Abstract:
1. A method of manufacturing aromatic hydrocarbons from a tall oil-based raw material, the method comprising: feeding, into a fixed catalyst bed, hydrogen gas and a bio oil, which consists of 2-90% of tall oil fatty acids, 2-98% of tall oil resin acids and, optionally, other vegetable oils; catalytically deoxygenating the bio oil in the bed with hydrogen; cooling the flow exiting the bed, and dividing the flow into a hydrocarbon-bearing liquid phase and a gas phase; and recovering one or more aromatic hydrocarbons selected from a group comprising o-xylene, m-xylene, p-xylene and a cymene from the hydrocarbon-bearing liquid phase, wherein a deoxygenation catalyst and a cracking catalyst are used, which are different from each other and located sequentially apart from each other in the catalyst bed that is formed by a solid bed material.
