摘要
以红螺菌科光合细菌为实验菌种,采用单因子实验的方法,研究了高粱秸秆光合产氢体系的流变特性,结果表明:在颗粒总质量不变的情况下,颗粒粒径变小,颗粒间的相互作用强度增强,体系的流动性降低,使得超微秸秆产氢体系的相对粘度增加最快,体系浊度液一直处于最大水平,超微处理有利于产氢反应的进行,但产氢反应主要是在体系粘度最大和其减小的过程中发生。此研究以期为超微秸秆光合产氢体系的传质、传热和速度场分布奠定理论基础。
The rheological properties on Rhodospirillaceae photosynthetic bacteria hydrogen production system were studied. The results show that the total mass of particles without change, the smaller particle size enhanced the strength of the interaction between the particles, reducing the liquidity of the system. The relative viscosity of hydrogen production system with ultramicro sorghum is higher than other granularity, and its turbidity of the system is the highest in the process of hydrogen production. Ultramicro deal was conducive to hydrogen production, but the capacity of hydrogen production lagged behind turbidity and viscosity changes. This study has laid a theoretical foundation on mass transfer, heat transfer and velocity field distribution of photosynthetic hydrogen production sys- tem.
