Heating value of syngas

WebThe following table shows the widely varying characteristics desirable for the principal uses of syngas, including use as fuel gas to fire boilers or turbines in power cycles, use of syngas as feedstock for production of synthetic fuels such as gasoline, use as feedstock for methanol synthesis, and use as feedstock for production of hydrogen. WebThe higher heating value of the exiting gases was estimated from the syngas composition. The average tar and particulate concentrations of the sample runs were 1.8 to 3.1 g/m 3 and 5.2 to 6.4 g/m 3, respectively. The higher heating values of the syngas ranged between 4.38 and 4.55 MJ/m 3.
