Abstract
The present invention consists of the formulation of Petroleum Asphalt Cement (CAP) produced by the asphalt residue (RASF) or vacuum residue (RV) using Plastic Pyrolysis Oil (OPP) as an alternative diluent and may optionally consist of elemental sulfur as well as typically fossil diluents with reduced levels. The present invention further describes the process for obtaining said CAP composition.
Claims10
Process for obtaining CAP characterized by comprising the following steps:
- optionally, cutting the OPP at 200° C./200° C.+ during the distillation step;
- mixing the OPP diluent with RV or RASF in a low shear mixer, at a temperature between 115° C. and 130° C., for 30 min;
- and
- optionally, adding 0.25% by mass of elemental sulfur to the mixture from the previous step with constant stirring and a temperature between 115° C. and 130° C. for 3 hours;
- this step being dependent on the consistency of the final product (CAP).
