Pyrolysis of lignocellulosic biomass with acidic pre-treatment to produce valuable bio-chemicals has been carried out in an integrated pyrolysis-gas chromatograph/mass spectrometry system. Three different waste biomasses (fir wood sawdust, pine wood sawdust and nutshell) were subjected to acidic solution to specify the acid pre-treatment effect on biomass chemical structure, thermal degradation profile and pyrolysis products. Post acid pre-treatments, the changes in the biomasses and thermal degradation profile were studied through proximate, structure and ultimate analysis and thermogravimetric. The pre-treatment significantly reduced the inorganic, cellulose and hemicellulose content in biomass samples. According to the pyrolysis experiment results, acid pre-treatment provided the increasing of the amount of phenolic in the degradation products at 10 min pyrolysis time. All the results would assist further understanding of thermal decomposition and thermo-chemical application for bio-fuels and bio-chemicals of fir wood sawdust, pine wood sawdust and nutshell.

Acid pre-treatment effectively modifies biomass characteristics, reducing ash content and enhancing thermal stability.The process increases the phenolic content in pyrolysis products, particularly at a 10-minute reaction time.These findings contribute to a better understanding of biomass thermal decomposition and its potential for biofuel and biochemical production.

Penelitian lebih lanjut perlu dilakukan untuk mengoptimalkan konsentrasi asam dan waktu pre-treatment guna memaksimalkan produksi senyawa fenolik. Studi komparatif terhadap berbagai jenis asam dan metode pre-treatment lainnya, seperti penggunaan enzim atau radiasi, dapat dilakukan untuk menemukan pendekatan yang paling efisien dan ramah lingkungan. Selain itu, penelitian mengenai pemanfaatan bio-oil yang kaya fenolik sebagai bahan baku untuk sintesis bahan kimia bernilai tinggi atau sebagai aditif bahan bakar juga sangat menarik untuk dieksplorasi. Penelitian ini dapat membuka peluang pengembangan teknologi konversi biomassa yang lebih berkelanjutan dan ekonomis, serta berkontribusi pada diversifikasi sumber energi dan bahan baku terbarukan.
