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-MX+ (MOF MIL-101-Cr-MX+), where MX+ can be any metal cation such as Mg2+, Al3+ or Ti4+. 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.

Abstract: The present invention relates to a process for obtaining materials with Metal Organic atomic structure and called MOF (MOF: Metal Organic Framework) type MIL-101 (Cr) and MIL-101-Cr-MX+ (MIL: Material from Institute Lavoisier), where MX+ can be any metal cation, such as Mg2+, Al3+ or Ti4+, using for its synthesis metal epoxides and alkoxides, avoiding the use of hydrofluoric acid (HF) or bases as synthesis controlling agents. The process of the present invention for the preparation of materials MOF MIL-101 (Cr) and MOF MIL-101-Cr-MX+ where MX+ can be any metal cation, such as Mg2+, Al3+ or Ti4+, consisting of: a) Synthesizing MOF MIL-101 (Cr) with epoxides, or Synthesizing MOF MIL-101-Cr-MX+ with metal alkoxides; and b) Purifying the synthesized MOF. in order to obtain 100% pure materials, with a controlled mesoporosity associated with a hysteresis P/P0 from 0.7 to 0.99, BET surface area from 2,500 to 3,500 m2/g, pore volume from 1.1 to 2.2 cm3/g, and pore diameter from 15 to 55 nm.

Abstract: Methylcarbonate-based ionic liquids (LIs) or carboxylates, derived from aliphatic or aromatic carboxylic acids are provided for the extraction of nitrogen compounds from hydrocarbon mixture (HCs) by liquid-liquid selective extraction, at room temperature and atmospheric pressure, where the LIs are immiscible with the HCs. This process is performed through an extraction by stifling two phases, followed by separation, or in a continuous flow system where the nitrogenous compounds are transferred to the phase formed by the LI and the total nitrogen content is substantially reduced in the HCS phase. The ionic liquids have the general formula C+A?, where: C+ is a heterocyclic organic cation, or quaternary ammonium-based; and A? is a methylcarbonate- or carboxylates-based anion, derived from aliphatic or aromatic carboxylic acids.

Abstract: The present invention is related with the application of an adsorbent material of microporous carbon (MCA), prepared from the direct pyrolysis of copolymers generically known as Saran, in adsorption processes to reduce the benzene content in naphtha boiling range hydrocarbon streams, between 27 and 191° C., in which is preferable to perform a first separation by distillation of the C6's fraction, and a further separation of Benzene by adsorption through an adsorbent material bed, obtaining the fraction of C6's free of Benzene and an adsorbent with Benzene, which is further regenerated by pressure or temperature swing desorption or by displacement using a desorbent such as an inert gas at high temperature or by passing a desorbent which after the process, the desorbent and Benzene are separated by distillation. The fraction of C6's free of Benzene is reintegrated to the hydrocarbon stream and providing a gasoline with a Benzene content less than 1 volume %.
