Definitions

  • This invention is concerned with producing a high grade reduced crude having lowered metals and Conradson carbon values from a poor grade of reduced crude having extremely high metals and Conradson carbon values.
  • this invention describes a sorbent material that can be utilized for the reduction of these metal and Conradson carbon values that exhibits a low catalytic cracking activity value.
  • a further embodiment of this invention is the inclusion of a metal additive as a select metal, organo metallic, its oxide or salt into the sorbent material during manufacture or during the processing cycle to immobilize the sodium vanadate, vanadium pentoxide deposited on the sorbent during processing.
  • This invention also describes a regeneration process to immobilize the vanadium pentoxide by maintaining the metal in a reduced or lower oxidation state to prevent vanadium mobility.
  • This invention also provides a method for the processing of reduced crudes high in metals and Conradson carbon to provide a feedstock for a reduced crude conversion process or for typical fluid catalytic cracking processes.
  • H-Oil's Dynacracking Phillips Heavy Oil Cracking (HOC): H-Oil, Gulf, Union-UOP processes, and Aurabon hydrotreating processes; and solvent deasphalting.
  • HOC Phillips Heavy Oil Cracking
  • FCC solvent deasphalting
  • Conradson carbon is to increase that portion of the feedstock converted to carbon deposited on the catalyst.
  • Conradson carbon is to increase that portion of the feedstock converted to carbon deposited on the catalyst.
  • contaminant coke from metal deposits
  • catalytic coke acid site cracking
  • entrained hydrocarbons pore structure adsorption-poor stripping
  • Conradson carbon Conradson carbon
  • coke production based on feed is the summation of three of the four kinds mentioned above plus exceedingly higher Conradson carbon values.
  • coke production when processing reduced crude is normally and most generally around 4-5wt% plus the Conradson carbon value of the feedstock.
  • two other types of coke former processes or mechanisms may be manifested present in reduced crude processing in addition to the four exhibited by VGO. They are adsorbed and absorbed high boiling hydrocarbons not removed by normal efficient stripping due to their high boiling points, and carbon associated with high molecular weight nitrogen compounds adsorbed on the catalyst's acid sites.
  • the spent-coked catalyst is brought back to new equilibrium activity by burning off the deactivating coke in a regeneration zone in the presence of air and recycled back to the reaction zone.
  • the heat generated during regeneration is removed by the catalyst and carried to the reaction zone for vaporization of the feed and to supply the heat for the cracking reaction.
  • the temperature in the regenerator is limited because of metallurgy limitations and the thermal-steam stability of the catalyst.
  • the thermal-steam stability of the zeolite containing catalyst is determined by the temperature and steam partial pressure at which the zeolite irreversibly loses its crystalline structure to form low activity amorphous material. Steam, generated by the burning of adsorbed carbonaceous material containing a high hydrogen content is highly detrimental.
  • This carbonaceous material is principally hydrogen containing carbonaceous product as previously described plus high boiling adsorbed hydrocarbons with boiling points as high as 815.5°C-926.7°C (1500-1700°F) that have a high hydrogen content, high boiling nitrogen containing hydrocarbons and porphyrins-asphaltenes.
  • the metal containing fractions of reduced crude contain Ni-V-Fe-Cu, present as porphyrins and asphaltenes. These metal containing hydrocarbons are deposited on the catalyst during processing, are cracked in the riser to deposit the metal or carried over by the spent catalyst as the metallo-porphyrins or asphaltenes and converted to the oxide during regeneration.
  • the adverse effects of these metals are to decrease the acidity of the zeolite thereby reducing catalytic cracking activity, thus, enhancing non-selective cracking and dehydrogenation to produce light gases such as hydrogen, methane and ethane and more importantly, increase coke production all of which affects selectivity and yield.
  • the increased production of light gases affects the economic yield and selectivity structure of the process and puts an increased demand on compressor capacity.
  • the increase in coke production also adversely affects catalyst activity-selectivity and leads to increased regenerator air demand and compressor capacity, and elevated regenerator temperatures.
  • a reduced crude or crude oil having a high metal and Conradson carbon value is contacted in an RCC type regenerator-reactor system with an inert solid sorbent of low surface area at temperatures above about 482.2°C (900°F). Residence time in the riser is below 5 seconds, preferably 0.5-2 seconds.
  • the particle size of the inert solid sorbent is approximately 20-150 microns in size to ensure adequate fluidization properties.
  • the reduced crude-crude oil is introduced at a temperature below thermal cracking at the bottom of the riser and contacts the inert solid sorbent at a temperature of 621.1°C-760°C (1150-1400°F) and exits the riser at a temperature in the reactor vessel of approximately 482.2°C-621.1°C (900-1050°F).
  • water, steam, naphtha, flue gas, etc. may be introduced to aid in vaporization and act as a lift gas to control residence time.
  • the sorbent is rapidly separated from the hydrocarbon vapors at the top of the riser by employing the vented riser concept developed by Ashland Oil, Inc., see U.S. Patent No. 4,066,533.
