Pyrolysis-catalytic steam/dry reforming of processed municipal solid waste for control of syngas H2:CO ratio

The production of syngas from the pyrolysis-catalytic reforming processed municipal solid waste in form refuse derived fuel has been investigated experimentally using a two-stage fixed bed reactor with 10 wt% Ni–Al2O3 catalyst. gases used were combination steam and carbon dioxide (dry reforming). main focus research was to manipulate H2:CO ratio for targeted end-use applications by optimizing process conditions, including input steam/CO2 gas ratio. experimental results showed that at higher steam:CO2 ratios, there marked increase H2 yield due endothermic nature CO2 processes. catalytic temperature also had major influence on yield, increasing raising hydrogen maximum ?41.0 mmol gRDF?1 955 °C catalyst temperature. molar affected variables interdependent them. For example, an as content increased, produced ?4.7:1 achieved 75:25 700 °C. Whereas, gas, product ?1:1. Also, 50:50, ?2:1 ?3:1. Design Experiments (DoE) modelling carried out data identify conditions would produce target 1:1 2:1. predicted optimised DoE close thereby validating model.
