The paper discusses the influences of percentages of calcium oxide catalysts and operation temperature of catalytic co-pyrolysis on the products and characteristis of upgraded bio-oil. Catalytic co-pyrolysis was carried out in a fixed-bed reactor with an inner diameter of 30 mm and and a length of 300 mm. The treated EFB was mixed with the waste tire with a weight ratio of 25:75 and was added calcium oxide with catalysts with percentages of (1,2,3,4,5%). The mixed raw material and calcium oxide were put into the catalytic co-pyrolysis reactor and heated at 400 – 550 °C. The highest bio-oil yield is generated on the use of a CaO/raw material ratio of 3% w/w and temperature of 500 °C was 38.3 wt%. Bio-oil produced from catalytic co-pyrolysis of 25% palm oil empty fruit bunch (POEFB) and 75% waste tire using 3% calcium oxide catalyst has physical properties close to diesel oil. The GC–MS analysis has revealed that bio-oil contains hydrocarbon of 94.01% and oxygenated compounds of 5.99%.
