The refining of biodiesel by adsorption over silica gel was assessed. Silica gel samples were used for the adsorption of glycerol and monoglycerides. Room-temperature isotherms for the adsorption of glycerol were measured ...

In this paper a simple biodiesel purification method consisting of one single stage treatment with silica as adsorbent is described. The presented method seems a solution for biodiesel refining saving water, money and ...

Exploring new renewable resources for energy needs has been gaining great importance in recent years due to mounting crude oil prices, an irrevocable decrease in oil reserves, and increasing environmental degradation. ...

A solar-bio-powered refining concept has been developed to establish sustainable lignocellulosic biodiesel production. The refining concept applies a combined hydrolysis process without detoxification to release sugars ...
