Modified Diesohol Using Distilled Cashew Nut Shell Liquid and Biodiesel

摘要

An emulsifier is generally required to stabilize the EtOH diesel mixture as a result of the difference in polarity of the compounds. This research applied distilled cashew nut shell liquid (DT-CNSL) and biodiesel as additives for modified diesohol. Different proportions of DT-CNSL, diesel, and ethanol were prepared to study the physical and chemical properties together with the action of the emulsifier. The effect of DT-CNSL composition variation on the fuel properties was studied for DE20, DE30, DE50, and DE70. The viscosity and heating value of the fuel blend were related to the proportion of biodiesel and ethanol in the blend. Biodiesel was used as an eumulsifier in this work as a result of the dark color of the blends. The cetane index of DE20 with the content of 1-3% DT-CNSL and 6-20% biodiesel was in the range of 42-52%. With the fuel properties comparable to that of diesel fuel, the proposed blending formulas offer a potential use of DT-CNSL and biodiesel for the modification of diesohol.
