“…It is generally accepted that this oxidation occurs both heterogeneously (on the surface of the catalyst) and homogenously (in the gas phase in the intra particle spaces or pores, and in the bulk gas phase); however, to what extent each of these reactions is significant is not entirely clear. Early workers [45][46][47][48][49] carried out studies towards the development of a global carbon monoxide burnout rate in the gaseous form, in the temperature range 770-2400 K using a variety of fuels such as propane and methane. Although their experiments are not directly on FCC regeneration, they still present a good understanding of the homogenous carbon monoxide oxidation reaction.…”

Heavy petroleum industries, including the Fluid Catalytic Cracking (FCC) unit, are among some of the biggest contributors to global greenhouse gas (GHG) emissions. The FCC unit’s regenerator is where these emissions originate mostly, meaning the operation of FCC regenerators has come under scrutiny in recent years due to the global mitigation efforts against climate change, affecting both current operations and the future of the FCC unit. As a result, it is more important than ever to develop models that are accurate and reliable at predicting emissions of various greenhouse gases to keep up with new reporting guidelines that will help optimise the unit for increased coke conversion and lower operating costs. Part 1 of this paper was dedicated to reviewing the riser section of the FCC unit. Part 2 reviews traditional modelling methodologies used in modelling and simulating the FCC regenerator. Hydrodynamics and kinetics of the regenerator are discussed in terms of experimental data and modelling. Modelling of constitutive parts that are important to the FCC unit, such as gas–solid cyclones and catalyst transport lines, are also considered. This review then identifies areas where the current generation of models of the regenerator can be improved for the future. Parts 1 and 2 are such that a comprehensive review of the literature on modelling the FCC unit is presented, showing the guidance and framework followed in building models for the unit.

“…Initial experiments by Dr. Bruce Raby of UTI confi.rm that the Q-30C system can easily resolve a gas mixture similar to that expected during coal gasification (5.85% C0 2 , 3.94% CO, 7.91% H 2 , 2.06% CH 4 ). Multiple least squares analysis can be used to calculate species concentrations (CH 4 , CO, co 2 , H 2 , o 2 , N 2 , H 2 0) with an expected accuracy of 2-5% (Damoth and Montgomery, 1972;Singh, 1970;Fuchs et al, 1974). Use of a Faraday cup, rather than the electron multiplier, will enhance response linearity.…”

“…Hydrogen measurements are feasible (even with an ion pump) for [H 2 ] < 15-25%. Distinguishing CO from N 2 is achievable for CO/N 2 > 0.01 (Damoth and Montgomery, 1972;Singh, 1970).…”
