1Modelling-based Optimisation of the Direct Synthesis of Dimethyl Ether from Syngas in a Commercial Slurry Reactor显示文摘在现在的学习,我们开发了一个多部件为为从 syngas 和 CO2 的 dimethyl 醚(DME ) 的直接合成的一个商业催化泥浆反应堆的模拟和优化的一个维的数学模型,在搅拌机狂暴的政体操作。DME 生产率和公司变换被调节操作条件优化,例如表面的煤气的速度,催化剂集中,在臼齿的煤气的流动率(W/F ) 上的催化剂团, syngas 作文,压力和温度。反应堆建模被完成利用集体平衡,全球运动模型和异构的水动力学。在异构的流动政体,气体被散布进二个水泡阶段:小、大。模拟结果用从飞行员植物获得的数据被验证。发达模型为大规模泥浆反应堆的设计也是适用的。Sadegh Papari Mohammad Kazemeini Moslem Fattahi 2013Chinese Journal of Chemical Engineering2013,21,6:6
2Methanol to propylene: the effect of iridium and iron incorporation on the HZSM-5 catalyst显示文摘铱的效果和到丙烯反应(MTP ) 的甲醇上的 HZSM-5 沸石的铁受精被调查。丙烯和另外的烃的选择,和甲醇的变换被在小飞行员植物执行 MTP 比较。结果显示铁和铱修改的那 HZSM-5 沸石分别地增加了丙烯选择 6.3% 和 8% 。丙烯的选择比为 Fe/H-ZSM-5 为 Ir/H-ZSM-5 是更高的,在 Fe/H-ZSM-5 比 Ir/H-ZSM-5 更稳定的地方。包括 X 光检查衍射,分析技术赌了表面区域,氨的规划温度的解吸附作用,和诱导地联合的血浆原子排放光谱学,被用来象父母沸石一样描绘修改沸石。Alireza MOHAMMADREZAEI Sadegh PAPARI Mousa ASADI Abas NADERIFAR Reza GOLHOSSEINI 2012Frontiers of Chemical Science and Engineering2012,6,3:2
3Mathematical modeling of a slurry reactor for DME direct synthesis from syngas显示文摘In this paper,an axial dispersion mathematical model is developed to simulate a three-phase slurry bubble column reactor for direct synthesis of dimethyl ether(DME) from syngas.This large-scale reactor is modeled using mass and energy balances,catalyst sedimentation andsingle-bubble as well as two-bubbles class flow hydrodynamics.A comparison between the two hydrodynamic models through pilot plantexperimental data from the literature shows that heterogeneous two-bubbles flow model is in better agreement with the experimental data thanhomogeneous single-bubble gas flow model.Also,by investigating the heterogeneous gas flow and axial dispersion model for small bubblesas well as the large bubbles and slurry(i.e.including paraffins and the catalyst) phase,the temperature profile along the reactor is obtained.Acomparison between isothermal and non-isothermal reactors reveals no obvious performance difference between them.The optimum values ofreactor diameter and height were obtained at 7 m and 50 m,respectively.The effects of operating variables on the axial catalyst distribution,DME productivity and CO conversion are also investigated in this research.Sadegh Papari Mohammad Kazemeini Moslem Fattahi 2012Journal of Natural Gas Chemistry2012,21,2:2
