What do \"hydrogenous\" and \"non-hydrogenous\" mean, and what is the difference between them? In the reactors currently in use, such as those for hydrogenous reforming, non-hydrogenous reforming, hydrogenous isomerization, non-hydrogenous isomerization, and high-pressure hydrogenation, what role does hydrogen play? How is production carried out in the absence of hydrogen?
Based on whether hydrogen is involved in the processing of oil products, these processes can be divided into hydrogenation processes and non-hydrogenation processes. The yield and quality of light oil products obtained through non-hydrogenation processes are not very high. As crude oil becomes increasingly inferior and environmental standards rise, it will be difficult to fully address the impacts on downstream processes and environmental issues resulting therefrom by using non-hydrogen-based processes. The use of hydrogenation technology can not only remove impurities from oils but also increase their hydrogen content, resulting in high-quality products with high value. As a mature and effective method for reducing the density of oils, the hydrogenation process is receiving increasing attention.

The role of hydrogen is to remove heteroatoms from oils, to saturate unsaturated hydrocarbons, to crack them, and so on. To achieve the above effects in the absence of hydrogen, catalysts are primarily relied on. Heh~~ I’ll participate. .
With the explanations for the 2nd and 3rd floors combined, the answer is perfect.
That’s true, but it doesn’t clarify the original intent of the questioner
The presence of hydrogen does not necessarily mean that it is a hydrogen-rich environment; there are temperature constraints – conditions below 250 degrees are not considered hydrogen-rich environments.
Does it need to be above 250°C to be considered in the presence of hydrogen? Are there any requirements regarding pressure?
It generally refers to a pressure greater than 1.4 megapascals. There are many people in the group who work in design; they should all be well aware of it. In other words, a pipeline containing hydrogen is generally referred to as a hydrogen-containing pipeline only when the pressure is greater than 1.4 and the temperature is greater than 250 degrees Celsius.
In my opinion, what was said on floor 8 is correct. \"Hydrogen-containing\" and \"non-hydrogen-containing\" actually refer to whether, under the conditions of the system under study, hydrogen is in a supercritical fluid state; if it is, then it is called \"hydrogen-containing XX\", otherwise it is called \"non-hydrogen-containing XX\"
Hydrogen-rich conditions refer to a temperature >250°C and a hydrogen partial pressure >1.4 MPa
Then, the reaction systems for hydrorefining and hydrocracking are all in a hydrogen-rich environment, and such an environment places high demands on the equipment.
Hydrogen-rich conditions refer to a temperature >250°C and a hydrogen partial pressure >1.4 MPa
Hydrogenation refers to the addition of hydrogen, while non-hydrogenation means no addition of hydrogen
Hydrogen-rich conditions refer to a temperature >250°C and a hydrogen partial pressure >1.4 MPa
There are 3 types of anticoagulation technologies: hydrogen-based, non-hydrogen-based, and hydrogenation-based.
