Etherification of glycerol with ethanol, both from renewable resources, was studied over heterogeneous catalysts (zeolites of the type BEA, MOR and FAU) and ion-exchange resin Amberlyst 35. The best results Were obtained with zeolite H-Beta (CP 814 Q) with the ratio Si/Al = 25. The conversion of glycerol at the temperature of 200 degrees C was 51,7% at mono-ethyl ethers selectivity of 62% and di- + tri-ethyl ether selectivity of 37,7%. The conversion of glycerol, which was obtained by purification of glycerol phase from MERO production (methyl esters of acids from rape-seed oil), at the same conditions was 50,8%, selectivity to mono-ethers was 71,8% and to di- + triethers 28,1%. Ethers of glycerol have utilization as oxygenate additives to fuels and have positive effect on decreasing particulate matters and carbonyl compounds in exhaust gases. (c) 2017 Elsevier B.V.
