[Gasification] RENEWABLE ENERGY FOR RURAL PRODUCER

[Benjamin Domingo Bof]

RENEWABLE ENERGY FOR  RURAL PRODUCER 
  Present situation of
renewable fuels The environmental increase of price of petroleum and
considerations have made appear the interest by alternatives to
fossil fuels. A fuel with a tradition of thirty years in Brazil is
the ethanol that arose in the first rises of price of petroleum and
before the insufficiency of then Brazil from autoabastecer itself.
Automobiles to pure ethanol were constructed and had times of height
and declination arriving itself to propose the suppression of the
production of such. At the moment with the fuel injection the
models "flex/fuel" they allow to consume a combustible mixture from
zero to one hundred percent of ethanol. In 1937 the Faculty of
Agronomy of the UBA made tests with the different proportions from
gasoline and ethanol. Also a gasogene to vegetal coal was
constructed.
MECHANICAL PRESS TO EXTRACT VEGETAL OIL
In July of 2003 we concurred to one "fazenda" in the Rodovia
Castello Branco km 132 where it worked a press to extract sunflower
oil and a Peugeot light truck made in Argentina that was without
working by mechanical flaws caused by the vegetal oil use without
desparafinar. The press era of homemade construction, basically
palier with means of suspension welded in form of spiral within a
cage with narrow grooves. Animated we bought a reducer 50:1 and in
Angatuba we asked the cost of the seed which us deparó a surprise.
With three kilos of seeds a liter of vegetal oil is obtained that if
it is sold in the commerce reaches to buy two liters of oil gas. The
only then option was the cotton seed whose expeler it is a forage
advantageous for the milk production. We remembered of "Viti"
Passamani, a Pampas blacksmith of Hell, Chaco the education of
manufacture of indented pinions to use chains of rollers to transmit
movements. This allows that with a agujereadora it is possible to be
made crowns and pinions of all size in homemade form in any
blacksmith shop of campaign.
HOMEMADE ETHANOL DISTILLATION
The 19 of November of 1991 we published in the
Press "Autosuficiencia Energética" showing engineer Manuel Vassallo
and his distilling column in the city of Currents State Capital of
the same name. We counted this I also articulate to a settler of
beautiful Vista in Currents Mr. Karlen who told us that in 1943 when
the fuel shortage because of the war "popero" made they themselves
alcohol for the motor; with originating molasses of the sugar talent
of Villa Ocampo in the other margin of Paraná.Llegadosen 1996 to
Beautiful union laughed, Uruguay by a sign of homemade ethanol
production we tried alcohol to burn of Tucumán and Uruguayan
gasoline in a motor Argentine Villa of 4.5 HP to water five
greenhouses with satisfactory result. It gave a strong
scent "carucita". In Brazil we could notice that the combustible
ethanol use as of motors takes one long tradition. Recently we took
contact with the project from Unicamp of ethanol production in micro
distilleries in a system of minimum use of energy of petroleum to
obtain milk, meat and combustible ethanol. Donkeys are used to
surround the cane and the propose extension for a familiar operation
is of fifteen hectares. One hundred fifty liters of milk and one
hundred of combustible ethanol are produced. The bagasse remainder
of the milling of the cane is used like forage and that in our
investigations we obtained a system that uses a solution of
hidróxido of calcium for "hidrolizar" the bagasse in order to obtain
a greater conversion of the cellulose. Technology sufficient exists
to produce ethanol in any scale.
BIOMASS GASIFICATION
The 21 of June of 1994 we published in LA PRENSA ; "Energía
electrica a partir de carbon vegetal" showing a gasogene that by
means of vegetal coal drove a motor F100 V8 292 connection to a
generator ELT. We continued the investigations in Brazil and at the
moment we are determining the thermal values involved in the gas
obtaining "reforming" of the limestone stone. A meter matting of
firewood of eucaliptus calcines one ton of limestone that contains a
45 percent of carbon dioxide. This gas to high
temperature "recarbura" when happening through vegetal coal
obtaining a gas of greater content of carbon monoxide that
combustiona in the interior of the motor. With the injection of
steam to high temperature the content of hydrogen of the gas is
increased. Recently a gasificador was published in YouTube done of
mud and you marinate following the lineamientos of the antiquity of
the furnaces of mineral reduction and of the high furnaces. With
some native hours of manual labor and elements one is able to
construct a gasificador to move any stationary motor of the
agricultural activities
MODIFYING MOTOR
Ours it defied present is to act on the motor. Many tests already
were done as the motor to high temperatures is the Deutz motor with
Elsbett system to consume vegetal oil without treatment working.
Recently we have discovered that the diesel engine can
consume "alcohol of quemar" of Tucumán if it is vaporized in
the "dual-fuel admission manifold working ". Bond to say that by the
admission it receives a mixture of air and gas and the liquid spark
is provided by the diesel oil injection in a fifteen percent. The
old Lanz-Pampa Tractor made by IAME in Argentina was prepared to use
firewood in gasogene and oil of refrigerator in the injection. This
does about seventy years. There is nothing no new under the sun.