  • the metal and Conradson carbon compounds are deposited on the sorbent.
  • the spent sorbent is deposited as a dense bed at the bottom of the reactor vessel, transferred to a stripper and then to the regeneration zone.
  • the spent sorbent is contacted with an oxygen containing gas to remove the carbonaceous material through combustion to carbon oxides to yield a regenerated sorbent containing 0.05-0.2 wt% carbon.
  • the regenerated sorbent is then recycled to the bottom of the riser to meet additional high metal and Conradson carbon containing feed to repeat the cycle.
  • vanadium deposited on the sorbent is converted to vanadium oxides, in particular, vanadium pentoxide.
  • the melting point of vanadium pentoxide is much lower than temperatures encountered in the regeneration zone.
  • any momentary stoppage of flow such as occurs in a cyclone dipleg, permits coalescence of two or more particles and ultimately inhibition of flow and loss of cyclone operation.
  • vanadium pentoxide solidifies, thus causing solid plugs of microspheres bound together by the vanadium pentoxide cement. This cause and effect of vanadium pentoxide can be overcome by two methods.
  • the process of this invention and sorbent are not limited to a fluidized bed operation with microspherical particles of 10-200 microns in size, but can include moving bed operations employing microspherical particles of greater than 200 microns in size.
  • the select sorbents of this invention will include solids of low catalytic activity, such as spent catalyst, clays, bentonite, kaolin, montmorillonite, smectites, and other 2-layered lamellar silicates, mullite, pumice, silica, laterite, etc.
  • the surface area of these sorbents would preferably be below 25 m 2 /g, have a pore volume of approximately 0.2 cc/g or greater and a micro-activity value as measured by the ASTM Test Method No. D3907-80 of below 20.
  • the metal additive is a water soluble compound which can be the oxide or one of its salts such as the nitrate, halide, sulfate, carbonate, etc. This mixture is spray dried to yield the finished promoted sorbent as a microspherical particle of 10-200 microns in size with the active promoter deposited within the pores and/or the outer surface of the sorbent particle.
  • the concentration of vanadia on the spent sorbent is targeted to be approximately 2-5 wt% of final particle weight, the concentration of metal additive will be in the range of 1-6 wt% to maintain at least a one to one atomic ratio of vanadium to metal additive at all times.
  • the sorbent can also be impregnated with these metal additives after spray drying, employing techniques well known in the art or combined with the clay as a gel so as to serve also as a binder and pore volume extender in the spray dried product.
  • the metal additives of this invention will form compounds or complexes with vanadia that have higher melting points or serve to immobilize the migration of vanadia at the temperatures encountered in the regeneration zone.
  • the targeted one to one molar ratio is chosen as more or less a practical objective. Initially, in those cases where the additive is included in the preparation the metal additive will be at a concentration far exceeding targeted ratios. However, as vanadia content increases, this ratio gradually decreases as vanadia is deposited on the sorbent. The melting point and migration behaviour of the vanadia-metal oxide compound or complex decreases, as vanadia increases, usually approaching a eutectic having a melting point even lower than vanadium pentoxide. For this reason, the additive is kept high in the virgin sorbent or is added in approximately stoichiometric proportions with vanadium in the feedstock.
  • this approach also relates to the lower valences of vanadium, and further in processing a sulfur containing feed and regeneration in the presence of an oxygen containing gas there will likely exist vanadium sulfides, sulfites, sulfates, and which will create still other mixtures containing mixed oxides and sulfides, sulfates, etc.
  • the metal additive is not incorporated in the initial sorbent preparation or added to the sorbent during manufacture then it can be added during the processing cycle at any point of sorbent travel in the processing unit. This would include but not be limited to addition of an aqueous solution of the inorganic metal salt or hydrocarbon solution of metallo-organic compounds at the riser bottom 17, along the riser length 4, the dense bed 9 in reactor vessel 5, stripper 10 and stripper 15, regenerator inlet 14, regenerator dense bed 12, or regenerated sorbent standpipe 16.
  • the vanadium deposited on the sorbent is immobilized through select regeneration conditions. Initially, the vanadium is deposited on the sorbent and in the regeneration zone under typical conditions is converted to vanadium pentoxide during coke combustion. The sorbent containing vanadium pentoxide is transferred to the riser and under the reducing conditions resulting from contacting vaporized feed will undergo reduction to lower oxidation states. Since reduced vanadium oxide is covered by the heavy coke deposition it will be protected against oxidation in the regeneration zone. Under controlled conditions of combustion the coke level on the sorbent will be reduced to 0.05-0.2 wt% on sorbent weight, preferably 0.1-0.2 wt%.
  • Operation of the regenerator in a semi-reducing condition can also be utilized to maintain vanadium in a lower valence state.
  • This type of operation establishes a condition wherein all the oxygen has been consumed and that none is left to further reduce the coke level or oxidize the vanadium to a higher oxidation level.
