| Pyrolysis of Pomace | |
| The present research is aimed to explore optimal reaction conditions for the generation of a gas product, through the slow pyrolysis of pomace, to be used as a feedstock for the production of H2 by the absorption enhanced reforming of methane (AER) process scheme. Pyrolysis experiments were performed in a tubular reactor under conditions of rich syngas production (300–450 °C) and for specific solid heating rates (5-20 °C/min). Permanent gases (CO, CH4 and CO2), aromatic tars, and chars were quantified at different heating rates and isothermal conditions. Results indicate that at a temperature of 400 °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) was produced. At this favorable conditions (NCVM) a gas composition of 41% CO, 38% CO2 and 21% CH4 was generated. A thermodynamic analysis of this product gas was performed under the steam reforming of methane (SMR) combined with CO2 solid absorption by CaO for the production of high purity H2. Thermodynamic calculations using a steam to methane ratio (S/C) of 4 and 1 mol of CaO/mol of CH4 indicate that a maximum H2 production is achieved at 690 °C along with a composition of 74.1 % H2, 16.2% CO, 7.6% CO2 and 2.1% CH4 with no carbon formation. | |
