PP-66THE INVESTIGATION OF ASPECTS OF TRANSESTERIFICATIONHYDRODYNAMIC DURING BIODIESEL PRODUCTIONZernina I.A., Kazakov D.A., Volkhin V.V.Perm State Technical University, Perm, RussiaBiodiesel is attracting attention as alternative fuel for diesel engines. This fuel isrenewable, non-toxic, biodegradable fuel, and it has low emissions [1]. According tochemical structure biodiesel fuel is a mixture of methyl or ethyl monoesters of fattyacids, produced from oils by transesterification reaction. The system, where thetransesterification occurs, is heterogeneous, reactants are immiscible in each other.The mass transfer of reactants could limit the rate of reaction [2,3]. Enhance of thereagents transfer could intensify the biodiesel production process. The goal of work isto find out the principle aspects of transesterification reaction mechanism and thebehavior of catalyst in the reaction area under various hydrodynamic conditions.The comparison of natural and used frying oils compositions was done. It isshown, that the contents of fatty acids are similar in the natural and used oils.Experimental results showed that used frying oil has high free fatty acid level. Thecomparison of natural and used oil transesterification was done. Experimental datashowed that the compositions of biodiesel from natural and used oil are identical.The study of agitation intensity influence was done. Experimental datademonstrate that the yield of ethers increase over the range of the impeller Reynoldsnumber between 0 and 8,7•10 5 . But there is delay in esters formation at highReynolds number. We suppose that at high turbulence the drop diameter becomessmall. Such drops have no internal circulation, have slow rate of surface renovationand lower mass transfer. Therefore this effect has negative influences ontransesterification. The reaction has an optimum of Reynolds number, which isbetween 6•10 5 and 8,7•10 5 . Investigated optimal condition allow us to reduce thetime of reaction in 1,5 times.References:[1]. Lapuerta M., Armas O., Rodrıguez-Fernandez J.

PP-67STEAM REFORMING OF BIOMASS-DERIVED GLYCEROL ANDETHANOL FOR H 2 PRODUCTIONZiyi Zhong, Shici Duan, Chang JieInstitute of Chemical and Engineering Sciences, A-star, 1 Pesek Road,Jurong Island, Singapore 627833. Zhong_ziyi@ices.a-star.edu.sgBioethanol and biodiesel are two most dominant products from biomass whileglycerol is the major byproduct in biodiesel production. Steam reforming (SR) ofglycerol and ethanol (EtOH) for H 2 production is attractive as the two feedstocks canbe directly converted into H 2 , which is a clean energy carrier [1]. In this investigation,Pt/C(activated carbon) and Rh/ZrO 2 catalysts were prepared by the sonication andthe impregnation method respectively. The Pt/C catalyst was applied to catalyze theSR reaction of glycerol, while the Rh/ZrO 2 catalyst to SR reaction of EtOH. Highcatalytic activities were observed on the two catalysts above 400°C. However, attemperatures below 400°C, a fast deactivation was observed for them due to theaccumulation of surface C-species. A detailed structure-catalytic property relationshipand possible reaction pathways are also discussed.Table 1.
