Abstract (en)
[origin: EP0816473A1] Non-carcinogenic bright stock extracts and/or deasphalted oils from reduced hydrocarbon feedstocks. Such non-carcinogenic bright stock extracts and/or deasphalted oils is accomplished by establishing a functional relationship between mutagenicity index and a distillation characteristic of said product stream, which when achieved, results in the product having a mutagenicity index of less than 1.0. Process conditions are established so that a product stream achieving the desired distillation parameter can be produced. Non-carcinogenic bright stock extracts and/or deasphalted oils are then processed utilising the conditions so established.
