Experimental results are presented on the role of benzene addition to H2S combustion at an equivalence ratio of three with respect to H2S (Claus condition) and complete combustion of benzene. The results are reported with 0.3%, 0.5% and 1% benzene addition to H2S/O2 flame. Combustion of H2S and...

A micro-thermocouple, microphones and microphone probes were employed to provide detailed information on key ongoing processes in a premixed swirl flame. High frequency pressure and temperature measurements were carried out to identify temperature field and acoustic characteristics of a swirl...

Steam gasification of sugarcane bagasse has been investigated. A semi batch reactor with a fixed amount of sugarcane bagasse sample placed in steady flow of high temperature steam at atmospheric pressure has been used. The gasification of bagasse was examined at reactor and steam temperatures of...

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....

Lignite pyrolysis and gasification has been conducted in a semi batch reactor at reactor temperatures of 800–950°C in 50°C intervals. CO2 has been used as the gasifying agent for gasification experiments. The objective of this investigation is to understand the mechanism of syngas evolution...

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,...

The effect of particle size, porosity and reactor temperature/reaction rate constant on the progress of a char particle conversion has been investigated numerically by solving the transport equation inside a reacting char particle. Numerical simulations have been conducted for three cases that...

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...
