Enhancing hydrogen yield and energy efficiency, decreasing hydrogen production cost and the deactivation of the catalyst, etc.

At organic loading rate(OLR) of 40 kg/(m~3·d),microflora of ethanol-type fermentation had relatively high hydrogen production rate,and the maximum specific hydrogen production rate was 550 ml/(gVSS·d),which was 3.

The biogas(hydrogen) production capacity of ethanol type and propionic acid type fermentative microflora were compared, and the movement of hydrogen production rate according to the succession of microflora from propionic acid type to ethanol type was investigated.

It was found that at an initial biomass (SS) of 15?g·L~(-1), an observed maximal hydrogen production rate of 2.

Batch acclimation of efficiency activated sludge for high concentration medium and its progress in sucrose consumption and hydrogen yield;

The results by Gompertz model show that:(1)the lag-phase time(λ),the maximal specific hydrogen rate,the specific hydrogen potential and the maximal hydrogen contents of biogas of the four pretreatment are 7.

It was demonstrated that under the same loading rate, microflora of ethanol type fermentation had relatively high hydrogen production rate and specific hydrogen production rate, maximum hydrogen production rate was 14.

The effect of reaction conditions on the gross heat efficiency were studied on the basis of mass,and energy, balance as well as the kinetics of POX in the on-board hydrogen generation process, and the suitable reaction conditions were optimized when the whole system was considered as an autothermal process.

The effect of reactor configuration and technical parameters on the gross heat efficiency and "hot spot" temperature was investigated in an autothermal operation process of methanol partial oxidation based on the balance of mass and energy balance as well as kinetics of the reactor.
