Choosing Plants Produce Oils Fats


Because of the characteristics of each of the fatty oils of different plants, for commercial biofuel production plants should be selected oil-producing fat that is most appropriate. Standard quality requirements for biodiesel, for example, the values of quality parameters are like the devil numbers, iodine numbers, and more haze point is determined by the fatty acids composition of the raw materials used. This occurred because the demon figure, iodine number, and point the fog biodiesel is essentially a kind of net number of similar properties in the methyl esters of fatty acids that make up biodiesel. As such, data characteristics of the fuel of methyl ester fatty acids is a starting point to develop strategies for the selection of raw materials.

As the matter of fact, there are four important things. First, the methyl esters of saturated fatty acids (iodine number = 0), except for caprylic and capric acids methyl ester, high devils framed, but also relatively high melting point [for the methyl esters of pure fatty asa, melting point = pour point, while the fog point of biodiesel is generally about 3-5%]. Secondly, acid-methyl ester of unsaturated fatty acids (iodine large framed) dates to the devil and the much lower melting point than saturated fatty acid esters of picking the same carbon chain. The greater unsaturation (iodine number), the lower the number of demons and melting point. Third, the methyl esters of fatty acids generally have a density value at 40C (except arakhidat ester) and the kinematic viscosity at 40C (except ester caprylic, capric, and erucic) within the range required for biodiesel. Fourth, the methyl ester of oleic acid (iodine number = 85.60) has the optimal properties: the family Malvaceae such as kenaf, okra, roselle, cotton pads, and kepoh) odd fatty acids, ie acids and sterkulat malvalat. Both fatty acids are highly reactive bergugus siklopropenoid and easily polymerizes into the sap when it is hot so that is expected to cause blockage of the nozzle/injector on a diesel engine combustion chamber. Research to ensure this (and mitigate them if necessary) taking place at the Technical Institute of Bandung (ITB), Indonesia.

Related to the presence of unusual fatty acids can be noted, Kaliki castor oil (castor oil) is not a suitable raw material for making biodiesel because it is very viscous oil (viscosity about 10 times the other vegetable oils, or 100 times solar). As a result, the methyl esters of fatty acids having a viscosity range Kaliki far above the allowed ranges for solar. This happens because many Kaliki castor oil fatty acids are also odd, ie risinoleat acid.

I have no doubt that we will be successful in harnessing the sun's energy.
If sunbeams were weapons of war, we would have had solar energy centuries ago.

– Sir George Porter, quoted in The Observer, 26 August 1973

The use of solar energy has not been opened up because the oil industry does not own the sun.

– Ralph Nader, quoted in Linda Botts, ed., Loose Talk, 1980

Thank God men cannot fly, and lay waste the sky as well as the earth.

– Henry David Thoreau

There's so much pollution in the air now that if it weren't for our lungs there'd be no place to put it all.

– Robert Orben

There is a sufficiency in the world for man's need but not for man's greed.

– Mohandas K. Gandhi

Modern technology
Owes ecology
An apology.

Don't blow it - good planets are hard to find.

– Quoted in Time

Nature provides a free lunch, but only if we control our appetites.

– William Ruckelshaus, Business Week, 18 June 1990

I think the environment should be put in the category of our national security. Defense of our resources is just as important as defense abroad. Otherwise what is there to defend?

– Robert Redford, Yosemite National Park dedication, 1985

Your grandchildren will likely find it incredible - or even sinful - that you burned up a gallon of gasoline to fetch a pack of cigarettes!

– Paul MacCready, Jr.

We do not inherit the earth from our ancestors, we borrow it from our children.

When we heal the earth, we heal ourselves.

– David Orr

How long can men thrive between walls of brick, walking on asphalt pavements, breathing the fumes of coal and of oil, growing, working, dying, with hardly a thought of wind, and sky, and fields of grain, seeing only machine-made beauty, the mineral-like quality of life?

– Charles A. Lindbergh, Reader's Digest, November 1939

For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled.

– Richard P. Feynman

Living in the midst of abundance we have the greatest difficulty in seeing that the supply of natural wealth is limited and that the constant increase of population is destined to reduce the American standard of living unless we deal more sanely with our resources.

– W.H. Carothers
