Stratified Downdraft Gasifier part 1
The datasets supporting this article have been uploaded as supplementary material: Gasifier Data. The correlation between thermochemical provenance and biochar functionality is poorly understood. To this end, operational reactor temperatures spanning the reduction zone , pressure and product gas composition measurements were obtained from a downdraft gasifier and compared against elemental composition, surface morphology and polyaromatic hydrocarbon content PAH of the char produced.

One of the most challenging issues concerning the gasification of oil palm fronds OPF is the presence of tar and particulates formed during the process considering its high volatile matter content. The amount of char, ash, and solid tar produced from the gasification process was measured in order to account for the mass and carbon conversion efficiency. Elemental analysis of the char and solid tar samples was done using ultimate analysis machine, while the relative concentration of the different compounds in the liquid tar was determined making use of a liquid gas chromatography GC unit. Average tar concentration of 4. Tar concentration in the raw gas sample was found to be higher compared to results for other biomass materials, which could be attributed to the higher volatile matter percentage of OPF. Currently, agricultural and domestic wastes make up a major part of biomass sources. However, the utilization of biomass energy is very small as compared to the conventional ones.

Over a million wood gasifiers were used to power cars and trucks during World War II. Yet, there are now only a few companies manufacturing gasifier systems. Thomas B.
Science Alert. Journal of Applied Sciences. Year: Volume: 8 Issue: 2 Page No. Siva Kumar , K. Pitchandi and E. Abstract: The conversion of biomass by gasification into a fuel suitable for use in a gas engine increases greatly the potential usefulness of biomass as a renewable resource. Gasification is a robust proven technology that can be operated either as a simple, low technology system based on a fixed-bed gasifier, or as a more sophisticated system using fluidized-bed technology.
