“…Details of the most recent version for cases of bubbling fluidized beds have been recently published [1,2] and are not repeated here. As seen, the program is also applicable to bubbling fluidized units operating with partial or complete re-injection into the bed of particles collected at the cyclone system.…”

“…Recent publications have shown how well a new version of a mathematical model and simulation program (CSFB or CSFMB) is capable of reproducing boilers and gasifiers operational conditions working under bubbling fluidized bed [1,2]. That is the product of several improvements introduced during the last 20 years since the first version of the mathematical model and respective simulation program .…”

“…Among other details, their conclusions justify the application of Wen and Chen's relation [44] describing the flux of solid against the height in the freeboard or lean region. Those relations have been used in CSFMB model since its first version [3,4] and more details can also be found elsewhere [1,2] (see, for instance, relations A.30, A.31, and A.32 at ref. [2]).…”

“…The model for that was taken from the work of Pécora [27][28][29]. Of course, the relations concerning to energy and mass balances for the dense and lean regions continue to be valid and similar to the applied before [1][2]. In addition, the relationships used to predict the operation of cyclone system were similarly applied, including computations to provide the heat transfers between the returning leg and surroundings.…”

in Wiley Online Library (wileyonlinelibrary.com)During fluidized bed biomass gasification, complex gas-solid mixing patterns and numerous chemical and physical phenomena make identification of optimal operating conditions challenging. In this work, a parametric experimental campaign was carried out alongside the development of a coupled reactor network model which successfully integrates the individually validated sub-models to predict steady-state reactor performance metrics and outputs. The experiments utilized an integrated gasification system consisting of an externally-heated, bench-scale, 4-in., 5 kWth, fluidized bed steam/air blown gasifier fed with woody biomass equipped with a molecular beam mass spectrometer to directly measure tar species. The operating temperature (750-8508C) and air/fuel equivalence ratio (ER 5 0-0.157) were independently varied to isolate their effects. Elevating temperature is shown to improve the char gasification rate and reduce tar concentrations. Air strongly impacts the composition of tar, accelerating the conversion of lighter polycyclicaromatic hydrocarbons into soot precursors, while also improving the overall carbon conversion.

Petroleum coke gasification: A review

et al. 2013

View full text Add to dashboard Cite

The production of petroleum coke (petcoke) in the refineries is progressively peaking up because of the trend of processing heavy crudes and in turn, a renewed interest in delayed coking process. Therefore, an efficient, economical, and environmentally safe utilisation of petcoke has become imperative in the current petroleum refining scenario. Gasification of petcoke has emerged as one of the attractive options and is gaining increasing attention to convert the petcoke to value‐added products. The process offers the refiners a variety of product slates mainly via synthesis gas route. The products include steam, hydrogen, electricity, chemicals (viz. methanol, ammonia, etc.), liquid fuels via Fischer–Tropsch (F‐T) synthesis and so on. Petcoke has been identified as a potential feedstock for about 15% of the total planned gasification capacity worldwide. In the present communication, the published literature pertaining to petcoke gasification has been extensively analysed and a state‐of‐the‐art review has been written that includes: (1) the importance of petcoke gasification in the present petroleum refining scenario; (2) petcoke gasification reaction mechanism, kinetics, and typical product profile; (3) parametric sensitivity of the operating variables such as temperature and pressure; (4) various gasifiers for petcoke gasification; (5) modelling efforts on different types of gasifiers and (6) future prospects of petcoke gasification. An attempt has been made to get the afore‐mentioned aspects together in a thematic framework so that the information is available at a glance and is expected to be useful as a single point source to the researchers and practicing refiners.
