@article{(Open Science Index):https://publications.waset.org/pdf/4340, title = {Solid Concentration in Circulating Fluidized Bed Reactor for the MTO Process}, author = {Biao Wang and Tao Li and Qi-wen Sun and Wei-yong Ying and Ding-ye Fang}, country = {}, institution = {}, abstract = {Methanol-to-olefins (MTO) coupled with transformation of coal or natural gas to methanol gives an interesting and promising way to produce ethylene and propylene. To investigate solid concentration in gas-solid fluidized bed for methanol-to-olefins process catalyzed by SAPO-34, a cold model experiment system is established in this paper. The system comprises a gas distributor in a 300mm internal diameter and 5000mm height acrylic column, the fiber optic probe system and series of cyclones. The experiments are carried out at ambient conditions and under different superficial gas velocity ranging from 0.3930m/s to 0.7860m/s and different initial bed height ranging from 600mm to 1200mm. The effects of radial distance, axial distance, superficial gas velocity, initial bed height on solid concentration in the bed are discussed. The effects of distributor shape and porosity on solid concentration are also discussed. The time-averaged solid concentration profiles under different conditions are obtained.}, journal = {International Journal of Chemical and Molecular Engineering}, volume = {4}, number = {1}, year = {2010}, pages = {111 - 117}, ee = {https://publications.waset.org/pdf/4340}, url = {https://publications.waset.org/vol/37}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 37, 2010}, }
