利用微波辅助双模板法、软模板法制备了一系列的CeO₂/g-C₃N₄复合催化材料,通过XRD、N₂吸附-脱附、XPS、SEM和TEM等方式对材料进行表征,并对其湿式催化性能进行研究。结果表明,双模板法制备的D-CeO₂/g-C₃N₄复合材料表现出立方相CeO₂和层叠g-C₃N₄的特征,比表面积和孔径较大,属于介孔结构,表面存在Ce^₃₊和Ce^₄₊,有利于氧空位的形成。加入1 g嵌段共聚物 F127,使用无水乙醇溶液为溶剂,调节混合液呈碱性,微波辐射反应120 min后得到的D-CeO₂/g-C₃N₄(7.5)样品,结构完整均匀,具有最佳形貌特征。控制反应温度75 ℃,D-CeO₂/g-C₃N₄(7.5)投加0.7 g,H₂O₂投加 0.5 mL,初始pH值为5时,100 mg/L的苯酚溶液COD去除率可达80%以上。 D-CeO₂/g-C₃N₄(7.5) 复合催化材料使用五次以后仍可达60%以上的催化降解效果。     

以硫化反应活化能评价胶料中 不溶性硫黄的热稳定性

利用胶料的硫化反应活化能（E_a）评价胶料中不溶性硫黄（IS）的热稳定性。结果表明：含有不同热稳定性的IS胶料的硫化曲线有细微差别,但IS的热稳定性对胶料的硫化速度的影响无明显规律;胶料的E_a大小顺序与IS的热稳定性高低顺序相反,热稳定越高的IS,其胶料的E_a越小,热稳定性越低的IS,其胶料的E_a越大;胶料的游离硫元素含量及表面粘性测试结果表明,胶料中IS的热稳定性与原材料IS的热稳定性和胶料的E_a测试结果相应,利用胶料的E_a与原材料IS的热稳定性之间的关系,可以评价胶料中IS的热稳定性。     

以正硅酸乙酯和1,2-二(三乙氧基硅基)乙烷为前驱体制备微孔SiO2复合膜及其气体分离性能

This paper reports on ¬¬¬a new microporous composite silica membrane prepared via acid-catalyzed polymeric route of sol-gel method with tetraethylorthosilicate (TEOS) and a bridged silsesquioxane [1, 2-bis(triethoxysilyl)ethane, BTESE] as precursors. A stable nano-sized composite silica sol with a mean volume size of ~5 nm was synthesized. A 150 nm-thick defect-free composite silica membrane was deposited on disk support consisting of macroporous α-Al2O3 and mesoporous γ-Al2O3 intermediate layer by using dip-coating ap-proach, followed by calcination under pure nitrogen atmosphere. The composite silica membranes exhibit molecular sieve properties for small gases like H2, CO2, O2, N2, CH4 and SF6 with hydrogen permeances in the range of (1-4)107 mol•m2•s1•Pa1 (measured at 200 C, 3.0×105 Pa). With respect to the membrane calcined at 500 C, it is found that the permselectivities of H2 (0.289 nm) with respect to N2 (0.365 nm), CH4 (0.384 nm) and SF6 (0.55 nm) are 22.9, 42 and >1000, respectively, which are all much higher than the corresponding Knudsen values (H2/N2 3.7, H2/CH4 2.8, and H2/SF6 8.5).

利用两级UASB消化处理实现木薯燃料乙醇的水循环型生产

Considering limited success in target-hitting discharge from alcohol industry, our attention was directed toward a recycling use of distillery spentwash (DS) in cassava bioethanol production by using a two-stage up-flow anaerobic sludge blanket bioremediation (TS-UASBB). With the TS-UASBB, , COD, N and P in the effluent from the DS degraded significantly and their concentrations were kept at 0.2 g&#8226;L&#61485;1, 2.0 g&#8226;L&#61485;1, 1.0 g&#8226;L&#61485;1 and 15 mg&#8226;L&#61485;1, respectively, in 13 batch processes for water-recycled ethanol fermentation. With the effluent used directly as dilution water, no heat-resistant bacteria were found alive. The thirteen-batch ethanol production individually achieved 10% after 48 h fermentation. The starch utilization ratio and total sugar consumption were 90% and 99.5%, respectively. The novel water-recycled bioethanol production process with ethanol fermentation and TS-UASBB has a considerable potential in other starchy and cellulosic ethanol production.

负载型钾基CO2吸收剂的结构表征和碳酸化反应特性

The structure identification and carbonation characteristics of several potassium-based supported sorbents for CO₂ capture were investigated with TGA,XRD,XRF,SEM and N₂ adsorption method.Potassium-based sorbents were prepared by impregnation with potassium carbonate on supports,such as cocoanut activated charcoal（AC1）,coal active carbon（AC2）,silica gel（SG）and diatomite（DT）using the iso-volume impregnation method.The results showed that the K₂CO₃ loading amounts of AC1,AC2,SG and DT were 24.1%,22.5%,21.7% and 19.1% respectively.The surface area and pore volume of K₂CO₃/AC1 and K₂CO₃/AC2 were larger than others.In contrast,those of K₂CO₃/DT were small.For K₂CO₃/SG,pore volume was large but surface area was small.K₂CO₃/AC1 and K₂CO₃/AC2 showed excellent carbonation capacity.However,the carbonation capacities of K₂CO₃/SG and K₂CO₃/DT were low.The difference in carbonation capacity of those sorbents were attributed to the difference in pore structure,leading to different supported sorbents.
