By the researches and analyses of the fermentation type in the bio-hydrogen production system, ethanol-type fermentation bacteria had the largest H_2-production capability, butyric acid type fermentation bacteria took the second place, and propionic acid-type fermentation bacteria had the least H_2-...
Therefore, this study will explore the different carbon molecular screening films used in the pyrolysis of different hydrogen production technologies such as biomass gasification and methanol steam reforming reaction of synthesis gas separation and purification to explore, observe the transmission b ...
BATCH AND SEMI-CONTINUOUS HYDROGEN AND METHANE PRODUCTION FROM FOOD WASTE In the present study we tried to fill some existing gaps in the knowledge of fermentative H2 production from food waste. Fractions of municipal solid waste... G. CAPPAI,G. DE GIOANNIS,M. FRIARGIU 被引量: 0发表: 2013...
The chemical synthesis method can be achieved by reacting butenediol with hydrogen peroxide, then mixing its aqueous solution with an active nickel catalyst and adding inhibitor ammonia water, passing hydrogen at about 0.5MPa, and hydrogenating it to obtain erythritol products. The production efficiency...
Hydrogen can be used as a storage for renewable energy balancing the whole energy systems, and contributing to the decarbonization of the energy system, especially of the industry and the transport sector. The major objective of this paper is to discuss various ways of hydrogen production depending...
The ultrapure water also prepared by EDI process in the same EDI unit using two different types of commercial membranes (Ionsep and Fujifilm type II). The resistance of ultrapure water was 18.2 MΩ cm with the interpolymer based membranes at 25 V/cell pair applied potential, whereas with ...
Then different hydrogen production schemes are compared to obtain the most favorable solution. To explore the potential of the electrolysis, the scenario analysis of the power structure is conducted. The results show that the most mineral resources are consumed in the raw material acquisition stage, ...
