Analysis of the effect of diesel hydrodesulfurization
Thread Content
Diesel hydrogenation mainly involves two aspects: desulfurization in the reactor and refining in the distillation tower. The refining process can be roughly analyzed using the PROII simulation software (which has already been done), but no good method has yet been found for simulating diesel hydrogenation (if you know of any, please let me know). Do anyone have any effective methods to roughly assess the desulfurization effect? Controlling the temperature at the reactor inlet and outlet relies on empirical values. Could it be possible to determine the desulfurization effect through material balance calculations for the hydrogenation reaction? For example, the ratio of sulfur to hydrogen in hydrogenated sulfur is 1:2, the ratio of nitrogen to hydrogen is 1:3, and the ratio of oxygen to hydrogen is 1:2. The key factors are the known amount of feedstock, the total sulfur content in the feedstock and in the product, as well as the amount of fresh hydrogen consumed; these can be used to calculate the desulfurization effect
What is the source of the diesel used as raw material by the poster? What makes you think that the hydrogen consumption in diesel hydrogenation is mainly due to heteroatoms such as sulfur, nitrogen, oxygen, and those in hydrocarbons? The olefins in diesel are the main cause of hydrogen consumption, I suppose. You should first understand the hydrogenation process and figure out the main components of the raw material.
This requires the catalyst manufacturer to provide data; based on the manufacturer’s evaluation of the raw materials as catalysts, reaction data is then obtained
