Abstract: In order to provide the scientific and practical basis to the industrial test of methanol catalytic synthesis from cornstalk syngas, the systemic research about the reaction conditions of methanol catalytic synthesis over a domestic Cu-based catalyst C301 was carried out in a tubular-flow integral and isothermal reactor. The reaction temperature, the cornstalk syngas proportion and the entrance syngas flow rate were optimized under the reaction pressure of 5MPa and the credible results were obtained.

Abstract: The start-up characteristics of internal circulation anaerobic reactor were studied using anaerobic sludge of UASB as vicinal sludge. The concentration of influent COD was kept at 2500mg/L initially, then the influent flow increased from 1L/h to 2.5L/h gradually, and the removal rate retained around 85.0% to 93.5%. During the middle-period of the experiment, the influent flow was maintained at 2.5L/h, and the influent COD concentration was gradually increased from 2500mg/L to 10500mg/L, the removal rate of 91.2%~94.6% was obtained now. At the end period of the experiment, the influent COD concentration was kept at 10500mg/L, and the influent flow was increased from 2.5L/h to 3L/h gradually. When the volume loading was improved to 55.04kg COD/ (m3 • d), the COD removal rate reached 88.3%.
