Evolutionary behavior of syngas characteristics evolved during the gasification of cardboard has been examined using a batch reactor with steam as a gasifying agent. Evolutionary behavior of syngas chemical composition, mole fractions of hydrogen, CO and CH4, as well as H2/CO ratio, LHV (kJ/m3),...

This study characterizes the chemical kinetics for the reduction and elimination of char particles using air and pure oxygen as the oxidants. Commercial carbon black was used as char for the experimental studies reported here. Different oxidant injection flow rates have been examined at various...

Main characteristics of gaseous yield from steam gasification have been investigated experimentally. Results of steam gasification have been compared to that of pyrolysis. The temperature range investigated were 600-1000 °C in steps of 100 °C. Results have been obtained under...

Evolutionary behavior of syngas chemical composition and yield have been examined for paper and cardboard at three different temperatures of 800, 900 and 1000 °C using CO2 as the gasifying agent at constant flow rate. Specifically the evolution of syngas chemical composition with time has...

Results are presented from successfully designed and fabricated meso-scale ceramic combustors that incorporate internal thermal energy recirculation. The combustor provided sustained operation using propane and air as the reactants. Flames could be obtained well below the normal quenching...

Experimental investigations on the effect of different amounts of toluene addition to H2S combustion in oxygen under Claus condition (Φ=3) are presented. Three toluene concentrations of 0.5%, 1% and 5% in H2S are presented and compared with the baseline case of 100% H2S oxygen combustion....

Results are presented to examine the combustion of acid gas (H2S and CO2) in hydrogen-fueled flames using a mixture of oxygen and nitrogen under Claus conditions (Φ=3). Specifically the effect of oxygen enrichment in the above flames is examined. The compositions of acid gas examined are100%...

Mangrove is a biomass material that grows in wetland sea waters and is often used to produce charcoal due to its unique characteristics of long and sustained burning and negligible residue. High temperature pyrolysis has been conducted for mangrove biomass in a laboratory scale semi-batch...

Investigation of sulfur chemistry of hydrogen sulfide in methane/air flame under different equivalence ratios is conducted. A range of equivalence ratios extending from fuel-lean (Φ=0.5), stoichiometric (Φ=1.0), to fuel-rich (Claus condition, Φ=3.0) are examined here. Hydrogen sulfide,...

Results are presented on the toluene destruction using oxygen enriched air as the oxidant with addition of defined amounts of H2S and toluene into H2/air flames under fuel-rich mixture conditions at equivalence ratio of Φ=3 (Claus condition). The oxygen enrichment allowed variation of...
