Different approach to valorise the sweet sorghum using pyrolysis process to obtain valuable resources for energy production: bio-char, bio-oil and syngas are presented in the paper. In this study the influence of process parameters of slow pyrolysis on sorghum and straw were analysed. Temperatures used in the process varied from 400 to 800�C and heating rate parameter varied from 10�C . min-1 to 65�C . min-1. The experiments were conducted using a lab scale slow pyrolysis reactor with electric heaters, equipped with a thermo balance analyzer to collect data of pyrolysis process. The achieved product yield can vary significantly according to the slow pyrolysis parameters. The temperature influenced more on the bio-char yield compared to the heating rate parameter. The highest bio-char yield (over 35% weight,) was obtained at 400�C and heating rate of 10�C . min-1.

Tindak balas penggandingan beroksida metana (OCM) terhadap mangkin Li/MgO dioptimumkan menggunakan reka bentuk eksperimen daripada perisian ‘Statsoft Statistica’ versi 6.0. Pemboleh ubah yang di pilih dalam kajian ialah suhu operasi, jumlah kadar aliran suapan per berat mangkin (F/W), dan peratus berat Li yang dimasukkan ke dalam mangkin MgO, manakala penukaran metana, kememilihan C2, dan keberhasilan C2 merupakan sambutannya. Model persamaan diuji menggunakan analisis Anova dengan 99% darjah keyakinan. Metodologi sambutan permukaan (RSM) digunakan bagi menentukan sambutan optimum. Dengan menggunakan analisis varians dan eksperimen tambahan, kejituan model dapat disahkan. Kata kunci: OCM, pengoptimuman, reka bentuk eksperimen, metodologi sambutan permukaan Oxidative Coupling of Methane (OCM) reaction over Li/MgO catalyst was optimized using experimental design from ‘Statsoft Statistica’ version 6.0 software. The manipulated variables chosen in this study were operating temperature, total flow rate per weight of catalyst (F/W), and weight percent of Li doped into MgO catalyst, whilst methane conversion, C2 product selectivity, and C2 product yield were the responses. The equation model was tested with Anova analysis with 99% degree confidence. The Response Surface Methodology (RSM) was employed to determine the optimum responses. By means of variance analysis and additional experiments, the adequacy of this model was confirmed. Key words: OCM, optimization, experimental design, response surface methodology

Effects Of Temperature

The pyrolysis of three stalk was studied to estimate the effect of pyrolysis conditions on product yield, calorific value and proximate analysis. Heating rate and pyrolysis temperature were the main experimental parameters. According to the test, when the heating rates were at 5, 10 and 15°C/min, the low heating rate reacted more thoroughly, got high yield and kept more energy. As the pyrolysis temperature rising; namely 200,300,400 and 500°C;the fixed carbon and gross calorific value were increasing to be 68% and 24.72 MJ/Kg respectively, but the yield was decreasing.
