Technology of Catalytic Cracking Pyrolysis for Liquid Fuels Production from Waste Tires Using Acid Zeolite and Silica Catalysts

Tires made from rubber is one of the types of polymers (Polystyrene), which can be recycle for processing of waste tires into energy that is by means of cracking process. This process takes place at high temperature so it takes a catalyst. Catalyst acid zeolite and silica was able to increase the process of pyrolysis by means of lowering the temperature and time of decomposition, so obtained results in the form of liquid fuel. Method in the writing this scientific paper is a research method which consists of stages the design of equipment, research and analysis phase of the product. At the beginning of the study, the variables vary is the weight of the catalyst with the aim to get the weight of the optimum catalyst that produces the maximum product. From the weight variation the catalyst is done (5:1, 5:2, and 5:3) the volume of product that most i.e. in the ratio of raw materials and catalyst 5:2. At later stages done temperature variations in the ratio of raw materials and optimum catalyst (5:2) i.e. 450, 550, and 650°C. From the results of the experiment produced optimum temperature i.e. 550°C with product volume 220 ml. Based on the results of the analysis of such product approaching nature physical on diesel fuel with the density of the product of 0.815-0.88 gr/ml, and the heat value of the product is at the range 10496,18-14227,93 cal/gr.
