytic hydrolysis of CF 4.Each stage is composed of a catalyst bed followed by an adsorbent bed using Ca(OH) 2 to remove HF. The three stages are connected in series to enhance the hydrolysis of CF 4 and eliminate a scrubber to dissolve HF in water at the same time. . With a 10 wt-% Ce/Al 2 O 3 catalyst
