Tujuan dan penelitian adalah untuk memperoleh studi fundamental untuk mendukung pengembangan dan proses desain hydrothermal treatment dan tempurung kelapa sawit sebagal bahan dasar, khususnya efek suhu dan kualitas produksi biomasa. Hydrothermal treatment dan tempurung kelapa sawit dilakukan pada suhu 200-380°C. Ditemukan bahwa berdasarkan kenaikan suhu treatment, produk padat cenderung turun, ini disebabkan karena terjadi pembentukan produk gas dan cair. FTIR spectra menunjukkan munculnya grup rantal aromatic, aliphatic, ester pada produk padat dan eksperimen acetone’di tiap treatment suhu. Analisa TOC dan GC-MS dilakukan untuk mengamati senyawa organik di produk cair, hasH TOC cenderung naik pada suhu rendah dan turun pada suhu 300°C. Produk gas diamati dengan GC-4C membentuk gas H2, CO, CO2 dan CH4. Dengan menganalisa hash variasi produk padat, cair dan gas dan hydrothermal treatment, diketahui bahwa metode ¡ni berguna pada proses pelepasan hemicelluloses dan lignin dan biomasa kelapa sawit tanpa tambahan katalis dan larutan organik.

The purpose of this work is to provide a fundamental studies support for the hydrothermal treatment process design and development from palm shell as material, performing an analysis process of hydrothermal treatment, especially the effect of temperature on Biomass production quality. Hydrothermal treatment of palm shell is conducted in temperature 200-380ºC. It was found that by the increasing of temperature treatment, the solid product tends to decrease, thus causes by the decomposition of liquid and gas product. FTIR spectra showed the functional groups of aromatic ring, aliphatic rings, esters content in solid product and acetone experiment from solid product each temperature treatment. TOC and GC-MS was performed to investigate the organic compounds in liquid product, TOC results tend to increase in lower temperature and decrease in 300ºC. Gas product was observed by GC formed H2, CO, CO2 and CH4 gases. By investigation of various products from solid, liquid and gas product with hydrothermal treatment, this method is promising for removal of hemicellulose and lignin from palm shell biomass without any catalyst and organic solvent.
