What are the factors that affect the reactor pressure difference? According to the Eucken equation, the factors that affect the pressure difference in a reactor include: porosity, space velocity, gas density, gas viscosity, and catalyst particle size.
Furthermore, the flow conditions within the reactor, the properties of the reactants, and the reaction conditions also affect the pressure difference. For example, at high temperatures and pressures, the viscosity of the reactants increases, resulting in an increased pressure difference in the reactor. At the same time, factors such as reactant concentration and reaction heat also affect the pressure difference. .
Porosity issue: Dust and catalyst fragmentation during catalyst loading can both lead to a decrease in porosity.
Air velocity issue: When the hydrogen-to-carbon ratio is too high, the circulation volume increases, resulting in a higher air velocity.
Catalyst pulverization issue: Catalysts are generally in the form of tablets with dimensions of φ5x5 or φ6x4. If there are problems with the quality of these tablets, pulverization can occur during loading or use.
