Interesting. Puede pala yung pinag-prituhan ng tilapia, fishball, french-fries, at iba pa.

pwedeng pwede talaga. eto lang basic requirements.

- cheesecloth or any very fine mesh cloth, say, "katsa", yung sako ng harina. you'll need that to filter the used-cooking oil
- absolute methanol= mabibili sa mga old school botika or pharmacy's. meron din sa mga laboratory chemical suppliers like alyson or yana. Di pwede yung rubbing alcohol (isopropyl alcohol). Yung ethanol pwede din pero absolute ethanol din kailangan= hindi absolute vodka ha :D

- lye (sodium hydroxide) = catalyst for the reaction.
- a cooking pot that can be heated to about 50-60C. if you want to read the exact temperature, just buy a thermometer.

- maybe some muriatic acid = for refining and neutralizing the excess lye.
- lots of patience and your supply of used cooking oil.

rsnald: nag try ka na ba diy na BD? ano naging experiemce mo?

[falken]

IMO, kailangan siguro humingi sa mga fastfood chains ng used cooking oil if you want to try this, pag cooking oil sa bahay kulang na kulang yan.

pwede ba yung coconut oil?

[colt45]

Puede yata ang coconut oil. I think Senbel is using coconut oil. Sa bandang Quezon yata ang planta nila where there are lots of coconut. I am not sure though kung easily available yung iba pang ingredients like methanol, lye, etc.

[chase]

methanol n lye are commonly available. no need for licenses i think...

rsnald: nag try ka na ba diy na BD? ano naging experiemce mo?

di pa pre, pero madali lang gawin basta you have the right materials= pinaka importante yung methanol. it must be water free.
sa mga nagawa namin sa lab, matagal lang hihintayin mo para humiwalay yung by-products ng reaction pag gamit mo crude oil, which will be the case pag gumamit ka ng used-cooking oil. after "cooking" kasi, malabo yung makukuha mong CME. you'll have to leave it standing for 2 days or more siguro para luminaw yun. then you just decant the upper layer throw away the lower layer. glycerol at and unreacted material yung nasa ilalim.
yung mga DIY biodiesel, malamang hindi pasok sa specs ng PNS. pero wat da heck, half liter lang naman gagamitin mo per 50 liter full tank. The ASTM specs for biodiesel was meant for using biodiesel that will be used as 100% fuel.

pwede ba yung coconut oil?

coconut oil talaga ang gamit sa paggawa ng local biodiesel marketed by senbel and chemrez. kaya nga nag tawag ng iba sa local biodiesel CME = coconut methyl ester. pero kahit na anong vegetable or animal oil (wag lang petroleum oil shempre), pwede panggawa ng biodiesel. mag-iiba lang sa yield at fuel properties yan. the good news is, meron na yatang finding na ang biodiesel made from coco oil yields a fuel with a relatively high cetane index compared to using soya oil or rape seed for example.

rsnald: experiment na ito! so methanol and lye saan pwede bilin?

[Mojo]

daba pwede direcho icarga ang straight vegetable oil or SVO walang process process? kung ganun pwede ba icarga ang minola sa diesel engine ehehehhe. or may parang kit pa kailangan kabit sa engine?

[Skywalker]

Straight vegetable oil or SVO, may nakasubok na ba? May modification lang sa fuel system like additional fuel tank, heaters, etc. pero at least hindi na kailangang maghalo ng kung anu-anong chemical.

Meron bang nabibiling used oil sa mga fastfood stores? O kaya sa nagtitinda ng fishball

[garyq]

pwede SVO or even WVO. On WVO you have to check for water content in the oil and also filter for impurities. Also properly heated WVO should go into your diesel engine and cross contamination should be avoided with diesel fuel. See frybrid.com, greasecar.com, etc. Pag umabot sa 45/liter ang diesel I will definitely use alternative fuel.

subukan mo sa alyson pre, sila lang alam kong chemical supply house na nagbebenta ng tingi. 712-2323, 712-2324. sa may Mayon avenue sila. or subukan mo din magtanong sa mercury. mas mahal ng lang siguro dun.
kakalanganin mo ng panghalo sa reactor mo... kung meron ka variable speed hand drill, at saka yung parang pang bate ng itlog, isalpak mo na lang dun sa hand drill. kelangan kasi nahahalo ng mabuti yung methanol + coco oil mixture + catalyst, almost 1 hr mo din hahaluin yun at 50-60C. kung wala kang thermometer.."hipo-meter" na lang ... hipuin mo yung cooking pot, kung mainit init na ayos na yun. di na kailangan pakuluin. WARNING: do not do this on a gas range or with open flame. use an electric stove. kung meron kang lumang electric stove.. yung northern hill ba yun, pwede na yun. set mo sa low heat lang and do it in a well ventillated area, in your garage maybe. very flammable ang methanol pre.
kung di ka naman nagmamadali, pwede rin yata wag na initin, pero mas matagal lang reaction, saka kailangan din haluin. mga isang araw mong hahaluin yun pre, at di lang basta halo...kailangan halung-halo. sa umpisa kasi, hindi compatible yung methanol sa coco oil, you have to beat it together to mix well and get into intimate contact

goodluck pre! balitaan mo ako kung ano result.

[quiksie]

calling chemists yayaman tayo dito hehe.
Baka mabalitaan nalang natin ang jollibee ay nagbebenta na ng biodiesel

[garyq]

guinea pig ako ha! research din ako muna.

[colt45]

From what i've seen sa internet, madali lang ang fabrication nung mga tank at stirrer. Excited ako dito ah! Biruin mo, you produce your own fuel. Puede ka pa mag-recycle. Di ba ang by-product niyan ay soap?

[rsnald]

guinea pig ako ha! research din ako muna.

pre, ito muna subukan mo...yung mini-test reactor.

http://journeytoforever.org/biodiesel_processor7.html

para naman di masayang experiment mo. nga pala, nakalimutan ko banggitin, kelangan mo din ng timbangan. yung mini-weight scale na nabibili sa shopwise, pwede na yun. importate yung ratio ng materyales pre. basahin mo na lang sa journeytoforever. madami kang mapupulot dyan, yung iba nga lang, merong ok, meron din hindi ma verify pag ginawa namin sa lab.

ADDITIONAL PRECAUTION LANG: minimize skin contact with methanol. overdose of methanol in the bloodstream causes blindness.
yung lye (chemical name - sodium hydroxide, or caustic soda flakes/solution), hugasan mo agad kung malagyan ka sa kamay or any part of your clothing... corrosive yan. yan ang active component ng liquid sosa- yung binubuhos sa CR or lababo pag barado.

Good luck pre! ano brand name gagamitin mo pag successful ka na? garystrol? :twak:

[Mojo]

nabasa ko rin sa internet,

na tendency ang Bio diesel/SOV maag corrode ng injector pump, nag nag gugum din, kaya kailangan i research to mabuti.

Sana mag labas ang DOST ng Research ng tamang paraan ng pag gawa para maiwasan ang corrosion at gumming sa engine

[garyq]

mojo: better if you mix BD with regular diesel. Pag 100% BD baka maka affect sa rubber seals ng engine.

rsnald: experiment lang ito. Baka magalit Senbel sa akin He!he!he! Sa ngayon ideas lang ito. Pag umabot ng 45/ltr ang diesel....ummmhhh

[nugundam93]

just to dig this one up...i came across this: http://www.pocuk.com/forums/viewtopic.php?t=32207

am thinking of doing the same din eh...mahal na diesel
