This Chinese translation discusses the idea that passenger aircraft will eventually use liquid hydrogen fuel. There is a large reserve of hydrogen and hydrogen poses no danger to the environment. Hydrogen has high calorific value, high specific heat, low density and low temperature. Aircraft will ...
applications. In addition to all this, a major chunk of energy is needed to liquefy the gaseous hydrogen, that is, 30% of net calorific value of hydrogen (120MJ/kg H2). Therefore, the vehicle manufacturing companies are possibility of employing liquid hydrogen as an alternative energy storage...
Hydrogen energy is a renewable energy source with significant advantages. The vigorous development of hydrogen energy is an effective way to achieve “carbon peak and carbon neutrality” in China. In the whole industry chain of hydrogen energy, including production, storage, transportation, distribution...
The application of monthly comprehensive hydrogen content in calculation of the net calorific value of commerical coal supports all the CNKI file formats; SHENJiu-zheng - 《Coal Quality Technology》 被引量: 0发表: 2006年 METHOD OF INCREASING RESERVOIR PERMEABILITY In one configuration, the present in...
This can pertain to any specific product like bio-oil, biochar, bio-crude, syngas, or hydrogen.(15)EnergyRecovery(%)=Calorificvalueofproduct×MassofproductCalorificvalueofbiomass×Massofbiomass×100 Usually, HHV is used for the calorific value in the case of pyrolysis and HTL processes, while ...
The calorific value of the gaseous hydrogen is higher than the calorific value of the liquid hydrogen. The calorific value generated from the platinum resistance wires 2 is absorbed into the liquid if the liquid-gas sensors exist in the liquid hydrogen, but the generated heat evaporates the ...
Some hydrogen gas is produced and some carbon is deposited on the walls of the generator, but this deposited carbon can readily be burned off by cutting off the flow of fuel periodically and passing steam only through the heated generator. For example, assume that the object is to produce ...
Different types of contaminants need to be removed from the raw natural gas. Common contaminants include: Gases, helium, hydrogen sulfide, carbon dioxide, nitrogen, oxygen and water vapor Liquid natural gas condensate and...
Catalytic cracking is cheaper than hydrotreating since it does not require a costly hydrogen feed but, in general, the catalytic systems used must be quite sophisticated due to less flexibility and restrictions on the operating conditions. The reactor must also facilitate the regeneration of the ...
