Evaluation of properties of the biodiesel synthesised from waste fish fat/oil in seafood processing facilities and ability of biodiesel blending with diesel fuel satisfying Vietnamese National Standards

Abstract

Biodiesel is considered as one of the ideal fuels to replace
traditional fossil fuel sources. This report exhibited
the role of biodiesel through the mixing ability of
biodiesel synthesised from oil/fat of fish waste in seafood
processing facilities into diesel satisfying technical and
environmental indicators according to TCVN 5689:2013
and QCVN 1:2015/BKHCN for diesel fuels and biofuels.
The result showed that oil/fat of fish waste recovered
from catfish processing is a potential source for biodiesel
production. The result of examining the properties of the
original fuel B0 (diesel), B100, and the blending samples
B2, B4, B6, B8, B10, B12 revealed that increasing
mixing rates will improve the burning properties of
fuels, in particular dramatically increase the cetane
number, which is an important indicator that increases
the autoinflammation of fuel, keeps running smoothly
and its exhaust contains fewer hazardous components.
The blending of biodiesel significantly reduced the
sulfur content, which is an important environmental
target relating to the emission standards, needs special
attention in the context of Vietnam is following the Euro
5 emission standards. Other standards relating to fuel
storage also showed that the blending with biodiesel
improved fire safety as well as the use of fuel in lowtemperature conditions.
