Effect of pyrolysis temperature and time of liquid smoke product from candlenut shell by pyrolysis process

Abstract

The purpose of this research particularly to acknowledge process conditions that give the best yield of liquid smoke products maximum resulted during pyrolysis process of biomass shell pecans. This Research conducted on a fixed batch reactor made of metal plate with a thickness of 3.0 mm. It carries 200 kegs in capacity. In this phase, the moisture of Candlenut shells might be kept in 10 - 12.5 wt. percentages. Process temperature variation in the temperature of 350 ° C, 450 ° C and 550 ° C. and variations of pyrolysis at 15, 30, 45 until 435 min. Product identification by GCMS at Optimum condition to determine the components of pyrolysis generated. The result of the research is the best process condition of liquid smoke during pyrolysis maximum of Candlenut shell by using pyrolysis method at the time of 210 min and 450 C Temperatures respectively can be obtained maximum product yield of liquid smoke around 2.62056%. Identification of products by using GCMS (GC Mass Spectrometry) at optimum condition at temperatures of 450 ° C. and pyrolysis time is 210 min showed that liquid smoke candle nut shell consist of 7 (Seven) components consist of Cyclopentanone, Cyclopenten1 2-one, 2-cyclopenten-1-one, Acetic acid, Furancarboxildehide 2, 2 and 2 methoxyphenol Methoxy-4- methyl phenol.
