Abstract

116%">Problem Statement: UAE has over 40 million date palm
trees. On average approximately a total of 40 kg waste per tree is produced and
therefore huge amount of waste is generated (about 1.2 million tons annually). Most
of the waste from palm trees is currently turned into compost or burned to
generate heat despite the high content of cellulose, hemicelluloses and lignin.
Literature has reported mso-bidi-font-size:11.0pt;line-height:116%;font-family:" times new roman mso-fareast-font-family:> possibility font-family:" times new roman>
of converting " times new roman> different biomass into various High Value Chemicals (HVC)
considering lignocellulose components as a base feed stock. However, despite
the abundancy, little effort has been registered for conversion of date palm
biomass to HVCs especially from Oil rich countries. The purpose of this study
is to use Reductive Catalytic Fraction to convert UAE date palm biomass to HVCs
using a high-pressure high temperature Parr reactor, with an aim of providing enough
knowledge of lignocellulose and optimization conditions for an overall goal of production
of HVC from the same biomass and investigate the gases evolved for possible
future LPG replacement from biorefinery. Methods & Experimental procedure: Thermogravimetric
analysis, SEM measurements, high-pressure high temperature Parr reactor for
biomass conversion in this study (see Figure 1.) was carried out; Q500 TA
Instrument using N₂, 20 mL/min. 10, 15 20 and 25°C/min, controlled
from 25 to 900 °C, A JEOL/EO Scanning Electron Microscope and ethanol-benzene
free extractive sample were used with commercial NiAl alloy catalyst.

116%">Results: From TGA, the initial weight was recorded
continuously as a function of temperature and time. Sample’s Thermal stability,
degradation regimes and temperature were obtained. Existence of three major
lignocellulose fractions was shown and hence guarantee for anticipated HVCs
from this biomass. SEM images revealed different morphologies showing minimal
visible surfaces changes of the catalyst, hence indicating ability to be
recycled. The process revealed significant hydrocarbon production in the gas
stream and appreciable conversions in the liquid product stream. KO;mso-no-proof:yes"> Conclusion &
Significance: Applied technique can successfully depolymerize lignin complex
structure to HVCs with appreciable conversions and useful gas products. The
catalyst used can easily be separated out of biomass after reaction making it
cheaper and easy for re-use. Recommendations are made for further                  Fig. 1 Schematic layout for date palm waste to

biomass prior to processing in a bio-refinery and further analysis of liquid
product is underway to determine the selectivity and yield of individual HVCs
produced.
