【発明の名称】非発癌性ブライトストック抽出物、脱れき油及びこれらの製造方法
Document Type and Number:
Japanese Patent JP3229614
Kind Code:
B2
Abstract:
Non-carcinogenic asphalts and asphalt blending stocks are produced from reduced hydrocarbon feedstocks. Such non-carcinogenic products are produced by establishing a functional relationship between mutagenicity index and a physical property correlative of hydrocarbon type for the asphalt or asphalt blending stock and determining a critical physical property level which, when achieved, results in a product having a mutagenicity index of less than about 1.0. Process conditions are established so that a product stream achieving the desired physical property level can be produced. Non-carcinogenic asphalts and asphalt blending stocks are then processed utilizing the conditions so established.
