Definitions
- the invention described here is part of this framework. It consists in hydrotreating charges from renewable sources and in particular in hydrogenating vegetable oils so as to obtain linear paraffins containing 6 to 25 carbon atoms. These paraffins are then sent to a steam cracking plant (or according to the Anglo-Saxon steam-cracking determination) sized as for the treatment of petroleum fractions but also able to convert these paraffins into ethylene and propylene and resulting polymers with significantly higher yields.
- the objective of the invention is therefore the production, with very high yields, of ethylene and propylene from a paraffin section resulting from the hydrotreatment of charges from renewable sources.
- U.S. Patent 4,620,050 discloses a process for the production of high purity ethylene or a mixture of ethylene / carbon monoxide directly usable by decomposition in the gas phase of certain ethyl esters of aliphatic carboxylic acids at a temperature of between 150 and 300 ° C. in the presence of a zeolitic catalyst.
- US Patent Application 2007/0015947 discloses a process for producing C2-C5 olefins from feeds from a renewable source comprising a first charge pretreatment step for removing contaminants such as alkali metals and a second step of cracking the purified feed in a fluidized catalytic cracking (FCC) zone.
- FCC fluidized catalytic cracking
- a method of treating a feedstock from a renewable source comprising the following steps: a) two-stage hydrotreatment wherein said first mild prehydrogenation treatment stage operates at a temperature of between 50 and 50.degree. 300 ° C., at a hydrogen partial pressure of between 0.1 and 10 MPa, and at a catalyst hourly space velocity of between 0.1 h -1 and 10 h -1, wherein said prehydrogenation catalyst comprising at least one noble metal of group VIII chosen from palladium and platinum or comprising at least one non-noble metal of group VIII and / or at least one metal of group VIB, the non-noble metal of group VIII being chosen from nickel and the cobalt and the group VIB metal being selected from molybdenum and tungsten, said prehydrogenation catalyst being a metal phase catalyst and wherein said second stage of the process It is carried out at a temperature of between 200 and 450 ° C., at a pressure of between 1 MPa and 10 MPa, at a catalyst hourly space velocity
- the feedstocks are derived from renewable sources, such as vegetable or animal oils and fats, or mixtures of such fillers, containing triglycerides and / or fatty acids and / or esters.
- vegetable oils they can be raw or refined, wholly or in part, and derived from the following plants: rapeseed, sunflower, soybean, palm, palm kernel, olive, coconut, this list not being limiting.
- fats there may be mentioned all animal fats such as bacon or fats consisting of residues from the food industry or from the food service industries.
- the charges thus defined contain triglyceride and / or fatty acid structures and their esters, whose fatty chains contain a number of carbon atoms of between 6 and 25.
- the hydrocarbons produced during the conversion of the feedstock are characterized by: a) a number of carbon atoms equal to that of the chains of the starting fatty acids, if the mechanism is a mechanism for hydrogenation of the carboxylic group into an alkyl group . b) A hydrocarbon chain containing one carbon atom less than the chains of the starting fatty acids, if the mechanism involved is a decarboxylation / decarbonylation.
- the mechanism a) has the advantage of offering a very good paraffin yield of carbon number equivalent to that of the starting fatty acid, but on the other hand has the disadvantage of causing a very significant hydrogen consumption. up to 3.6% wt hydrogen.
- Mechanism b) has the disadvantage of a slightly lower weight yield related to the reduction of a carbon atom in the chain, which for example passes from Cl 8 to C 17 for a rapeseed oil, but on the other hand allows to limit H2 consumption to only 1.6% wt.
- One of the advantages of the invention is to optimize the consumption of hydrogen in the hydrogenation mechanism according to a) while minimizing the decarboxylation / decarbonylation mechanism according to b).
- An object of the present invention is the preparation of steam cracker feeds making it possible to obtain a very high yield of ethylene and propylene and resulting polymers, and this from feedstock from renewable sources.
- feedstocks from renewable sources consist of all vegetable oils and animal fats, mainly containing triglycerides and fatty acids or esters, with hydrocarbonaceous fatty chains having a number of carbon atoms of between 6 and 25 carbon atoms.
- These oils may be palm, palm kernel, coconut, castor oil, cotton, peanut, flax and crambe oils and all oils derived for example from sunflower or rapeseed by genetic modification or hybridization. .
- Fried oils, various animal oils such as fish oils, tallow, lard can be used.
- the feedstock may undergo before step a) of the process according to the invention a pre-treatment or pre-refining step so as to eliminate, by appropriate treatment, contaminants such as metals, alkali, alkaline earth and phosphorus, for example on ion exchange resins.
- Suitable treatments may for example be heat and / or chemical treatments well known to those skilled in the art.
- step a) of hydrotreating feedstock from renewable sources is carried out in two stages.
- Step a) consists, advantageously, in a first treatment step consisting of a gentle prehydrogenation of at least 50% of the double bonds contained in the hydrocarbon chain of the fatty acids of said filler, preferably at least 80% double bonds, very preferably at least 90% of the double bonds and even more preferably at least 99% of the double bonds, followed by a second treatment stage consisting of hydrogenation of at least 50% of the ester functions contained in the hydrocarbon chain of the fatty acids of said filler, preferably at least 80% of the double bonds, very preferably at least 90% of the ester functions and even more preferably at least 99% of the ester functions.
- step a) consists of a first treatment step consisting of a gentle prehydrogenation of at least 50% of the double bonds contained in the hydrocarbon chain of the fatty acids of said feedstock. followed by a second treatment step consisting of a hydrogenation of at least 50% of the ester functions contained in the hydrocarbon chain of the fatty acids of said feedstock.
- step a) consists of a first treatment step consisting of a gentle prehydrogenation of at least 90% of the double bonds contained in the hydrocarbon chain of the fatty acids of said charge, followed by a second treatment step consisting of a hydrogenation of at least 90% of the ester functions contained in the hydrocarbon chain of the fatty acids of said charge.
- step a) consists of a first treatment step consisting of a gentle prehydrogenation of at least 99% of the double bonds contained in the hydrocarbon chain of the fatty acids of said charge, followed by a second treatment step consisting of a hydrogenation of at least 99% of the ester functions contained in the hydrocarbon chain of fatty acids of said charge.
- the double bonds of the hydrocarbon chains can be determined by several analytical methods:
- the measurement of the iodine index consists in measuring the amount of diiodine (I 2 ) capable of being fixed on the unsaturations of the hydrocarbon chains. expressed in mg of I 2 fixed on 100 g of product.
- the iodine value is for example 90 on oleic acid, 181 for linoleic acid and 274 for linolenic acid.
- the iodine number is measured in the vegetable oil methyl esters (VOME), according to the standardized method EN 14111.
- Other standard methods can also be cited as ASTM D1959 and ASTM D5554.
- the bromine number is applicable for contents of less than 1000 mg / 100 g of product, according to the ASTM D2710 standard.
- the number of bromine concerns potentiometric assays for contents greater than 1 g / 100 g of product, according to the ASTM D1159 standard.
- ester functions is demonstrated according to an infra-red spectrometry method.
