| 1 | 负载型磷钨酸对柴油催化氧化脱硫显示文摘采用过量浸渍法和吸附法把磷钨酸(PW12)负载在TiO2、改性Y分子筛(GY)、AC载体上,并用负载后的催化剂对柴油(含硫量540 mg.L-1)进行催化氧化脱硫,结果表明,3种催化活性强弱顺序为:GY>TiO2>AC,且当GY上负载PW12的质量分数为30%的PW12/GY催化脱硫效果最好。对催化剂进行了酸强度测定、比表面测定,对GY进行了XRD表征,研究了GY负载磷钨酸催化剂在氧化脱硫反应中的催化活性和稳定性,实验结果表明,负载PW12质量分数为30%的PW12/GY表现为超强酸性和近超强酸性比,表面积有462 m2.g-1。其在最适宜的反应条件下催化氧化柴油,脱硫率可达95.3%:20 mL柴油,0.08 g催化剂,过氧化氢与硫的摩尔比为7,反应温度343 K,反应时间70 min,V(NMP):V(oil)=1:1萃取3次。 | 黎先财 杨春燕 黄绍祥 徐庆荣 刘厚凡 | 2009 | 南昌大学学报(理科版)2009，33，6： | 11 |
| 2 | Hydroisomerization of n-heptane over bimetal-bearing H_3PW_(12)O_(40) catalysts supported on dealuminated USY zeolite显示文摘The bimetal-bearing (CePt or LaPt) 12-tungstophosphoric acid (H3PW12O40 (PW)) catalysts supported on dealuminated USY zeolite (DUSY) were prepared by impregnation and characterized by XRD, BET, IR, and H2-chemisorption. Their catalytic activities were tested in the hydroisomerization of n-heptane with a continuous atmospheric fixed-bed reactor. After the steam treatment combined with the acid leaching, as well as the supporting with PW and the bimetals, the DUSY support retains the Y zeolite porosity and the PW well keeps its Keggin structure in catalysts. The doping of Ce into the catalysts enhances the dispersion of Pt on the catalyst surface. The Pt-bearing PW catalysts doped with Ce or La, especially Ce, exhibit much higher catalytic activity and selectivity than the catalysts without dopants at lowered reaction temperatures. At the optimal reaction conditions, i.e., the reaction temperature of 250℃ and WHSV of 1.4 h1, the catalyst with a Pt loading of 0.4%, PW loading of 10% and a molar ratio of Ce to Pt of 15:1 shows a conversion of n-heptane of 70.3% with a high selectivity for isomerization products of 94.1%. | WEI RuiPing1,2, GU YanBo1 & WANG Jun1 1 State Key Laboratory of Materials-Oriented Chemical Engineering, College of Chemistry and Chemical Engineering, Nanjing Uni- versity of Technology, Nanjing 210009, China 2 College of Chemistry and Chemical Engineering, Southeast University, Nanjing 211189, China | 2008 | Science China Chemistry2008，51，2： | 5 |
| 3 | 脱铝改性Y分子筛催化清洁合成乙酰水杨酸显示文摘以水杨酸和乙酸酐为原料,脱铝改性分子筛为催化剂合成了乙酰水杨酸.考察催化剂用量、水杨酸和乙酸酐物料配比、反应时间、反应温度等因素对该反应的影响.结果表明:当n(水杨酸):n(乙酸酐)为1.0∶1.2,催化剂用量为水杨酸质量的7.5%,80℃,反应10 min,产物收率达94.2%. | 张康华 徐庆荣 曹小华 陈义凡 陶春元 | 2009 | 信阳师范学院学报(自然科学版)2009，22，2： | 3 |
