The reaction of complexes (η5‐C5H4R)CoLI2 [L= CO, R= ‐COOC(CH3) = CH2 (1), ‐COOCH2C6H5(2); L=PPh3, R=‐COOC (CH3) = C... hiện toàn bộ
Reforming of CH4 with CO2 over Rh/H‐Beta: Effect of Rhodium Dispersion on the Catalytic Activity and Coke Resistance
Chinese Journal of Chemistry - Tập 28 Số 10 - Trang 1864-1870 - 2010
Linping Qian, Bin Yue, Yongming Zhang, Li Zhang, Lin Ye, Jifang Cheng, Shik Chi Edman Tsang, Heyong He
AbstractThe effect of Rh dispersion on reforming of CH4 with CO2 over H‐Beta supported Rh catalysts has been investigated. The CH4 and CO2 conversion over the catalysts increase with increasing Rh loading from 0.5 wt% to 4.0 wt% in the reaction temperature range of 823–1123 K. The high TOF of CH4 over 0.5 wt% and 1.0 wt% Rh/H‐beta may be attributed to high dispersion of rhodium species. The cataly... hiện toàn bộ
(Solid+Liquid) Equilibria in the Quaternary System Na2B4O7‐MgB4O7‐K2B4O7‐H2O at 288 K
Chinese Journal of Chemistry - Tập 28 Số 5 - Trang 755-758 - 2010
Song Shihua, Jiang Peng
Abstract(Solid+Liquid) phase equilibria in the quaternary system Na2B4O7‐MgB4O7‐K2B4O7‐H2O at 288 K were studied experimentally using the method of isothermal solution saturation. Solubility of any single salt in the solution of the quaternary system was determined experimentally. Based on the experimental data achieved, the phase diagram and water content diagram of the quaternary system were con... hiện toàn bộ
