What is Catalytic Pyrolysis of Coconut Oil Soap Using Zeolites for Bio-hydrocarbon Production about?

Soap pyrolysis is an interesting route for green jet fuel production because it is a simple process without required hydrogen supply and operated under atmospheric pressure. However, coke as an undesired product is often formed in high yield. In this investigation, pyrolysis of coconut oil soap was performed via catalytic routes in a batch reactor to avoid excessive coke formation. Two zeolite types, faujasite (H-Y) and mordenite (H-M), were evaluated as catalysts for pyrolysis. Catalyst loadings were studied for H-Y 20%, 40%, and 60%. Product analysis was performed by gas chromatography-mass spectrometry (GC-MS) to identify bio-oil components. Physical properties analysis was performed to determine the density and viscosity of the bio-oil product. The bio-oil produced from thermal process is composed of olefins C 6 -C 18 (43.4%), ketones (38.6%), and paraffins C 7 -C 18 (14.8%). Thermal pyrolysis showed low yield bio-hydrocarbon (olefins and paraffins) C 8 -C 16 (11%) and high solid residual formation (23.4%). Catalytic pyrolysis using zeolites of reduced solid residual formation to 10.6% with high bio-oil yield; however, the undesired carboxylic acid products were produced. Catal
