Due to its origin, crude tall oil has a very complex composition, containing resins, sterols unsaponifiables (5-10%), resin acids as abietic acid, fatty acids (mainly palmitic, oleic and linoleic acid), alcohols and other alkyl derivatives of hydrocarbons. Therefore, CTO feedstock has been widely characterized, in order to determine its composition and chemical properties, such as acid number, FFA, etc. Then, the preliminary catalytic tests for bio-fuels production via CTO hydro-deoxygenation were carried out with a commercial catalyst, at 21 bar of total pressure and varying the reaction temperature from 250°C to 300°C. Two different start-up protocols were employed (i.e. with or without simulating stream pre-passivation), concerning the feeding procedure and the composition of the reactant stream initially introduced into the reactor.

Abstract

Due to its origin, crude tall oil has a very complex composition, containing resins, sterols unsaponifiables (5-10%), resin acids as abietic acid, fatty acids (mainly palmitic, oleic and linoleic acid), alcohols and other alkyl derivatives of hydrocarbons. Therefore, CTO feedstock has been widely characterized, in order to determine its composition and chemical properties, such as acid number, FFA, etc. Then, the preliminary catalytic tests for bio-fuels production via CTO hydro-deoxygenation were carried out with a commercial catalyst, at 21 bar of total pressure and varying the reaction temperature from 250°C to 300°C. Two different start-up protocols were employed (i.e. with or without simulating stream pre-passivation), concerning the feeding procedure and the composition of the reactant stream initially introduced into the reactor.
