Abstract:
1. A process for producing oils having an improved pour point and viscosity index from a hydrocarbon feed, said process comprising the following steps in succession: (a) converting the feed with simultaneous hydroisomerisation of at least a portion of the n-paraffins of the feed, said feed having a sulphur content of less than 1000 ppm by weight, a nitrogen content of less than 200 ppm by weight, a metals content of less than 50 ppm by weight, an oxygen content of at most 0.2% by weight, said step being carried out at a temperature of 200-500° C., at a pressure of 2-25 MPa, with a space velocity of 0.1-10 h (b) catalytic dewaxing of at least a portion of the effluent from step a), carried out at a temperature of 200-500° C., at a pressure of 1-25 MPa, with an hourly space velocity of 0.05-50 h
