| 1 | 快速煅烧分解石灰石对其吸收CO_2和SO_2的影响显示文摘在加热过程中,应用一种新型的快速加热装置——铂膜反应器,及时准确地获得样品质量和颗粒温度,来研究石灰石的煅烧分解,并对石灰石加热速率高达750℃/s下的分解反应特性,及其对分解后产生的氧化钙吸收CO2和脱硫的化学反应特性进行了研究.实验表明,在初始加热阶段,高升温速率明显阻碍了煅烧分解的进行,这对分解后的CaO吸收CO2的效果影响不大.当加热速率升高时,石灰石分解后产生的CaO吸收CO2和脱硫过程中,钙利用率显著下降. | 阎常峰 陈勇 Grace John R Lim Jim | 2007 | 燃烧科学与技术2007,13,1: | 7 |
| 2 | 石灰石的煅烧分解及其吸收二氧化碳机理显示文摘在天然气或合成气制氢过程中,借助于石灰石煅烧分解与石灰吸收二氧化碳的化学循环反应,去除反应产物,破坏化学平衡,可以连续地驱动化学反应进行,从而提高氢气的产率,同时控制温室气体二氧化碳的排放.在多功能热重反应器(TGR)内就化学循环反应过程中的颗粒尺寸、温度煅烧分解率等对吸附剂煅烧分解和吸收特性的影响进行了比较充分的实验研究.当吸收反应温度在500℃~620℃范围内时,CaO吸收二氧化碳的反应速率与石灰石中钙的利用率都维持在比较高的水平,石灰石分解后产生的氧化钙的利用率增长比石灰石的分解率增长慢,分解率高,吸热量也高,因此,简单地提高石灰石的分解率并不是提高石灰石钙利用率的最佳选择。 | 阎常峰 陈勇 李小森 Grace J R Jim Lim | 2006 | 煤炭转化2006,29,2: | 7 |
| 3 | 天然气自热重整模块化流化床膜反应器的测试显示文摘针对燃料电池等行业对分布式高纯度氢气的需求,研发了一种新型模块化流化床膜反应器用于中小规模天然气水蒸汽自热重整制氢。在一个天然气制氢测试平台上对该反应器进行了中试研究,测试了空气引入方式对床层温度均匀性的影响,钯膜组件及催化剂的工作性能,并将反应器尾气成分与平衡态最小自由能模型预测的结果进行了比较。测试结果表明该新型模块化流化床膜反应器适于天然气自热重整制氢。 | 解东来 Adris A M Lim C J Grace J R | 2009 | 太阳能学报2009,30,5: | 6 |
| 4 | 二维导流管喷动床的流动特征显示文摘带导流管的二维喷动床(2-DSBDP)是传统喷动床的改进型式,矩形床内设置的与床同厚的垂直导流管可以控制固体颗粒的循环速率, 同时使下行区中的气固移动床维持平推流. 本文实验测定了不同表观气速、床层高度、固体颗粒与气体入口尺寸时, 二维导流管喷动床的床压降及相应的空隙率,藉以阐述2-DSBDP的流动特征. | 罗保林 Freitas L A P Lim C J Grace J R | 2000 | 化工冶金2000,21,4: | 5 |
| 5 | In vivo gastric mucosal histopathology using endocytoscopy显示文摘AIM:To study the ability of endocytoscopy to identify normal gastric mucosa and to exclude Helicobacter pylori(H.pylori) infection.METHODS:Endocytoscopic examination of the gastric corpus and antrum was performed in 70 consecutive patients.Target biopsy specimens were also obtained from the assessed region and multiple H.pylori tests were performed.The normal endocytoscopy patterns of the corpus and antrum were divided into the normal pit-dominant type(n-Pit) or the normal papilladominant type(n-Pap), respectively characterized as either regular pits with capillary networks or round, smooth papillary structures with spiral capillaries.On the other hand, normal mucosa was defined as mucosa not demonstrating histological abnormalities, including inflammation and atrophy.RESULTS:The sensitivity and specificity of n-Pit for normal mucosa in the gastric corpus were 94.4%and 97.1%,respectively,whereas those of n-Pap for normal mucosa in the antrum were 92.0%and 86.7%,respectively.The positive predictive values of n-Pit and n-Pap for H.pylori-negative tissue were 88.6%and 93.1%,respectively,and their negative predictive values for H.pylori-negative tissues were 42.9%and41.5%,respectively.The inter-observer agreement for determining n-Pit and n-Pap for normal mucosa were0.857 and 0.769,respectively,which is considered reliable.CONCLUSION:N-Pit and n-Pap,seen using EC,are considered useful predictors of normal mucosa and theabsence of H.pylori infection. | Hiroki Sato Haruhiro Inoue Haruo Ikeda Chiaki Sato Chainarong Phlanusittepha Bu'Hussain Hayee Esperanza Grace R Santi Yasutoshi Kobayashi Shin-ei Kudo | 2015 | World Journal of Gastroenterology2015,21,16: | 3 |
