Characterization of Liquid Volatile Matter (LVM) of Cashew Nut Shell using Pyrolysis and Gas Chomatroghaphy

Abstract

Cashew nut areexcellent products in Southeast Sulawesi. Cashew nut is one part of the cashew plant untapped waste. Cashew nut shell potential as a producer of liquidvolatile matter (LVM) and charcoal because it contains lignocellulos. LVM is the smoke condensation products obtained from the pyrolysis reactor can used foradhesive of briquettes hybridapplication. The aim of this reseach is to produce LVM of cashew nut shellby pyrolysisand analyze the content byGas Chromatography(GC). The research procedure begin with drying the cashew nut, the sample inserting into the pyrolysis reactor then heating with three variations of temperature respectively is 400°C, 500°C and 600°C. Cashew nutshell have been heating by pyrolisis processwith high temperatures resulting chorcoal and LVM separately. Volume LVM measured,then identify is components using GC. LVM obtained respectively 200ml kg-1, 340 ml kg-1, and 340 ml kg-1. Chromatogram of the GC from LVM of cashew nut shell has ammonia, hexane, acetic acid, propanone and phenol. Phenol compounds can be used as a adhesive for hybrid briquettes applications.
