Abstract
The present invention is related to a selective adsorption process aimed at reducing the content of nitrogen organic compounds (NOC's) that is present in hydrotreating loads (HDT) for the production of ultra-low-sulfur diesel (ULSD below 15 ppm), which is carried out at ambient temperature, atmospheric pressure, without hydrogen, using adsorbing materials with organic metal structure MIL-101-Cr-M(MOF MIL-101-Cr-M), where Mcan be any metal cation such as Mg, Alor Ti. Likewise, the present invention considers the preparation of extrudates and the regeneration of the employed MOF adsorbent materials. In this sense, it is worth noting that the diesel HDT loads to which the present invention is referred to are hydrocarbon currents with distillation temperatures ranging from 150 to 400° C. being preferably Straight Run Gasoil (SRGO), Light Cycle OIL (LCO) and Coker Gasoil (CGO), including their blends, but oil derived fuels can be included: gasoline, diesel and jet fuel, and other hydrocarbon currents obtained from the oil refining processes, which in turn are destined to be loads of the hydrodesulfurization process (HDS) for the production of ultra-low-sulfur diesel. According to the aforementioned, it is worth mentioning that the present invention process which is the selective adsorption process of nitrogen organic compounds is designed for the pretreatment of loads that enter the HDS process, which increases the catalyst lifespan and improves the economy of the HDS process.
