Experimental Validation of CFD Hydrodynamic Models for Catalytic Fast Pyrolysis (CFP)
Researchers at KiOR LLC working with CPFD Software staff use Barracuda Virtual Reactor to develop a Catalytic Fast Pyrolysis (CFP) technology that emulates the FCC process.
CFD Studies on Biomass Gasification in a Pilot-Scale Dual Fluidized-Bed System
A model using the MP-PIC method was developed to simulate a pilot-scale dual fluidized-bed biomass gasification system and was validated by experimental results; it was then used to investigate the impact of various changes on the producer gas composition.
CPFD Modeling and Experimental Validation of Gas–Solid Flow in a Down Flow Reactor
In this paper, a hybrid model of a gas-solid fluidized bed unit is developed using Barracuda Virtual Reactor and then is validated by experimental data.
Particle Attrition: Mechanisms and Methods to Determine Attrition Indices
Particle attrition can be a major issue in using catalyst particles in fluidized beds and circulating fluidized beds. Particles tend to break down via two mechanisms – abrasion and fragmentation.
