| 2 | Microwave energy inductive fluidized metal particles discharge behavior and its potential utilization in reaction intensification显示文摘Microwave-induced metal discharge(MMD)technology offers a novel methodology for efficient gas-phase catalytic reaction due to its unique heating effect,plasma effect and discharge effect.Herein,we successfully used a special kind of uniformly distributed particles with synergistic microwave-induced fluidized-metal discharge(MFD)effect.A lab-scale atmospheric quartz tube fluidized bed reactor was designed.Apparatus like highspeed camera,fiber spectrometer and infrared thermometer were used to record the discharge phenomena.The effects of operating conditions such as gas velocity,microwave power,carrier gas type,and metal type on the discharge behavior were investigated in detail.Subsequently,the MFD was applied into the methane dry reform reaction(MDR)with excellent conversion compared with the conventional heating conditions.Gratifyingly,the metal particles can both be the converter of microwave and the catalyst of the reaction.The reported conclusion provides a novel way to intensification the reaction process and utilize microwave energy. | Xingang Li Chuanrui Pang Hong Li Xin Gao | 2021 | Chinese Journal of Chemical Engineering2021，34，5： | 2 |

| 4 | 微波化学反应的无量纲准数动力学模型研究:以偶氮二异丁脒盐酸盐(AIBA)分解反应为例显示文摘微波辅助化学已成为备受关注的研究课题,但微波反应动力学模型缺乏系统的研究严重阻碍了微波在化学工业化上的应用,微波化学反应在化学工程化的放大设计及应用缺乏基础依据。以偶氮二异丁脒盐酸盐(AIBA)分解反应为例,通过选择合适的溶剂调整其复配比例,得到一系列具有不同沸点的混合溶剂作为反应介质,使反应在混合溶剂沸点下进行,以保证反应过程中微波的持续作用来研究微波反应动力学。从微波作用下动量传递、热量传递和质量传递的影响因素进行考虑,选择了对微波化学反应必须和充分的因素,包括微波功率密度p、黏度μ、密度ρ、反应物的浓度CA、温度T、热导率λ、损耗角正切δ和微波辐射频率f。采用量纲分析方法,通过模型分析建立了微波分解反应动力学模型。通过大量的实验数据进行拟合,回归出特定反应的模型参数。该模型估算值与实验值的误差较小,相关性较高,具有一定的预测能力可解决微波反应过程放大的基础性问题,有望用于指导微波工业化生产。 | 毛桃嫣 邹敏婷 郑成 曾昭文 伍旭贤 肖润辉 彭思玉 | 2021 | 化工学报2021，72，3： | 0 |
| 5 | 微波强化液桥式螺旋降膜蒸发器数值模拟显示文摘微波加热薄膜蒸发技术在促进极性/非极性混合物分离领域潜力巨大,但仍面临着能源利用效率低和加热不均的挑战,而电场分布不均是其根本原因,但影响电场分布的因素十分复杂且不可控,因此,从蒸发器结构及流体流动形式视角出发可为解决微波能高效利用的瓶颈提供新思路。为此本文提出了液桥式螺旋降膜蒸发器,通过COMSOL建立三维模型并模拟计算了微波能强化蒸发器上的螺旋降膜流动与蒸发过程,以蒸发率和温度变异系数作为评价指标,探究液膜厚度、螺距、蒸发器直径、流量以及时间对微波能利用效率的影响规律,研究结果表明该种结构在一定微波入射功率下,液膜蒸发率可达29.26%,温度变异系数降至0.0867,为微波能强化蒸发分离装置的设计提供了依据。 | 张亚爽 李洪 从海峰 韩红明 李鑫钢 高鑫 | 2021 | 化工学报2021，72，S01： | 0 |
