The Fixed Bed Reaction of Residual Natural Rubber for Oil Production by Pyrolysis Process

Abstract:

The aim of this study is to use pyrolysis reaction to produce oil product as a fuel or chemical feedstock. The fixed bed reactor was used as a pyrolysis system. The pyrolysis reaction of residual para rubber was operated in the absence of catalyse. The operating conditions such as particle size (0.5 and 1.0 cm³) and pyrolysis temperature (500, 550 and 600 ^OC) were studied under N₂ conditions and retention time 90 min. The result shows the para rubber size 1.0 cm³ can be produced liquid phase more than of para rubber size of 0.5 cm³. The optimised condition with the highest oil yield was at 550^OC with rubber size of 1.0 cm³. The percentage of the product was 60% of liquid, 35% of gas and 5% of solid (char). Furthermore, the FTIR result can be presented the supported evidence that the transformation of aliphatic contents to be aromatic contents was increased with increased temperature. Also, GCMS analysis was used for the identification and quantification of the product. It was found 5 major products that can be used as a chemical feedstock. The maximum amount of component was 2-Benzenedicarboxylic acid, diisooctyl ester (Isooctyl phthalate) with 22.08%. This is a plasticizer with higher cost than fuel.
