초록 ▼

A method of hydroprocessing is performed wherein non-petroleum feedstocks, such as those containing from about 10% or more olefinic compounds or heteroatom contaminants by weight, are treated in a first reaction zone to provide reaction products. The process involves introducing the feedstock along with diluents or a recycle and hydrogen in a first reaction zone and allowing the feed and hydrogen to react in a liquid phase within the first reaction zone to produce reaction products. The reaction products are cooled and/or water is removed from the reaction products. At least a portion of the cooled and/or separated reaction product are introduced as a feed along with hydrogen into a second reaction zone containing a hydroprocessing catalyst. The feed and hydrogen are allowed to react in a liquid phase within the second reaction zone to produce a second-reaction-zone reaction product.

1. A method of hydroprocessing comprising: (a) introducing a non-petroleum feed containing from about 10% or more oxygen by weight to be treated along with a diluent and hydrogen into a first reaction zone containing a hydroprocessing catalyst, the amount of diluent combined with the non-petroleum feed being selected to (A) dissolve a preselected amount of hydrogen in the combined non-petroleum/diluent feed; (B) maintain the temperature within the reactor below a preselected temperature; and/or (C) adjust the capacity of the liquid phase to dissolve or carry water and hydrogen;(b) allowing the feed and hydrogen to react in a liquid phase within the first reaction zone to produce reaction products, at least one of the reaction products being water;(c) removing the reaction products from the first reaction zone;(d) separating water from the removed reaction products as an aqueous phase to provide a separated reaction product that is free from the separated water; and(e) introducing at least a portion of the separated reaction product as a feed along with hydrogen into a second reaction zone containing a hydroprocessing catalyst; and(f) allowing the separated reaction product feed and hydrogen to react in a liquid phase within the second reaction zone to produce a second-reaction-zone reaction product. 2. The method of claim 1, wherein: the diluent is provided by at least one of (1) a further portion of the separated reaction product of step (d) and (2) at least a portion of the second-reaction-zone reaction product of step (f). 3. The method of claim 1, wherein: the separated reaction product is substantially water-free. 4. The method of claim 1, wherein: water makes up at least 10% by weight of the total reaction products. 5. The method of claim 1, wherein: water makes up at least 20% by weight of the total reaction products. 6. The method of claim 1, wherein: water makes up at least 30% by weight of the total reaction products. 7. The method of claim 1, wherein: the non-petroleum feed is comprised of pyrolysis oils. 8. The method of claim 7, wherein: the pyrolysis oils are derived from at least one of cellulosic biomass materials and coal. 9. The method of claim 1, wherein: the non-petroleum feed to be treated is comprised of at least 20% by weight oxygen. 10. The method of claim 1, wherein: the non-petroleum feed is introduced in the first reaction zone under conditions so that substantially all the feed and hydrogen are in a continuous liquid phase within the first reaction zone. 11. The method of claim 1, wherein: the removed reaction products of step (c) are cooled prior to separating water according to (d). 12. The method of claim 1, wherein: the first and second reaction zones are reactors and wherein each reactor contains greater than 10% hydrogen gas by total volume of the reactor. 13. The method of claim 1, wherein: no excess hydrogen gas is vented from the first and second reaction zones to facilitate controlling quantities of liquids within the reaction zones. 14. A method of hydroprocessing comprising: (a) introducing a non-petroleum feed containing from about 10% or more oxygen by weight to be treated along with a diluent and hydrogen into a first reaction zone containing a hydroprocessing catalyst, the amount of diluent combined with the non-petroleum feed being selected to (A) dissolve a preselected amount of hydrogen in the combined non-petroleum/diluent feed; (B) maintain the temperature within the reactor below a preselected temperature; and/or (C) adjust the capacity of the liquid phase to dissolve or carry water;(b) allowing the feed and hydrogen to react in a liquid phase within the first reaction zone to produce reaction products, at least one of the reaction products being water;(c) removing the reaction products from the first reaction zone;(d) cooling the removed reaction products;(e) separating water from the removed reaction products to provide a separated reaction product that is free from the separated water;(f) introducing at least a portion of the separated reaction product as a feed along with hydrogen into a second reaction zone containing a hydroprocessing catalyst;(g) allowing the separated reaction products and hydrogen to react in a liquid phase within the second reaction zone to produce reaction products;(h) removing the reaction products produced in (g) from the second reaction zone;(i) cooling the removed reaction products from (h); and(j) separating any gas phase and any liquid water phase from the cooled reaction products from (i) to form a separated reaction product that is free from any separated liquid water to provided a separated liquid reaction product. 15. The method of claim 14, wherein: the diluent is provided by at least one of (1) a further portion of the separated reaction product of step (e) and (2) at least a portion of the separated liquid reaction product of step (j). 16. The method of claim 14, wherein: the separated reaction products of steps (e) and (j) are substantially water-free. 17. The method of claim 14, wherein: water makes up at least 10% by weight of the total reaction products. 18. The method of claim 14, wherein: water makes up at least 20% by weight of the total reaction products. 19. The method of claim 14, wherein: water makes up at least 30% by weight of the total reaction products. 20. A method of hydroprocessing comprising: (a) introducing a non-petroleum feed to be treated containing from about 10% or more by total weight of feed of at least one of olefinic compounds and heteroatom contaminants along with a diluent and hydrogen into a first reaction zone containing a hydroprocessing catalyst, the amount of diluent combined with the non-petroleum feed being selected to (A) dissolve a preselected amount of hydrogen in the combined non-petroleum/diluent feed; (B) maintain the temperature within the reactor below a preselected temperature; and/or (C) adjust the capacity of the liquid phase to dissolve or carry water;(b) allowing the feed and hydrogen to react in a liquid phase within the first reaction zone to produce reaction products;(c) removing the reaction products from the first reaction zone;(d) cooling the removed reaction product;(e) introducing at least a portion of the cooled reaction product as a feed along with hydrogen into a second reaction zone containing a hydroprocessing catalyst; and(f) allowing the cooled reaction product and hydrogen to react in a liquid phase within the second reaction zone to produce a second-reaction-zone reaction product.
