- the final catalyst contains 60% by weight of zeolite Y.
- Example 4 Analyzes of the Catalysts The two catalysts A and C containing only about 16% of zeolite were analyzed so as to demonstrate the presence or absence of niobium in the zeolite.
- the first method used is transmission electron microscopy equipped with an X energy dispersion spectrometer allowing the identification and quantification of the elements present in the crystals of the zeolite.
- JEOL 2010R URP equipped with an X TRACOR energy dispersion spectrometer itself equipped with a Z-MAX30 detector.
- the catalyst extrudates are finely ground in a mortar.
- the powder is mixed in resin to make ultra-thin cuts of thickness 700 A for the two catalysts.
- the cuts produced are collected on a Cu grid covered with a membrane C with holes serving as a support for the preparation. These preparations are dried under an IR lamp before being introduced into the transmission electron microscope where they will be subjected to a primary vacuum for a few minutes and then to a secondary vacuum during the entire observation.
- the electron microscope makes it possible to perfectly identify the crystals of zeolite with a size of about 0.4 micron dispersed in the alumina matrix. We then proceed to a certain number of local analyzes (from 15 to 20) carried out on various zones of matrix and on various crystals of zeolites with a probe beam of 0.1 micron in diameter. Quantitative signal processing provides the relative concentration in atomic% of the elements (excluding oxygen).
- Table 1 summarizes the results obtained for samples A and C described in the examples above.
- the catalyst A contains crystals of zeolite Y without molybdenum and without niobium.
- the amount of Ni detected is due to the imprecision of the measurement.
- this analysis technique makes it possible to detect without ambiguity the presence of niobium and the absence of molybdenum in the crystals of zeolite Y.
- the second technique used is the electronic microprobe. Some extrudates are coated with resin and then polished to their diameter and metallized with carbon. The sample is introduced into a JXM 880 apparatus in order to analyze the local composition of Al, Si, Mo, Nb and Ni in different pumps.
- niobium in the zeolite Y in the case of sample C, the following calculations are carried out. For each analysis point the concentration of oxide of Al, Si, Mo, Nb and Ni is measured From the concentration in Al and Si oxide and the atomic ratio of the zeolite, the mass ratio AI 2 O 3 / (Zeolite Y + AI2O3) is deduced at each point. We can then draw up a diagram linking the niobium concentration measured as a function of the mass ratio AI 2 O 3 / (Zeolite Y + AI2O3) For catalyst C, the measuring heads containing no zeolite and therefore for which AI2O3 / (Zeolite Y + must not contain niobium.
- the catalysts are used under the conditions of hydrocracking at moderate pressure on an oil charge, the main characteristics of which are as follows:
- the catalytic test unit includes two reactors in a fixed bed, with upward flow of charge ("up-flow"). 40 ml of catalyst are introduced into each of the reactors.
- the catalyst for the first hydrotreatment stage HTH548 sold by the company is introduced. Procatalvse comprising an element of group VI and an element of group VIII deposited on an alum.
- the hydrocracking catalyst (A, B, C or D) is introduced.
- the two catalysts undergo an rn-situ sulfurization step before reaction. Note that any rn-situ or ex-situ sulfurization method is suitable.
- the charge described above can be transformed.
- the total pressure is 8.5 MPa
- the hydrogen flow rate is 500 liters of gaseous hydrogen per liter of charge injected
- the hourly volume speed is 0.8 h " l.
- the two reactors operate at the same temperature .
- the catalytic performances are expressed by the gross conversion at 400 ° C (CB), by the gross selectivity (SB) and by the conversions in hydrodesulfurization (HDS) and in hydrodenitrogenation (HDN) These catalytic performances are measured on the catalyst after a stabilization period, generally at least 48 hours, has been observed.
- catalyst C Comparison of catalyst C with catalyst A containing the same amount of zeolite Y, oxide matrix, hydrogenating element and phosphorus, shows that the presence of a metal of group VB contained in the porous network of the zeolite gives more a better level of conversion of the 380 ° C fraction than catalyst A which does not contain any.
- the selectivity is of the same level while the activity in HDS and HDN is slightly increased.
- catalysts B and D containing a large amount of zeolite there is a very marked improvement in the conversion, the selectivity and the HDS and HDN activities when the metal of group VB is present in the porous network of the zeolite.
- catalysts C and D containing niobium in the porous network have the advantage of giving better performance in hydrotreatment (hydrodesulfurization and hydrodenitrogenation).
- Example 4 Comparison of the hydrocracking catalysts of a distill t under vacuum at higher pressure.
- the catalysts are used under the conditions of hydrocracking at high pressure (12 MPa) on an oil charge, the main characteristics of which are as follows: initial pump 277 ° C. pump 10% 381 ° C. pump 50% 482 ° C pump 90% 531 ° C pump final 545 ° C flow pump + 36 ° C density (20/4) 0.919
- the catalytic test unit comprises two reactors in fixed ht, with upward flow of the charge ("up-flow"). 40 ml of catalyst are introduced into each of the reactors.
- the catalyst "1" of the first hydrotreatment stage HR360 sold by the company Procatalyse is introduced, comprising an element from group VI and an element from group VIII deposited on alumina.
- the second reactor the one in which the charge passes last, the second stage catalyst “2” is introduced, that is to say the hydroconversion catalyst.
- the two catalysts undergo an rn-situ sulfurization step before reaction. Note that any m-situ or ex-situ sulfurization method is suitable.
- the total pressure is 12 MPa
- the hydrogen flow rate is 1000 liters of gaseous hydrogen per liter of charge injected
- the overall hourly volume speed is 0.9 h ⁇
- the temperature of the first reactor is 390 ° C.
- the catalytic performances are expressed by the temperature which makes it possible to reach a gross conversion level of 70% and by the gross selectivity. These catalytic performances are measured on the catalyst after a stabilization period, generally at least 48 hours, has been observed.
- the gross selectivity SB is taken equal to: minus
- reaction temperature of the second reactor containing the hydroconversion catalyst (A, B, C or D) is fixed so as to reach a gross conversion CB equal to 70% by weight.
- catalyst B containing a large amount of zeolite Y relative to catalyst A shows that by increasing the amount of zeolite the activity of the catalyst greatly increased by the temperature level required to obtain 70% conversion of the charge but leads to a very significant loss of selectivity.
- the presence of an element of group VB inside the porous network of the zeolite obtained with sample C and D shows that the very good level of selectivity of catalyst A is maintained.
- Sample D has on the other hand much better activity like sample B due to the presence of a high zeolite content. Adding a VB group metal at the sem of the porous network of the zeolite is therefore particularly advantageous for obtaining hydrocracking catalysts which are very active and very selective in middle distillates.
