(1) The purification method of waste glycerol was optimized in order to remove the waste glycerol compounds which negatively affect the reformation process. These compounds are inorganic salts, and heavy molecules which remained in waste glycerol after triglyceride destruction (mono, di-, and triglycerides, soaps, free fatty acids).
(2) The catalytic reactor was integrated in the laboratory installation for glycerol steam reforming and the laboratory technology was established: Ni/Al2O3 catalysts, 550°C and atmospheric pressure.
(3) Study of the techno-economic and environmental performances of glycerol reforming for hydrogen production was made for 4 cases: (1a) catalytic reformation of glycerol without CO2 capture; (1b) catalytic reformation of glycerol with CO2 capture by adsorption in methyl-diethanol amine; (2a) autothermal reformation of glycerol without CO2 capture; (2b) autothermal reformation of glycerol with CO2 capture by adsorption in methyl-diethanol amine. The catalytic reformation process, with or without CO2 capture is more energetic efficient than autothermal reformation with aproximatelly 9 percent of net accumulated energy. For the same 4 cases, the economic assessments showed that the recovery of the initial investment depends on the technology used and is approximately 12 years.
