The center of the reactor is filled with catalyst for catalyzing the chemical reaction of gas containing hydrogen and the air, so that catalytic combustion reaction of the tail gas containing the hydrogen and the oxygen in the air by the aid of the catalyst without heating and pressurizing, ...
However, modern gas turbines have been optimized to operate on methane-air combustion and several challenges, notably thermo-acoustic instability, arise when using other fuels or oxidizers because of their different thermochemical and transport...

Before introducing electrochemical reactions in fuel cells, the chemical reactions of hydrogen-oxygen combustion should be discussed: (1.1)H2+12O2→H2O+Q where Q is the reaction heat in kJ mol−1. From a macroscopic view, the heat released by hydrogen combustion can be used as energy. From...
In addition, the typical carbonization of the ZIF-based catalysts was conducted by first putting them within a combustion boat made of porcelain and then transporting them into a tube furnace. The samples were heated using N at a flow rate of 5 °C/min and carbonized for 3 h at 450 °C...
The atomization characteristics of oxidizer gas/kerosene shear coaxial injection are influenced by the following the two parameters: Conclusions The complex H2O2/kerosene turbulent flow and combustion chemical reaction are modeled. During the kerosene injection, the spray angle is 13°, the lasting time...

However, when the temperature is too high, gas molecules move faster and desorb before they have time to participate in the gas-sensing reaction. Hence the responses of SGO exhibit a trend of “increase-maximum-decrease” as the operating temperature increases. The optimum working temperature for...
Results of the testing show that small-scale fuel-air mixing can deliver a reliable, low-NOx solution to hydrogen combustion in advanced gas turbines. 展开 关键词: Combustion systems Gas turbines Testing Hydrogen DOI: 10.1115/GT2012-69913 被引量: 26 ...
The product of hydrogen reaction with oxygen either in an electrolyzer or in a combustion process is water vapor. At room temperature, the reaction of hydrogen and oxygen is immeasurably slow; however, an electric spark or a catalyst, such as platinum, can significantly accelerate the reaction. ...
Hydrogen fuel cells generate electricity through a chemical reaction between hydrogen and oxygen. In a fuel cell, hydrogen gas is fed into the anode where a catalyst causes the hydrogen molecules to split into protons and electrons. The protons pass directly through a membrane to form water, whic...
