QuestionAnswer
BUT METHANOL  IS DISADV ... MORE EXPENSIVE THAN METHANE OR OCTANE.
A BIO FUEL IS A FUEL ... MADE FROM RENEWABLE ORGANIC MATERIALS , SUCH AS SUGAR GRAIN, OR VEGETABLE OILS.
BIO FUELS HAVE A CARBON FOOTPRINT BECAUSE ... FERTILISERS AND FUEL ARE USED WHEN THE PLANTS GROWING ENERGY IS REQUIRED TO MANUFACTURE AND TRANSPORT FUEL.
ETHANOL CAN BE MADE BY ... FERMENTATION OF CARBOHYDRATES.
FERMENTATION OF CARBOHYDRATES TO MAKE ETHANOL ... STARCH IS BROKEN DOWN INTO GLUCOSE BY HEATING WITH ACID CATALYST OR ENZYMES FROM SPROUTING BARLEY: (C6H10O5)N + NH20àNC6H1206
SUCROSE IS CONVERTED INTO MIXTURE OF GLUCOSE AND ISOMER FRUCTOSE BY .... ENZYMES IN YEAST -C12H22O11 + H20 à C6H1206 + C6H12O6.
THE FERMENTATION OF BOTH GLUCOSE AND FRUCTOSE MAKES ... DILUTE SOLUTION OF ETHANOL: C6H12O6 à 2C2H5OH + 2CO2.
IN FERMENT OF GLUCOSE AND GLUCOSE ETHANOL HAS TO BE OBTAINED FROM MIXTURE BY ... FRACTIONAL DISTILLATION,
NEEDS ENERGY.
WHY WOULD CAR USING BIO ETHANO TRAVEL SHORTER DISTANCE PER LITRE OF FUEL THAN PETROL... LOWER ENERGY OUTPUT ENERGY OUTPUT OF ETHANOL IS 23KJCM-3 WHICH IS 63% OF PETROL,
SO MUST PETROL IN UK HAS ... 10% ETHANOL.
WHERE CAN YOU GET BETTER BIOFUEL ... FROM SUGAR,
2 STAGE TO CONVERT FRUCTOSE INTO ... . 2,5,DIMETHYLFURAN(DMF)C6H80. DMF
DMF ADVANTAGE OVER PETROL ... HAS HIGHER ENERGY DENSITY.
DMF DOESN'T REQUIRE AN ENERGY INTENSIVE DISTILLATION PROCESS COZ... IT IS INSOLUBLE IN WATER, ABSORB WATER IT CAN BE SEPARATED EASILY FORM AN AQUEOUS SOLUTION
IN TERMS OF CARBON, ATOM ECONOMY OF DMF IS... OVER 75%.
WHAT IS ENERGY DENSITY? IT’S ... THE ENERGY RELEASED PER UNIT VOLUME OF THE FUEL. UNITS ARE KJCM-3 OR MJDM-1.
OTHER RESEARCHERS FOUND WAY TO MAKE DMF FROM... GLUCOSE ,DMF CAN BE BIO FUEL OF FUTURE J.
VEG OILS ARE ESTERS OF... PROPANE -1,2,3-TRIOL & UNSATURATED FATTY ACIDS CONTAINING 18 CARBON ATOMS & 1+ C=C BOND.
A VEG OILS CONVERTED INTO BIODISEL BY... MIXING WITH METHANOL AND ACID CATALYST TRANSESTERIFICATION REACTION OCCURS.
EXAMPLE OF TRANSEATSERFICATION REACTION OCCURS... MIXING METHANOL
TRANSESTERIFICATION REACTION IS A REACTION BETWEEN ... AN ESTER AND ALCOHOL THAT PRODUCES A DIFF ESTER AND DIFF ALCOHOL.
METHYL ESTER & UNSATURATED ACIDS & FREE PROPANE-1,2,3-TRIOL... THESE METHYL ESTER HAVE SIMILAR COMBUSTION PROPERTIES TO DIESEL FROM PETROLEUM.
CERTAIN ALGAE YEILD OF OIL .. .HIGH
ALGE YEILD OF OIL CAN BE CONVERTED TO ... BIO DIESEL.
PLAN FOR ALGEA IS TO ... GROW ALGAE AT AREAS OF HIGH SUNSHINE & IN PONDS IN SEWAGE WORKS
