Title Novel Biodiesel
During
Biodiesel production appr. 10% of glycerol is formed as a by-product that
cannot be utilized directly as a fuel. We have contrived a process in which
the glyceryl moiety is retained and is converted to a fuel component.
We reduce
the molecular mass of biomatter-derived
triglycerides by partial transesterification with esters of low
molecular weight fatty acids, that is,
we exchange long-chain acyl functions of oils/fats for short-chain ones,
resulting in diminished viscosities and cloud points of the partially
modified triglycerides.The process yields a mixture of reduced molecular mass
triglycerides and methyl esters of displaced fatty acids (that is,
Biodiesel), possessing the required values for viscosities, cloud points,
pour points, etc. for Diesel engines. Thus the total enthalpy of biomass
triglycerides can be used up as fuel.
Out of 1000 kgs of purified (99%) repeseed oil (with
an enthalpy of 39.700 Mj) can be derived: Biodiesel Novel Biodiesel Mass (kg) 1.002 1.168* Extra mass (%) 16.5* Enthalpy (Mj) 40.530
43.270* Extra enthalpy (%) 6.8* Heat of combustion (kJ/kg) 40.450
37.050* Viscosity (cSt, Cloud Point (°C) - 2 - 4* Spec. gravity (kg/dm, Cetane no. 54 52* Flash point (°C) 130
130 *
depending on the degree of transesterification/amount of free fatty acids
present or transesterifying species , these values can be varied Owing to
their favourable properties these novel fuels can be utilized for Diesel
engines either neat or in blends with petro-diesels.
As fuels for Diesel engines, heating, etc.
-each
and every atom of the biomass triglyceride is utilized for fuel purposes -at
least 10% extra yield of biofuel from biomatter -by
incorporating the glyceryl moiety no
need to handle a by-product -the
novel fuel can be produced in presently operating BD plants -owing
to fewer reaction steps manufacturing costs are significantly reduced
We have
verified our concepts via laboratory experiments. At present we are working
for scaling up the process.
