Definitions
- the present invention relates to a process for the purification of light hydrocarbons containing sulfur and / or nitrogen compounds refractory to conventional catalytic hydrotreatments, such as thiophene compounds and pyrrole type compounds, by oxidative polymerization of these compounds. It also relates to the regeneration and reactivation of the oxidizing agent used in this process. This process is intended more particularly for the treatment of gasolines, in particular gasolines from catalytic cracking, and hydrocarbons from steam cracking of naphthas containing refractory compounds.
- thiophene By compounds refractory to the usual catalytic hydrotreatments is meant thiophene, benzothiophene and their alkylated derivatives, as well as pyrrole and its derivatives, benzopyrrole and carbazole, optionally alkylated.
- thiophenic essences are introduced into more desulphurized direct distillation essences, which are sold in service station networks, and it is essentially these thiophenic compounds contained in thiophenic essences that generate sulfur dioxide from automobile exhaust.
- the nitrogen compounds present in these products are known for their harmful effect with regard to the activity and the lifetime of the catalysts used.
- these refractory compounds are well known to manufacturers for the difficulty that there is in eliminating them.
- the preferred solvents are generally compounds capable of complexing aromatic compounds contained in hydrocarbons, such as alkylene carbonates, benzonitriles, sulfolanes or alternatively derivatives of morpholine.
- hydrocarbons such as alkylene carbonates, benzonitriles, sulfolanes or alternatively derivatives of morpholine.
- salts tetraalkylammonium salts are used, such as fluoroborates, fluorophosphates or halides.
- the Applicant it has studied a process for the purification of light hydrocarbons containing sulfur and / or nitrogen compounds refractory to catalytic hydrotreatments, which aims to weigh down these compounds by oxidative polymerization thereof, in order to extract them more easily from these hydrocarbons .
- the Applicant seeks both desulfurization and denitrogenation, but also the regeneration of the activity of the oxidizing agent used, by combining the oxidation reaction with a regeneration and activation process. the oxidizing agent used.
- the metal cations are introduced in liquid form, dispersed or dissolved in an aqueous or organic liquid or else supported on a solid.
- the method according to the invention is therefore a multiphase method with two or three phases, depending on whether the metal cations are deposited or not on a solid support before the start of the reaction implemented in this process, namely a polymerization of the sulfur and / or nitrogen compounds.
- the polymerization reaction is carried out at ambient temperature, under atmospheric pressure, at an hourly space velocity (wh) of at least minus O. l - 1 .
- the oxidizing metal cation must have a redox potential greater than that of the molecule to be oxidized / polymerized in the reaction medium.
- the metal cation is chosen from the cations of metallic elements from the group consisting of iron, copper, molybdenum, cerium, manganese and vanadium, each of these metals to be present in the reaction with an oxidation state of at least 2.
- metal cations are used in the form of salts of the group consisting of halides, nitrates, citrates, carboxylates, phosphates, sulfates, persulfates, borates, perborates and bi- and polydentate complexes in linear or cyclic form, comprising nitrogen, sulfur and / or oxygen atoms as a coordinating element.
- bi- and polydentate complexes is meant, without this having a limiting character, phthalocyanines, porphyrins, cyclams, bi-pyridines and Saler complexes.
- the polymerization reaction is biphasic liquid / liquid (organic / aqueous), and the polymers formed and the oxidizing cations can be eliminated by decantation of separate phases. , by filtration and / or extraction according to techniques known per se to those skilled in the art.
- the process is carried out in the presence of a solid chosen from the group consisting of carbon, clays, zeolites, molecular sieves, amorphous silica aluminas, alkali silicates , silica-borates, silica-magnesia, and aluminophosphates.
- This solid can withstand the salts of the metal cations necessary for the invention, whether or not there is ionic interaction between these cations and these solids.
- the protons initially present on the support were exchanged for the metal cations, then these metal cations were oxidized before use, which makes it possible to obtain a higher oxidation state of these metals or equal to two.
- This oxidation state is essential for the polymerization reaction to occur in hydrocarbons, as M. Bein had already observed for less complex media than hydrocarbons from petroleum distillation, in his article in Studies in Surface Science and Catalysis, vol. 102, 1996, pp 295-319.
- the advantage of a process using the metal cation in the form of a counterion of a solid support is to be able to carry out the polymerization reaction under usual refining conditions, that is to say with a catalytic bed. of the type used in refining.
- Another advantage is to be able to envisage the in situ or ex situ regeneration of the metal cations used as an oxidizing agent.
- As support for these metal cations it is possible to choose crystalline or amorphous solids, cation exchangers, containing at least one metal from the group of elements consisting of silicon, aluminum, zirconium, titanium, germanium, gallium. and boron, taken alone or in combination, and whose specific surface is at least 10 cm / g.
- these supports are chosen from clays, including bentonites, and zeolites, including Sapo, Alpo and Beta, and mesoporous, for example of the MCM 41 type, molecular sieves, amorphous alumina silicas, alkali silicates , silica-borates, silica-magnesia, these solids having a pore size of between 1.5 nm and 200 nm.
- metal cation salts in the form of an aqueous or organic solution
- the salts being chosen from nitrates, carboxylates, sulfates, persulfates, citrates, phosphates, borates, perborates and halides of metals, including iron, copper, molybdenum, manganese, vanadium and cerium.
- Preferred salts are chosen from ferric chloride, cuprous chloride, molybdenum chloride, vanadium oxychloride and cerium chloride.
- the amount of metal cation present on the support can vary from 0.1% to 30% by weight of the metal corresponding to said cation.
- Such supported cations can act in a fixed bed, moving bed, fluidized bed or suspension in a liquid process.
- the polymers formed are entrained in suspension in the hydrocarbon or deposited on the solid. They can therefore be extracted, decanted, filtered or even distilled, in order to be eliminated from the hydrocarbon thus purified.
- the elimination step consists in extracting the polymers deposited on the support by washing with solvent, in particular by filler, by desorption by a current of inert gas chosen from helium, l nitrogen, carbon dioxide and water vapor, at a temperature above 100 ° C, and / or by combustion by injection of air or oxygen, preferably after removal of the light hydrocarbons still present on the particles of support.
- solvent in particular by filler
- inert gas chosen from helium, l nitrogen, carbon dioxide and water vapor
- This step of oxidizing the metal cation, supported or not, consists in putting the metal cations in an oxidation state of at least 2, by oxidation, by injecting air or liquids containing peroxides or other more oxidizing metal cations, possibly by simultaneously increasing the temperature of the oxidizing agent.
- steps taken alone or in combination combine in a continuous or discontinuous process.
- the oxidized metal cation is directly reused for a new oxidative polymerization step.
- this process can be used for the desulfurization / denitrogenation of gasolines produced by catalytic cracking and of steam cracker effluents, in particular pyrolysis gasolines.
- This process can also be applied as a finishing treatment for aromatic effluents such as benzene, toluene and xylene.
- aromatic effluents such as benzene, toluene and xylene.
