The chemical reaction that occurs in the biodiesel processing is a type of reversible reaction between oil and methanol. Therefore, to increase the conversion of the reaction, the amount of methanol used is more than the stoichiometric equilibrium. The excess methanol is often difficult to recover after washing biodiesel. Determine of the contribution of the reactive separation process to methanol recovery and biodiesel characteristics are the focus of this study. The transesterification reaction process is carried out in reactive separation equipment, using palm oil as raw material, NaOH, and super base CaO as the catalyst. The results showed that the reactive separation process could recover methanol as much as 55.88% for the reaction process using a NaOH catalyst, and 52.94% for the reaction process using a super base CaO catalyst. The biodiesel characteristics produced to meet the criteria set out in the Indonesian National Standard.

Reactive Separation

An intensified three-step reaction-separation process for the production of bio-jet diesel from tryglycerides and petro-diesel mixtures is proposed. The intensified reaction-separation process considers three sequentially connected sections: (1) a triglyceride hydrolysis section with a catalytic heterogeneous reactor, which is used to convert the triglycerides of the vegetable oils into the resultant fatty acids. The separation of the pure fatty acid from glycerol and water is performed by a three-phase flash drum and two conventional distillation columns; (2) a co-hydrotreating section with a reactive distillation column used to perform simultaneously the deep hydrodesulphurisation (HDS) of petro-diesel and the hydrodeoxigenation (HDO), decarbonylation and decarboxylation of the fatty acids; and (3) an isomerization-cracking section with a hydrogenation catalytic reactor coupled with a two-phase flash drum is used to produce bio-jet diesel with the suitable fuel features required by the international standards. Intensive simulations were carried out and the effect of several operating variables of the three sections (triglyceride-water feed ratio, oleic acid-petro-diesel feed ratio, hydrogen consumption) on the global intensified process was studied and the optimal operating conditions of the intensified process for the production of bio-jet diesel were achieved.
