Commercial edible grade canola oil (mw: 876.6 g/mol) was
obtained from market and was used without purification. Methanol (Merck
reagent of 99.9% purity) was used as received. CaCO3
(Daejung Chemicals
extra pure) was used after calcination. Dolomite was obtained from Rizalar Mosaic Industry and Trade Limited
Company located in Gebze/Kocaeli, Turkey. The origin of dolomite
was Marmara Island of Turkey. Dolomite was used after calcination. The chemical composition of dolomite was 23.50% Ca,
12.07% Mg, 63.02% CO2and 1.41% other components[18].
CaCO3was calcined at 840C for 3 h. After calcination, the product CaO produced according to reaction(1)was pulverized in the
porcelain mortar and CaO powder was calcined again at 840C for
60 min to prevent absorption of CO2and humidity during the pulverization process. Then, CaO was cooled to the room temperature
in a desiccator under vacuum. The same calcination procedure was
applied also for dolomite according to reaction(2)
