Definitions
- the present invention relates to a desulfurization process hydrocarbons, in particular desulfurization of the bases of fuels for diesel, kerosene and gasoline. It concerns in particular the desulfurization of the fuel bases loaded with dibenzothiophenic compounds.
- refineries use processes catalytic hydrodesulfurization to lower the sulfur content of fuels.
- the gas oils coming directly from the distillation are hydrotreated between 300 and 400 ° C, under a hydrogen pressure varying between 30 and 100 bars (30 to 100.10 5 Pa), in the presence of a catalyst placed in a fixed bed and constituted metal sulfides of groups VIb and VIII deposited on alumina, for example cobalt and molybdenum sulfides or nickel and molybdenum sulfides.
- a catalyst placed in a fixed bed and constituted metal sulfides of groups VIb and VIII deposited on alumina, for example cobalt and molybdenum sulfides or nickel and molybdenum sulfides.
- the size of the reactor can be multiplied by 4 and the quantity of hydrogen necessary for the reaction should be increased by about 20%. It is particularly difficult, by such methods, to remove traces of sulfur, especially if the sulfur belongs to refractory molecules such as dibenzothiophene alkylated in position 4, and and 6.
- gasolines do not come from only from the direct distillation of crude oil, these essences being then weakly sulfur, but can also be obtained by several processes such as naphtha reforming, isomerization light naphthas, butane or propane alkylation producing isooctane, methoxylation of isobutene and catalytic cracking vacuum distillates or atmospheric residues.
- catalytic cracking provides between 20 and 60% by weight of the petrol final.
- These essences contain up to 0.1% by weight of sulfur. he It is therefore common to desulfurize gasolines from cracking catalytic by processes similar to those described for hydrodesulfurization of gas oils, for which the conditions are more severe in hydrogen pressure, space velocity and temperature.
- hydrodesulfurization is not only ineffective with respect to thiophene compounds, but it is also destructive to the octane number of gasoline. Indeed, during of the hydrodesulfurization reaction, there is partial hydrogenation of olefins contained in these cracked essences, their disappearance resulting in a drop in the octane number of gasoline and therefore a deterioration in the quality of petrol. To compensate for this loss, there it is possible to introduce other constituents to improve this index or to reprocess the essence itself to increase this index. Adding additive or reprocessing to improve the quality of petrol strikes its cost price all the more, and it is therefore advantageous to have a treatment process allowing direct elimination refractory sulfur compounds, such as derivatives benzothiophenics, limiting the use of hydrogen.
- Another method consists of producing a desulfurized hydrocarbon material in three processing steps.
- the first step is to oxidize at least partially the sulfur compounds by contacting with peroxides, in the presence of metal catalysts containing metals of the group including titanium, zirconium, molybdenum, tungsten, vanadium, tantalum, chromium and their mixtures, under liquid or solid form possibly supported, the supports not being not essential for the reaction.
- the second step is to put in contact the hydrocarbonaceous material containing these oxidized compounds with another metallic component, metallic oxide or peroxide (metals from the group comprising nickel, molybdenum, cobalt, tungsten, iron, zinc, vanadium, copper, manganese, mercury and their mixtures), at a temperature varying from 250 to 730 ° C, under pressure hydrogen.
- metallic oxide or peroxide metal from the group comprising nickel, molybdenum, cobalt, tungsten, iron, zinc, vanadium, copper, manganese, mercury and their mixtures
- the present invention therefore aims to propose a method of desulfurization of hydrocarbons, especially those used as fuel bases containing thiophenic derivatives, without decrease in the octane number or cetane number index, sometimes even with an increase in these indices. It relates to particularly the finishing treatment of hydrotreated gas oils, kerosene and gasoline from catalytic cracking, strongly concentrated in thiophenic derivatives refractory to hydrogenations.
- the invention further aims to propose such a method which allows to reach identical oxidation levels, otherwise superior to known methods, while limiting reaction times and separation of oxidized sulfur compounds from hydrocarbons desulphurized.
- the present invention therefore relates to a process for the selective desulfurization of thiophenic compounds contained in hydrocarbons obtained from the distillation of crude oil, refined or not, consisting in oxidizing thiophenic sulfur atoms to sulfones in the presence of an oxidizing agent and d 'a catalyst, and to separate the sulfonated compounds obtained from said hydrocarbons, this process being characterized in that it comprises at least a first oxidation / adsorption step by heterogeneous catalysis of the sulfur-containing compounds, in organic medium, at a temperature d '' at least 40 ° C, in the presence of an organic oxidant from the family of peroxides and peracids and in the presence of a catalyst with a specific surface greater than 100 m 2 / g and a porosity varying from 0.2 to 4 ml / g, and a second stage of regeneration of the spent catalyst, the regeneration stage always succeeding the oxidation / adsorption stage.
- derivatives thiophene benzothiophenic, polybenzothiophenic compounds and their alkylated derivatives, among which the alkyldibenzothiophenes, particularly refractory to the processes of conversion usually used by refiners.
- the method according to the invention has the advantage, on the one hand, to ensure at atmospheric pressure an oxidation of the entire sulfur contained in hydrocarbons and more selectively a conversion of thiophene derivatives into sulfones, and this in the context of a simple industrial process, and, on the other hand, to adsorb simultaneously these sulfoxidized compounds on the catalyst.
- the separation of hydrocarbons from most of the sulfones and sulfoxides formed is immediate, the latter being found under solid form deposited on the catalyst or in the form of filterable deposit by means known per se, in the treated hydrocarbons.
- the oxidation / adsorption and regeneration stages can be carried out in the same reactor or simultaneously in reactors arranged in parallel and operating alternately for one or other of the stages in a fixed bed, or in at least two moving bed reactors connected to each other by the catalytic bed, one being dedicated to oxidation / adsorption, the other to regeneration.
- the first reactor containing a fixed bed of catalyst receives the flows of hydrocarbons and oxidant and the second receives, for the regeneration of the catalyst, liquid effluents, for example a washing solvent, or oxidizing gaseous effluents , like air or an air / N 2 mixture, the temperature of the catalytic bed being raised.
- liquid effluents for example a washing solvent, or oxidizing gaseous effluents , like air or an air / N 2 mixture, the temperature of the catalytic bed being raised.
- the hydrocarbons are brought into the first oxidation reactor, the catalyst being gradually pushed to the second reactor, where it is regenerated before being returned in the oxidation / adsorption reactor.
