biodiesel and biodiesel crops. In terms of volume, Western Europe will continue to
boost demand for biodiesel, backed by efforts by EU member states to meet the EU’s
target of 10% renewable transport fuel by 2020. Nonetheless, the rate of growth in
biodiesel demand in the following year, the EU will slow down because EU diesel
fuel standards limit the amount of biodiesel that can be blended without the need for
a new fuel mark. North American demand for biodiesel will decline from an
especially strong base year through 2018, but will endure to raise later (Sarkar and
Shimizu 2015; Rezania et al. 2019).
1.1.5 Specifications for Biofuels
Biofuels must meet clear physical and chemical specifications for use in present
ignition engines and for the use of current distribution networks. Next, specifying
accumulation is of particular prominence (Muller and Young 2013; Dahman et al.
2019). The transport biofuels ought to be fluid at ground temperature and atmospheric pressure for gasoline, biodiesel, and sustainable diesel. Gaseous biofuels,
such as hydrogen and methane (biogas), will require modern system technology and
upgraded engines. Biofuels must moreover have the same features that petrochemical fuels would have (Muller and Young 2013).
1.2 Production of Bioethanol
Colorless liquid ethanol (ethyl alcohol [CH3CH2OH]) that has a molecular weight
of 46.7 g/mol is soluble in water, acetone, ammonia, and other organic solvents
(Baeyens et al. 2015). Ethanol can be produced by fermenting sugar, also known as
bioethanol, both chemically from petrochemical sources through ethylene hydration
and naturally through plant biomass. Bioethanol’s most important benefits are that
biomass can be reprocessed, and can possibly provide long-term viable fuel supply
(Amelio et al. 2016; Ibrahim 2013). Bioethanol currently denotes one of the most
prevalent petroleum-based fuel alternatives. Oil is well-thought-out more ecologically pleasant than petroleum-based fuel and can save the planet from pollution
(Ibrahim 2013). The processing cycle of bioethanol depends on the feedstock; it
depends on technologies ranging from the minor conversion of sugar by fermentation to the multi-stage transformation of lignocellulosic biomass into ethanol. Every
industrial fermentation can be divided into three main phases, i.e., upstream
followed by fermentation and downstream processing which is shown in Fig. 1.2.
