1Cu-MgO/USY催化甘油氢解制丙二醇(英文)显示文摘以USY为载体制备了一系列不同Cu和MgO负载量的酸碱双功能催化剂Cu-MgO/USY用于甘油氢解制丙二醇反应,并采用X射线粉末衍射、透射电镜、傅里叶红外光谱、NH3程序升温脱附等手段对该催化剂进行了表征.结果表明,负载后的USY载体其Y沸石特征峰保持完整,且MgO的加入提高了Cu在载体表面的分散度.在200 oC,3.5 MPa H2下反应10 h以及6%催化剂0.2Cu-MgO/USY(0.2 g Cu与1.0 g MgO负载于1.0 g USY上面)用量的条件下,甘油转化率达到83.6%,1,2-丙二醇及1,3-丙二醇的选择性分别为40%和19.4%.牛磊 魏瑞平 杨慧 李想 姜枫 肖国民 2013催化学报2013,34,12:9
2Activity and basic properties of KOH/mordenite for transesterification of palm oil显示文摘The catalytic performance of KOH/mordenite has been studied for transesterification of palm oil using a batch reactor and a packed-bed reactor at 60 C and atmospheric pressure.The KOH/mordenite processed transesterification in the batch reactor gave the highest methyl ester yield of96.7%under optimum conditions,while a methyl ester content over 94.5%was obtained in the packed-bed reactor.This comparison indicates that transesterification in a batch-type reactor gives a higher methyl ester yield than that of a continuous-flow reactor.Dealumination was found in the calcined catalysts and had a significant effect on the physical structure and chemical composition of the catalysts.Leaching of the potassium species was negligible,whereas depositing and washing of the reacted mixture with acetone on the catalyst surface were observed by FTIR.Pisitpong Intarapong Sotsanan Iangthanarat Pitchaya Phanthong Apanee Luengnaruemitchai Samai Jai-In 2013Journal of Energy Chemistry2013,22,5:7
3Catalytic performance of acidic ionic liquid-functionalized silica in biodiesel production显示文摘Acidic ionic liquid([BsAIm][OTf]) was immobilized on sulfhydryl-group-modified SiO2(MPS-SiO2) via free radical addition reaction. The[BsAIm][OTf] loading on acidic ionic liquid-functionalized silica([BsAIm][OTf]/SiO2) was controlled through tuning the sulfydryl(SH)content of MPS-SiO2. All the samples were characterized by FT-IR, elemental analysis, N2adsorption-desorption measurements and TGDTA. The catalytic performance of [BsAIm][OTf]/SiO2in the esterification of oleic acid and the transesterification of glycerol trioleate for biodiesel production was investigated. The results showed that with the increase of [BsAIm][OTf] loading on SiO2the specific surface area and pore volume of [BsAIm][OTf]/SiO2decreased, and the pore diameter of [BsAIm][OTf]/SiO2narrowed. In the esterificaiton of oleic acid, the oleic acid conversion increased with the increasing [BsAIm][OTf] loading. In the transesterification of glycerol trioleate, with the increasing[BsAIm][OTf] loading the glycerol trioleate conversion decreased and the selectivities to glycerol monooleate and methyl oleate increased.Bin Zhen Qingze Jiao Qin Wu Hansheng Li 2014Journal of Energy Chemistry2014,23,1:3
4Synthesis of Biodiesel Using ZrO_2 Polycrystalline Ceramic Foam Catalyst in a Tubular Reactor显示文摘With the help of the ceramic foam research efforts and preparation techniques, the ZrO2 polycrystalline ceramic foam catalyst was synthesized, and its characteristics, including the crystal structure, the phase composition, the acid–base properties, and the microstructure, were analyzed by XRD, SEM, Py-IR, and BET techniques. The performance of the ZrO2 polycrystalline ceramic foam catalyst in a tubular reactor was investigated via biodiesel synthesis using S. wilsoniana oil and methanol. The effects of reaction conditions(i.e., reaction temperature, reaction pressure, and volume ratio of methanol to S. wilsoniana oil) on transesterification efficiency were investigated, and the reaction conditions were optimized using RSM. The optimum reaction temperature, reaction pressure, and volume ratio of methanol to S. wilsoniana oil were determined to be 290 ℃, 10 MPa, and 4:1, respectively. Under this condition, the FAME content in the product oil reached 98.38%. The performance of the ZrO2 polycrystalline ceramic foam catalyst synthesized in this work for biodiesel synthesis from S. wilsoniana oil with a moisture content of 7.1% and an acid value of 130.697 mg KOH/g was examined, and the FAME content in the product oil was found to be 93% and 97.67%, respectively. The FAME content in the product oil exceeded 97% after five consecutive cycles(12 h per cycle of use) of the catalyst. The proposed catalyst represents a new type of solid catalyst with excellent acid resistance, water resistance, esterification efficiency, and catalytic stability.Wang Yunpu Fan Liangliang Dai Leilei Liu Yuhuan Ruan Roger Liu Shitao Zhang Xueqin Wan Yiqin 2015China Petroleum Processing & Petrochemical Technology2015,17,3:3

6钐掺杂改性γ-Al_(2)O_(3)粉体的热稳定性研究显示文摘以硝酸铝(Al(NO_(3))_(3)·9H_(2)O)为氧化剂,甘氨酸(C_(2)H_(5)NO_(2))为还原剂,硝酸钐(Sm(NO_(3))_(3)·6H_(2)O)为改性剂,通过溶液燃烧法合成了γ-Al_(2)O_(3)粉体。采用XRD、SEM、BET、TG-DTG等手段对产物进行表征,并分析探讨了焙烧温度、改性剂添加量对产物物相的影响。实验结果表明:在硝酸铝(Al(NO_(3))_(3)·9H_(2)O)与甘氨酸(C_(2)H_(5)NO_(2))的物质的量之比为3∶5,改性剂Sm(NO_(3))_(3)·6H_(2)O添加量为1%,焙烧温度为1025℃,焙烧时间为4 h的条件下可以制备具有较高热稳定性的γ-Al_(2)O_(3)粉体,且该粉体具有比表面积较大、结构稳定等特点,可以作为催化剂的载体。王立明 贾雅薇 孟竺 付丽婷 吴静 宋丽娟 储刚 2023稀有金属与硬质合金2023,51,3:0
7高岭土负载KF固体碱催化制备乙二醇单甲醚酯显示文摘以高岭土为载体,采用浸渍法制备了高岭土负载KF固体碱催化剂,并用于月桂酸甲酯(ML)与乙二醇单甲醚(EGME)的酯交换制备乙二醇单甲醚月桂酸酯(EGMEML)反应,考察了不同KF负载量催化剂的用量、醇酯摩尔比、反应时间和反应温度等条件对EGMEML收率的影响。通过XRD、SEM、FTIR、CO_2-TPD和N_2吸附-脱附等方法对催化剂结构进行了表征。表征结果显示,KF负载高岭土固体碱催化剂中,出现了K3AlF_6晶相,且随KF负载量增加,碱量明显增加,催化活性显著提高。实验结果表明,在催化剂用量为4.5%(w)(基于EGME)、n(EGME)∶n(ML)=3.0、反应时间6h、反应温度120℃的条件下,催化剂表现出良好的活性,E GMEML收率可达92.0%;当KF负载量为15%(w)时,催化活性最强。催化剂的高活性可能与KF和高岭土作用生成的K_3AlF_6有关,催化剂重复使用后,仍保持较高活性和稳定性。贾丽华 娄升凤 周丹丹 郭祥峰 于露 2016石油化工2016,45,10:0