  • vanadium pentoxide in the riser yields vanadium oxide (V..-4, V0 2 ) and vanadium trioxide (V+3, V 2 0 3 ) which have much higher melting points, such as 982.2°C (1800°F) or higher.
  • V..-4, V0 2 vanadium oxide
  • V+3, V 2 0 3 vanadium trioxide
  • the lower vanadium oxidation states are maintained so as to avoid the flow and fusion problems which otherwise would occur.
  • the selective sorbent of this invention with or without the additive metal promoter is charged to a fluidized Metal Removal System as outlined in Figure 1.
  • Sorbent particle circulation and operating parameters are maintained by methods well known to those skilled in the art.
  • the equilibrium sorbent at temperatures of 593.3°C-760°C (1100-1400°F) contacts the reduced crude containing high metals and Conradson carbon values at riser wye 17.
  • the reduced crude can be accompanied by steam and/or naphtha, or dry gases or flue gas injected at point 2, water and/or naphtha injected at point 3 to aid in vaporization, sorbent fluidization and controlling contact time in riser 4.
  • the sorbent and vaporous hydrocarbons travel up riser 4 at a contact time of 0.1-5 seconds, preferably 0.5-2 seconds.
  • the sorbent and vaporous hydrocarbons are separated in vented riser outlet 6 at a final reaction temperature of 482.2°C-621.1°C (900-1050°F).
  • the vaporous hydrocarbons are transferred to cyclone 7 where any entrained sorbent fines are separated and the hydrocarbon vapors are sent to the fractionator via transfer line 8.
  • the spent sorbent drops to the bottom of vessel 5 to form a dense bed 9.
  • the spent sorbent is then transferred to stripper 10 for removal of any entrained hydrocarbon vapors and then to regenerator vessel 11 to form dense bed 12.
  • An oxygen containing gas such as air is admitted to the bottom of dense bed 12 in vessel 11 to combust the coke to carbon oxides.
  • the resulting flue gas is processed through cyclones and exits from regenerator vessel 11 via line 13.
  • the regenerated sorbent is transferred to stripper 15 to remove any entrained combustion gases and then transferred to riser wye 17 via line 16 to repeat the cycle.
  • Addition points 18 and 19 can be utilized to add a metal additive promoted sorbent.
  • the metal additive as an aqueous solution or an organo-metallic compound in aqueous or hydrocarbon solvent can be added at addition points 18 and 19 as well as at addition points 2 and 3 on feed line 1, addition point 20 in riser 4, addition point 21 to the bottom of vessel 5 into dense bed 9.
  • the addition of the metal additive is not limited to these locations but can be practiced at any point along the reduced crude-sorbent processing cycle.
  • Sorbent and reduced crude feedstock are processed in a manner similar to that described previously.
  • the spent sorbent after stripping in stripper 10 is transferred to regenerator vessel 11.
  • the amount of oxygen containing gases admitted through line 14 into dense bed 12 is sufficient to only regenerate a large portion of the coke deposited on the sorbent.
  • the regenerated sorbent exiting regenerator vessel 11 to stripper 15 contains 0.05-0.2 wt% coke, preferably 0.1-0.2 wt%.
  • This amount of coke on regenerated sorbent is sufficient to help ensure that the vanadium pentoxide reduced in the riser to lower vanadium oxides (monoxide, trioxide) will remain in these reduced states.
  • the small amount of coke remaining on the sorbent ensures that vanadium in the lower oxidation state is not re-oxidized to the higher +5 state.
  • the regenerator vessel as illustrated in Figure 1 is a simple one zone-dense bed type.
  • the regenerator section is not limited to this example but can exist of two or more zones, stacked or side-by-side arrangement, with internal and/or external circulation transfer lines from zone to zone.
  • a sorbent clay spray dried to yield microspherical particles in 20-150 micron size, had vanadia deposited upon it in varying concentrations.
  • the sorbent, free of vanadia, and those containing varying vanadia concentrations were placed in individual ceramic crucibles and calcined at 760.0°C (1400°F) in air for two hours. At the end of this time the period the crucibles were withdrawn from the muffle furnace and cooled to room temperature. The surface texture and flow characteristics of these samples were noted and the results are reported in Table I.
  • the sorbent free of vanadia does not form any crust or clumps or fused particles at temperatures encountered in the regenerator section of the process described in this invention. At vanadia concentrations above 5,000 ppm the absorbent begins to clump and bind badly and does not flow at all.
  • An extension of the clumping test is the use of a ceramic-alumina crucible to determine the end product of vanadia reacting with the metal additives. If vanadia does not react with the metal additive or only a small amount of compound formation occurs, then the vanadia will diffuse through and over the porous alumina walls and deposit as a yellowish to orange deposit on the outside walls of the crucible. On the other hand, when compound formation occurs, there is little or no vanadia deposits on the outside crucible wall. Two series of tests were performed, in the first series shown in Table 2, 1/1 mixture by weight of vanadia pentoxide and the metal additive was placed in the crucible and heated to 815.6°C(1500°F) in air for 12 hours. Compound formation or vanadia diffusion was noted.
