Pyrolysis of Coconut Shell: An Experimental Investigation

The Journal of Engineering Research [TJER], 2009
 Fixed-bed slow pyrolysis experiments of coconut shell have been conducted to determine the effect of pyrolysis temperature, heating rate and particle size on the pyrolysis product yields. The effect of vapour residence time on the pyrolysis yield was also investigated by varying the reactor length.

Chemical Identification of Coconut Shell Liquid Smoke

IOP Conference Series: Earth and Environmental Science, 2019
Abstract Coconut shell liquid smoke is produced from a chemical pyrolysis process that involved smoke bearing water vapor from burning coconut shells in very high temperature. Materials used in this study were coconut shell liquid smoke with three different grades. Visually, grade 1 liquid smoke was clear.
