Baru-baru ini, dengan pertimbangan ke atas alam persekitaran dan ekonomik, minat terhadap penggunaan biojisim untuk penghasilan tenaga dan bahan kimia semakin meningkat. Tempurung kelapa sawit merupakan salah satu bahan buangan utama di Malaysia. Pirolisis adalah salah satu teknik termo-kimia yang mempunyai harapan untuk penghasilan tenaga daripada biojisim. Dalam kajian awal ini, proses pirolisis dikenakan ke atas tempurung kelapa sawit dengan menggunakan analisis termogravimetrik (TGA). Kesan kadar pemanasan ke atas sifat pirolisis telah dikaji. Parameter kinetik juga telah dikenal pasti dengan menggunakan kaedah kamiran. Kertas kerja ini juga menerangkan keputusan uji kaji dari sebuah radas skala kecil lapisan terbendalir pengedaran semula(CFB), yang terletak di SIRIM Berhad, Shah Alam, yang mana sesuai untuk uji kaji penggasan dan pembakaran pelbagai bahan biojisim. Objektif kajian ini adalah untuk mengkaji kesesuaian bahan bakar yang terpilih untuk penghasilan tenaga dengan menggunakan CFBC dalam masa yang sama mengambil berat terhadap penghasilan gas emisi. Parameter operasi (seperti suhu, jenis biojisim, kadar suapan, kadar pemanasan, tekanan, suapan udara utama dan konfigurasi reaktor) adalah dipercayai mempengaruhi secara langsung kepada proses pirolisis biomas. Suhu merupakan salah satu pemboleh ubah yang penting, maka dalam kajian ini telah dibuat untuk mengkaji kesan suhu terhadap proses pirolisis. Kandungan CO, NOx dan CO2 dalam gas emisi telah diukur. Prestasi pembakaran telah dikaji dengan mengubahkan kadar aliran udara utama masuk ke dalam kebuk pembakaran CFBC. Bahan emisi NOx didapati dalam julat 38 ke 75 ppm manakala bahan emisi CO telah didapati tinggi pada kemasukan kadar aliran udara utama yang tinggi. Kata kunci: biojisim, emisi, parameter kinetik, tempurung kelapa sawit, pirolisis, TGA, termo–kimia Recently, owing to environmental and economic considerations, interest in utilizing biomass for the production of energy and chemicals is increasing. Palm oil shell wastes are one of the main agriculture waste in Malaysia. Pyrolysis is one of the most promising thermochemical techniques for recovering energy from biomass. Pyrolysis of oil-palm shell waste was first carried out using thermogravimetric analysis (TGA). The effects of heating rate on the pyrolytic properties were investigated. The kinetic parameters have also been determined using integral method. This paper also describes the experimental results from a bench-scale circulating fluidized-bed (CFB) test rig, installed at SIRIM Berhad, Shah Alam, suitable for gasification and combustion experiments using different biomass materials. The purpose of the tests was to investigate the suitability of the selected fuels for energy production using Circulating Fluidised Bed Combustor (CFBC) while taking care of the flue gas emissions. Operating parameters (such as temperature, type of biomass, feeding rate, heating rate, pressure, primary air and reactor configuration) are believed to influence significantly the pyrolysis of a biomass. Temperature is one of the most important operating variants so the experimental studies were done to investigate the influence of temperature on pyrolysis. the concentrations of CO, NOx and CO2 in the flue gas were measured. The combustion performances were evaluated by varying the primary gas flow through the CFBC tubular furnace. the emission of NOx ranged from 38-75 ppm while the CO emissions were high for higher primary air flow rates. Key words: biomass, emissions, kinetic parameters, oil palm shell waste, pyrolysis, TGA, thermochemical

The purpose of this research is to know the influence of pressure and use of conplast against mechanical properties which are a Modulus of Elasticity (MOE) and Modulus of Rupture (MOR) of plasterboard. The study is done because still low quality of plasterboard made from a mixture of ashes of oil-palm shell especially of the mechanical properties compared to the controls. The method of this reserach used variation of printed pressure and the addition of conplast. Test result is obtained that the highest value of Modulus of Elasticity (MOE) 90875.94 Kg/cm2, Modulus of Rupture (MOR) 61.16 Kg/cm2 and density values in generally good printed at the pressure 60 g/cm3 and the addition of conplast 25% as well as the composition of the ash of palm shell oil 40%: limestone 40%: cement 15%: fiber 5% and 300 mL of water. ABSTRAK Tujuan dari penelitian ini adalah untuk mengetahui pengaruh tekanan dan penggunaan conplast terhadap sifat mekanik yaitu kuat lentur dan keteguhan patah eternit berbahan dasar abu cangkang sawit. Penelitian ini dilakukan karena masi rendahnya mutu eternit berbahan campuran abu cangkang sawit dari bolier khususnya sifat mekanik dibandingkan dengan kontrol.

One of waste agriculture materials is oil palm shell ash. It has been producing in high quantity in palm oil mill, and for storage of that an investment requires. In this paper, an attempt has been made to analysis effect of oil palm shell ash on compressive and flexural strength of cement mortar. The compressive strength and flexural strength of cement mortar has been measured. To improve accuracy of work 50% cement and 50% fine sand has been proposed in cement mortar mix design. The results have been indicated that the effect of OPS ash on flexural and compressive strength of cement mortar is not same. The deflection, load sustainability and time to failure for compressive strength have independent fluctuation of flexural strength. The positive and negative effect of OPS ash on mechanical properties of cement mortar has been observed. The morphology of crack failure has not been investigated. The work can be continued with many waste agriculture materials. Keywords: waste agriculture, deflection, load sustainability, time to failure.

The mechanical properties of oil palm shell (OPS) composites were investigated with different volume fraction of OPS such as 0%, 10%, 20%, and 30% using unsaturated polyester (UPE) as a matrix. The results presented that the tensile strength and tensile modulus of the UPE/OPS composites increased as the OPS loading increased. The highest tensile modulus of UPE/OPS was obtained at 30 vol% of OPS with the value of 8.50 GPa. The tensile strength of the composites was 1.15, 1.17, and 1.18 times higher than the pure UPE matrix for 10, 20, and 30 vol% of OPS, respectively. The FTIR spectra showed the change of functional group of composites with different volume fractions of OPS. SEM analysis shows the filler pull-out present in the composites which proved the poor filler-matrix interfacial bonding.
