This work describes research conducted on the zeoforming process of rapeseed oil and using zeoformat as a feedstock for hydroconversion process leading to hydrocarbon fuel biocomponents. The raw rapeseed oil and the products, including the zeoformat of the raw rapeseed oil and the hydroraffinate of the raw rapeseed oil zeoformat, were examined using ¹H NMR techniques to confirm the occurrence of the oligomerization of fatty acids. Based on the tests performed, it was determined that, during the zeoforming of the vegetable oil, partial decomposition processes occurred in the triglycerides. Monoglycerides, diglycerides, and carboxylic acids were formed, followed by the occurrence of oligomerization processes that led to the creation of both branched aliphatic structures and aromatic structures, which were most likely benzene rings substituted with diverse functional groups.
