A fluidized bed reactor that is operating in the bubbling regime has been developed for the conversion of bio-oils to syngas.The reactor consists of a 7.6 cm I.D. (or internal diameter) bed, with an expanded freeboard. The volume of the reactor can be adjusted to vary the gas residence time. This reactor has been used to carry out either thermal or catalytic cracking for reforming bio-oils.A ga...

The paper outlines the concept of process intensification and integration, with a particular focus on sorption-enhanced, solid-catalyzed chemical processes. An alternative attractive solution to system parallel fixed-bed apparatuses is evaluated, which utilizes solids’ circulation in dual fluidized-bed reactor–regenerator system. This allows for continuous mode operation greatly simplifies cont...

Abstract Considering the different particle sizes in circulating fluidized bed boiler furnace, binary-component method is used to analyze flow characteristics furnace. The dynamics principle solve gas-solid two-phase mass equation, momentum equation and turbulence using two-fluid model. model uses more mature design drawings, reproduces of particles obtains shape lower bubbling fast upper bed, ...

Abstract The effect of the solid–wall boundary condition on the segregation behavior of a sand ternary mixture differing in size but having the same proportion has been investigated in a gas–solid bubbling fluidized bed. A multi-fluid computational fluid dynamics model incorporating the kinetic theory of granular flow has been used. The mass fraction profiles of the different-sized partic...
