In this investigation, a mixture of sugarcane bagasse and rubber seed oil was subjected to pyrolysis for liquid fuel production, using aluminosilicates with different Si/Al ratios as catalysts prepared from rice husk silica and aluminum metal by electrochemical method.  A series of pyrolysis experiments was conducted at  the temperature range of 250 to 500^oC, with the main purpose to investigate the effect of the Si/Al ratios of the catalysts on the chemical composition of liquid fuels produced. The liquid fuels produced were analyzed using gas chromatography-mass spectrometry (GC-MS) technique for component identification. The experimental results show that the most intense production of liquid took place at the temperature range of 350 to 480^oC, while at lower temperatures gaseous product emerged as the main product.  Analysis of the product using GC-MS technique revealed the presence of a series of compounds in the liquids, and broadly belongs to hydrocarbon, alcohol, ester, ketone, aldehyde, and acid. The results display significant effect of the catalyst composition on the composition of the liquids.  The main trend observed is the tendency of increased the hydrocarbon content with decreased the Si/Al ratio of the catalyst, down to the ratio of 2.3 which produced  liquid fuel with the highest hydrocarbon content (85%).
