Synthesis And Optimization Of Sugarcane Bagasse Derived Sulfonated Biochar Based Solid Acid Catalyst

Abstract

Sulfonated Biochar Based Solid Acid Catalyst Is An Important Biomass Based Catalyst. The Synthesis Of Sulfonated Biochar Based Catalyst From Sugarcane Bagasse For The Biomass Conversion Is One Of Great Practical Significance For The Comprehensive And Efficient Utilization Of Biomass. Sugarcane Gasses Was Found To Be Thermally Stable Based On Tga Analysis, Making It Suitable As Raw Material For Catalyst Synthesis. The Sulfonation Variables For The Synthesis Of Sulfonated Biochar Based Catalyst Were Optimized Using Response Surface Methodology (Rsm). Effects Of Three Sulfonation Variables Namely, Temperature (100 ??180???), Time (3-25 Hr) And Ratio Of Concentrated Sulfuric Acid To Biochar (5:1- 25:1 Ml/G)Were Investigated. Among Three Parameters Studied, Ratio Of Sulfuric Acid To Biochar Was Found To Be The Most Significant Parameter In The Sulfonic Group Acid Density Since It Shows Low P-Value (0.0001). The Optimum Sulfonation Conditions Generated Numerically By TheRsm Were 135 ??? Of Temperature, 13.3 Hr Of Time, And 24:1ml/G Ratio Of Concentrated Sulfuric Acid To Biochar Which Gave 0.596 Mmol/G Amount Of Sulfonic Group Density. The Optimum Sulfonated Biochar Based Catalyst Was Characterized By Acid Group Titration, Thermo Gravimetric Analysis (Tga), X-Ray Diffraction (Xrd), Fourier Infrared (Ftir)Spectroscopy And Scanning Electron Microscopy (Sem) To Establish Its Properties.
