mso-ansi-language:EN-US'>Experiments for the hydrotreatment
of Refined, Bleached and Deodorized Palm Oil (RBDPO) were carried out in a
batch reactor at temperatures varying from 335°C to 365°C and pressures in the
range of 30 bar to 60 bar. Hydrotreatment
transforms vegetable oils, in this case RBDPO, into a zero-sulfur liquid with
properties that resemble those of diesel fuel. In a hydrotreatment
reactor, high-pressure addition of hydrogen reduces the size
of the triglycerides molecules through deoxy and decarbonate hydrocracking. The experiments to
determine the HVO kinetics involved a commercial catalyst. The catalyst presulfurization for activation and stabilization was
carried out ex situ in a continuous fixed bed reactor. DMDS was entrained by a
nitrogen flow at 400°C to guarantee, due to the decomposition of DMDS, that the
catalyst was exposed to H2S for 9 hours. The activated catalyst was
then used in a batch reactor to carry out the hydrotreatment
reaction. The liquid products formed through the reaction (mainly fatty acids
and hydrocarbons) were analyzed by means of a GC-MS and the gaseous products
were characterized with a micro GC. The sample of RBDPO was obtained from a local
palm oil company and was mainly composed of oleic (38.8 %w), palmitic (34.6 %w), linoleic (13.1 %w) and stearic (8.1 %w)
triglycerides. The analysis of the products showed the presence of hydrocarbons
varying from 13 to 20 carbon atom; palmitic, oleic
and steric acids and di and monoglycerides. Conversion
of the RBDPO was higher than 50% for all the experiments. A mechanism that
considers the conversion of triglycerides to mono-glycerides and carboxylic
acids and the subsequent hydrodeoxygenated to form
hydrocarbons was proposed, as well as kinetic expressions for the reactions in
the mechanism following a constrained optimization procedure.
