Definitions

  • the present invention relates to demetallation of petroleum crude oil, and, more particular, to the removal of metals in the oil by contact with a catalyst having Ni, Mo and/or CoMo supported on a zeolitic carrier.
  • Petroleum crudes are known to contain metals such as Ni, V, Fe, Co, etc. in ppm levels. To a large extent, these components are associated with the heaviest parts of the resid, i.e. the part of the resid with the highest boiling points. This means that these components are concentrated in the bottom fractions often designated atm. or vacuum residuum.
  • Heavy oil fractions containing metal compounds are predominantly those with an atmospheric boiling point above 350°C.
  • the heavy oil fractions will typically contain 50-500 ppm of mainly Ni and V.
  • Those trace metals are normally removed in a fixed bed catalytic process, where the residual oil comes into contact with a demetallation catalyst at high temperature, typically at 300-450°C at a high H 2 pressure, such as 20-200 bars and at a space velocity in the range of 0.25-4 h -1 .
  • the metals presented in the feedstock will react and accumulate on the catalyst surface.
  • demetallation catalysts consist of Ni and Mo or CoMo supported on alumina. It has now been found that metals are removed from petroleum crude oil with a high efficiency in a demetallation process, when employing a demetallation catalyst supported on a carrier comprising zeolitic material.
  • this invention provides a process for the demetallation of petroleum crude oil by contacting the oil together with hydrogen with a catalyst having at least one metal or compound thereof of Group VIII and/or Group VI of the Periodic Table as active material supported on a carrier, wherein the carrier comprises a zeolite with a SiO 2 /Al 2 O 3 ratio of at least 5 and a unit cell size of between 24.30 and 24.60.
  • Preferred metals for use in the process are Ni, Mo, CoMo or mixtures thereof.
  • the catalyst may be prepared by any method being conventional in the art and including impregnation of the calcined carrier with an aqueous solution of salts of the active metal or metals, drying the impregnated carrier and finally calcinating the carrier to obtain the active catalyst.
  • the catalyst is arranged as fixed bed in a demetallation reactor and crude oil feedstock passed together with hydrogen in a ratio of typically 200-2000 Nl/l through the catalyst bed.
  • the bed temperature is maintained at elevated temperature and pressure of usually 350-450 o C and 120-170 atm.
  • the metal content in the feedstock is reduced to few ppm.
  • the calcined carrier was impregnated by pore volume filling with an impregnation solution containing 18.3 g of Co(NO 3 ) 2 ⁇ 6H 2 O, 15 g of ammonium dimolybdate and distilled water up to 82 ml. After impregnation, the catalyst was dried at room temperature for 16 hrs. The dried and impregnated catalyst was finally calcined at 500°C for 2 hours.
  • the catalyst thus prepared is designated A.
  • a catalyst carrier was prepared by mixing 30 g of dried HY Zeolite CBV 500 with 62 g of Versal 300 alumina and 126 g of alumina gel.
  • the catalyst carrier was dried, calcined, impregnated and decomposed at the same conditions as described under Example 1.
  • the catalyst thus prepared is designated B.
  • the catalysts of Examples 1-3 were tested in a fixed bed with a small protective layer of commercial demetallation catalysts, in order to control the amounts of metals that will deposit on the catalyst of the invention.
  • the catalyst bed lay-out used in the test is summarized in Table 3.
  • Table 3 Catalyst Bed Lay-Out Vol.-% 1) Loading 1 Loading 2 Loading 3 Loading 4 10 TK-711 1/32"C 25 TK-751 1/32"C 60
  • Fig. 1-3 show the catalyst activity of catalyst loadings 1-3 in comparison with the conventional Al 2 O 3 based system.
  • Fig. 1-3 are Arrhenius plots giving the first order rate constants for demetallation.
  • Fig. 1-3 the activity obtained on a conventional catalyst system is given as solid lines.
  • Each of the catalysts of this invention shows an improved activity for demetallation as apparent from the data in Fig. 1-3.
  • the level of improvement in relation to known catalysts are in the order of 20-40%, which for the test conditions and feeds tested results in a substantially completely demetallized hydrocarbon product.
