1. A process for the preparation of a feedstock for a hydroprocessing unit, wherein said feedstock is based on crude oil containing asphaltenes, said process comprising the steps of: mixing said crude oil with a solvent, wherein said solvent includes at least one of steam cracker cracked distillate
1. A process for the preparation of a feedstock for a hydroprocessing unit, wherein said feedstock is based on crude oil containing asphaltenes, said process comprising the steps of: mixing said crude oil with a solvent, wherein said solvent includes at least one of steam cracker cracked distillate (CD), steam cracker carbon black oil (CBO), low asphaltenes containing crude oil residue having a boiling point above 300° C. deg C. and aromatic rich hydrocarbons streams, wherein a mixing ratio of said solvent to said crude oil is such that no aggregation of asphaltenes in said combined mixture of solvent and crude oil takes place under mixing conditions; andfeeding said combined mixture of solvent and crude oil to one or more hydroprocessing units, wherein said combined mixture of solvent and crude oil comprises 25 wt. % or more of cracked distillate, based on the total weight of the feed blend. 2. A process for the preparation of a feedstock for a hydroprocessing unit, wherein said feedstock is based on crude oil containing asphaltenes, said process comprising the steps of: mixing said crude oil with a solvent, wherein said solvent includes at least one of steam cracker cracked distillate (CD), steam cracker carbon black oil (CBO), low asphaltenes containing crude oil residue having a boiling point above 300° C. deg C. and aromatic rich hydrocarbons streams, wherein a mixing ratio of said solvent to said crude oil is such that no aggregation of asphaltenes in said combined mixture of solvent and crude oil takes place under mixing conditions; andfeeding said combined mixture of solvent and crude oil to one or more hydroprocessing units, wherein said combined mixture of solvent and crude oil comprises a maximum of 55 wt. % of the higher asphaltenes containing crude stream in combination with the lower asphaltenes containing crude oils and aromatic streams. 3. The process according to claim 1, wherein said combined mixture of solvent and crude oil prior to entering the one or more hydroprocessing units, or its feed heaters, has an S value, measured as per ASTMD7157-12, of greater than 1. 4. The process according to claim 1, wherein said crude oil is a bottom stream from a vacuum distillation unit. 5. The process according to claim 1, further comprising deasphalting said crude oil, and separating the crude oil thus deasphalted in a stream having a low content of asphaltenes and a stream having a high content of asphaltenes, wherein said stream having a high content of asphaltenes is mixed with said solvent. 6. The process according to claim 1, wherein said one or more hydroprocessing units are chosen from the group of a resid hydrocracking unit and a coking unit. 7. The process according to claim 2, wherein said combined mixture of solvent and crude oil prior to entering the one or more hydroprocessing units, or its feed heaters, has an S value, measured as per ASTMD7157-12, of greater than 1. 8. The process according to claim 2, wherein said crude oil is a bottom stream from a vacuum distillation unit. 9. The process according to claim 2, further comprising deasphalting said crude oil, and separating the crude oil thus deasphalted in a stream having a low content of asphaltenes and a stream having a high content of asphaltenes, wherein said stream having a high content of asphaltenes is mixed with said solvent. 10. The process according to claim 2, wherein said one or more hydroprocessing units are chosen from the group of a resid hydrocracking unit and a coking unit. 11. The process according to claim 1, wherein said combined mixture of solvent and crude oil comprises more than 25 wt. % of low asphaltenes containing crude oil, atmospheric or vacuum residue, based on the total weight of the feed blend. 12. The process according to claim 2, wherein said combined mixture of solvent and crude oil comprises more than 25 wt. % of low asphaltenes containing crude oil, atmospheric or vacuum residue, based on the total weight of the feed blend. 13. The process according to claim 4, wherein said combined mixture of solvent and crude oil prior to entering the one or more hydroprocessing units, or its feed heaters, has an S value, measured as per ASTMD7157-12, of greater than 1. 14. The process according to claim 5, wherein said crude oil is a bottom stream from a crude oil distillation unit (CDU). 15. The process according to claim 8, further comprising deasphalting said crude oil, and separating the crude oil thus deasphalted in a stream having a low content of asphaltenes and a stream having a high content of asphaltenes, wherein said stream having a high content of asphaltenes is mixed with said solvent. 16. The process according to claim 3, wherein said one or more hydroprocessing units are chosen from the group of a resid hydrocracking unit and a coking unit. 17. The process according to claim 9, wherein said crude oil is a bottom stream from a vacuum distillation unit (VDU). 18. The process according to claim 17, wherein said combined mixture of solvent and crude oil comprises more than 25 wt. % of low asphaltenes containing crude oil, atmospheric or vacuum residue, based on the total weight of the feed blend.
