Composition and morphology of biomass-based soot from updraft gasifier system

Abstract

Soot is an aerosol formed by incomplete combustion of carbonaceous materials, and its formation in biomass gasification is inevitable. It is crucial to know the properties of the soot produced in the exhaust of gasification reactors in order to appreciate both its advantages and disadvantages. In this study, a variety of analytical techniques were used to examine the content and morphology of biomass soot produced by a top-lit updraft gasifier. The results of the experiment revealed that carbon and oxygen make up the majority of the soot, with minor amounts of other components. Both aromatic and aliphatic groups with significant oxygen concentrations can be seen in the soot based on the distribution of functional groups. The morphology revealed an uneven, stratified, amorphous sample. Meanwhile, the sample had a surface area of 193.8 m2/g and a pore diameter of 2.68 nm. These porous qualities point to a potential use of the soot sample as an adsorbent in water filtration after activation.

“…At 1491 cm À1 , there is a peak associated with the vibrations of the N-H amine group, and various bending vibrations of C-H bonds are observed at 1450 and 1375 cm À1 . 9 Additionally, a minor peak at 1027 cm À1 can be attributed to deformations of the hydroxyl group, 31,32 while other bending and stretching vibrations related to the aromatic components of the polymer are represented by peaks at 906, 747, 694 and 536 cm À1 . 33 The composites that incorporate rubber, such as PR18PF6, PR12PF12 and PR6PF18, display FTIR spectra similar to that of PBR, with additional peaks attributed to rubber functional groups, particularly at 3059 and 2047 cm À1 .…”
