Coffee is one of the most consumed beverages in the world, which generates a large amount of residue called, spent coffee grounds (SCG). Due to its high lipid content (10–15 wt %), the SCG has a potential of producing 1.3 billion liters of biodiesel annually. Fast pyrolysis is commonly used for the liquefaction of solid SCG, which resulted in the production of fatty acid rich bio-crude. We examined the ability of mesoporous zeolites (SAPO-11, and MCM-41) for the catalytic cracking of oleic acid, as a model compound of fatty acids rich bio-crude in a continuous flow reactor. The oleic acid was fed into the reactor at the flowrate of 15 g/min, and the reactions were conducted at the temperature range of 400 to 500 °C. The GC-MS results showed that the oleic acid was completely converted into the hydrocarbons and aromatics rich oil over MCM-41 with maximum selectivity of 90 %, which mainly consisted of gasoline fractions (45 %). |
