Process of Fermentation Video Lecture | Chemical Technology - Chemical Engineering

welcome to file views Academy this video
is made available and part of the
biofuels education project funded by the
National Science Foundation and the US
Department of Agriculture in this video
we want to illustrate the process of
fermentation the feedstock is delivered
to the feed handling area for storage
and size reduction in the very first
step since the efficiency of the
fermentation is dependent on the
particle size of fish stocks then the
feed stock is then to a pretreatment
reactor there are many ways to pretreat
the feed stock by using steam hot water
a sedan decline in this video we present
the combination of steam and acid
pretreatment which have been suggested
to promote hydrolysis big-nosed elinoz
is hydrolyzed into stella knows lignin
and hemicellulose in the present of
steam and ethics
then the pretreated feedstock is
delivered into a hydrolysis reactor the
material must be made less acidic for
enzymes and organism to function
optimally in the hydrolyzed aid
environment first the Longfellow chain
is decomposed by n2 glock knees into
short solution then a short solution is
decomposed by Expo glucan ease into
cellobiose fragments
finally the cellobiose fragments is the
compulsive I'd better glucose days this
is the entire process of hydrolyzing
cellulose into glucose together with
microorganism nutrient and ng form the
glucose is delivered into fermentation
reactor five copper and six carbon sugar
can be formed separately here will only
present the fermentation of six carbon
sugar the six carbon sugar fermentation
converts
one mole of glucose into 2 mole of
ethanol in a 2 mole of carbon dioxide in
a presence of East in addition to water
and ethanol the fermented fruit contains
a number of other materials such as
microbial biomass filter all your
volunteer company th and lignin the
Bruce is further processed by
distillation finally the pure as no is
stored
some references used in generating the
videos are listed here the members of
