Use of Response Surface Methodology in Optimizing the Production yield of Biofuel from Cashew Nut Shell through the Process of Pyrolysis

Abstract A fixed bed pyrolysis reactor was used to pyrolyze Cashew nut shell (CNS). Response Surface Methodology (RSM) then study the process. One Factor at a Time (OFAT) experiment applied using different factors and levels. The OFAT results showed that highest liquid yield 57.8 wt.%. Two levels from each factor were chosen run RSM (applying Central Composite Design (CCD)) by forming two three (2 3 ) design. quadratic model suggested Expert (version 11) software predict yield. maximum 61.3 wt. %.
