     Study on NiMo Catalysts for Thiophene Hydrodesulfurization
     噻吩加氢脱硫反应中NiMo催化剂的研究
短句来源
     KIT - 1 supported MoO3 and/or NiO catalysts exhibit higher catalytic activities for thiophene hydrodesulfurization than similar MCM - 41 and NaY zeolite supported catalysts, because the three dimensional disordered network of short channels in KIT - 1 reduces the risk of blockage in the catalysts and facilitates the transport of reactant and product molecules.
     与以MCM-41和NaY分子筛为载体的Ni,Mo催化剂相比,KIT-1负载催化剂具有较高的加氢脱硫催化活性,因为KIT-1载体具有相互交错的三维孔道结构,有利于反应物和产物的扩散,而不容易受孔道堵塞的影响.
短句来源
     Property of supports showed influence on catalyst activity. Catalytic activity of NiMo supported on ZrO_2 was higher than that supported on TiO_2.Moreover,catalyst activity increased with ZrO_2 calcinations temperature from 550 ℃ to 650 ℃.
     结果表明,催化剂载体影响催化剂的性能,对于无Ni助剂的催化剂,负载在TiO2载体上的Mo催化剂活性高于负载在ZrO2上的催化剂,而助剂Ni的添加改变了活性顺序,使负载在TiO2载体上的NiMo催化剂活性低于负载在ZrO2上的催化剂;
短句来源
     Different Ni Mo catalysts based on modified single, binary and triple zeolites consisting of HMOR, H β and HZSM 5 with different compositions were prepared by impregnation method and the effects of carrier compositions on hydroisomerization and aromatization performances of the catalysts for FCC gasoline upgrading were assessed.

采用连续流动微反装置,考察了催化剂载体、载体焙烧温度、催化剂制备方法及催化剂中Ni/Mo配比对NiMo催化剂催化噻吩加氢脱硫反应性能的影响,并用BET,XRD和TPR对催化剂进行了表征。结果表明,催化剂载体影响催化剂的性能,对于无Ni助剂的催化剂,负载在TiO2载体上的Mo催化剂活性高于负载在ZrO2上的催化剂,而助剂Ni的添加改变了活性顺序,使负载在TiO2载体上的NiMo催化剂活性低于负载在ZrO2上的催化剂;催化剂制备方法影响催化剂的性能,以共浸法制备的催化剂表现出高的催化活性;Ni/Mo配比影响催化剂的性能,当Ni/Mo摩尔比为0 6时,催化剂具有最高活性。

MCM-41-HY composite molecular sieves were synthesized hydrothermally, and characterized by means of XRD, N_2 adsorption and SEM. A comparison was made between the mechanical mixture of MCM-41 and HY, and the synthesized MCM-41-HY composite molecular sieves as the hydrodesulfurization(HDS) catalyst support. Both exhibit excellent activities in the HDS hydrodesulfurization of dibenzothiophene, but, the composite shows a much lower hydrocracking activity than the mechanical mixture. It is proposed that the lower...

MCM-41-HY composite molecular sieves were synthesized hydrothermally, and characterized by means of XRD, N_2 adsorption and SEM. A comparison was made between the mechanical mixture of MCM-41 and HY, and the synthesized MCM-41-HY composite molecular sieves as the hydrodesulfurization(HDS) catalyst support. Both exhibit excellent activities in the HDS hydrodesulfurization of dibenzothiophene, but, the composite shows a much lower hydrocracking activity than the mechanical mixture. It is proposed that the lower hydrocracking activity of MCM-41-HY composite molecular sieves may be attributed to the bimodal structure in which HY zeolite is wrapped by the mesoporous MCM-41.

在水热条件下合成了包覆型MCM-41-HY复合分子筛.采用XRD、N2气吸附和SEM等方法对其进行了表征.结果表明,MCM-41-HY复合分子筛和MCM-41与H型Y沸石(HY)的机械混合物明显不同,在复合分子筛MCM-41-HY中,中孔相MCM-41附晶生长在HY沸石上,将HY包覆起来.以二苯并噻吩为模型化合物,考察了该材料担载NiMo催化剂的加氢脱硫活性.结果表明,MCM-41-HY复合分子筛与MCM-41和HY的机械混合物担载NiMo催化剂的加氢脱硫(HDS)活性相当,但MCM-41-HY复合分子筛担载NiMo催化剂的裂化活性较低.其裂化活性不同的原因在于其载体孔道结构和酸性位的分布不同.
