摘要：
This research explores optimal reaction conditions for the generation of gas products, through the slow pyrolysis of apple pomace, to be used as a feedstock for the production of H-2 by the absorption enhanced reforming of methane (AER). Pyrolysis was performed at 300-450 degrees C and heating rates 5-20 degrees C/min. Gases, tars and chars were quantified at different heating rates and isothermal conditions. Results indicate that at 400 degrees C a maximum of 71.5% W of non-condensable volatile matter (NCVM) can be obtained along with 25.4% W of condensable volatile matter (CVM), while only 3% W of residual matter (RM). At these conditions (NCVM) a gas composition of 49.8% CO, 26.8% CO2 and 23.4% CH4 (Vol) was generated. A thermodynamic analysis of this product gas was performed under AER through CO2 absorption by CaO. Calculations using a steam to methane ratio of 3.5 and 3.5 mol of CaO/mol of CH4 indicate that a maximum H-2 production is achieved at 715 degrees C containing 73.0% H-2, 19.1% CO, 5.3% CO2 and 2.5% CH4 with no carbon formation.
