Calcium hydroxide is promising for thermal energy storage due to its low cost and high density. Nevertheless, the powdered material cohesive has conductivity which a major challenge operation of moving bed reactors. One approach facilitate movement reaction stabilisation particles through coating Ca(OH)2 granules with Al2O3 particles. In this work, newly designed reactor concept was specificall...

The hydrodynamic studies of fluidized bed reactor has been reported in terms of pressure drop, minimum fluidization velocity and bed volume expansion to contribute to the optimization of the CNTs production parameters in fluidized bed reactors. Minimum fluidization velocity and pressure drop, as the most important parameters, were taken into account for the investigation of the hydrodynamic beh...

A mathematical model for a hybrid anaerobic reactor (HAR), which uses self-immobilized anaerobic bacterial granules under completely fluidized condition, has been developed. Stoichiometry of glucose fermentation into methane has been considered in this model. The model includes: (1) a biofilm model which describes substrate conversion kinetics within a single granule; (2) a bed fluidization mod...

In the current study a series of pyrolysis and CO2 gasification experiments were conducted on a bed of kraft black char under a perpendicular impinging jet. The experiments demonstrated that the char bed carbon gasification rates are externally mass transfer limited. The mass transfer is further decreased by a net molar out-flow caused by the conversion of one mole of reactant CO2 to two moles ...
