Abstract (en)
[origin: WO2017109402A1] Disclosed is a method for preparing a solid bitumen material at ambient temperature, said method comprising at least the steps of: a) preparing a stabilized emulsion of bitumen drops in a water phase that has a pH of 2 to 4; b) preparing a silica sol or silica gel from a first silicon oxide precursor that has a pH of 2 to 4; c) mineralizing the emulsion of bitumen drops from step a) with the silica sol or gel from step b); d) mineralizing the emulsion of bitumen drops from step c) having a maximum pH of 1 with a second silicon oxide precursor; e) separating the material from the water phase.
