Assalamualaikum dear readers and forumers....yesterday our PM launch the new envo diesel...5% oilpalm and the rest disel...how was it?
read this too my biofuel site www.iznan.com/biofuel |

Waalaikumussalam, Ko btul2 minat ngan biofuel......me too, so why not you give your opinion first, about the future of biofuel in Malaysia.......let say...in term of price.......
Utk pengetahuan ko, Envodiesel nie di kategorikan sbg B5 (5% palm oil, 95% diesel)... |

biodiesel,dari masa penciptaan enjin ader benda...tp masa tuhan hentam manusia ngan masalah ekonomi baru nak research benda-benda cam nie... |

ok let us start the discussion.....first and foremost it is never too late to invent technologie....engineers are born to develope the world,doctors are born to maintaince the development.....Allah gives us taufiq and hidayah to make use the technologie on the right way
Biofuel and biodiesel are two different things. Biofuel is derived mainly from biomass, which come from plant (eg palm oil,soya oil,nuts oil,rape seed oil etc) .While biodiesel is a mix of biofuel and diesel. Biofuel contain most vegetable oil subtances than other chemical subtances. The combination is solely to make the viscosity thinner, so that it can be burned easily during the combustion.

bahasa mudah.. biodiesel lebih likat dan mempunyai complex structure daripada hydrocarbon petroleum (diesel)..dah bersifat suka air..
dalam biodiesel, ada sedikit sebanyak kandungan air.. kandungan air akan menyebabkan no complete combustion, corrosion.. kalau negara sejut, suhu bawah -0oC, fuel will freeze..
kalau guna kandungan tinggi dalam engine, kurang power, complex molekul sukar nak bertindakbalas 100% atau combustion 100%, kalau pakai kat fuel injection, fuel injection cepat rosak.. kalau engine carburetor... mungkin tahan sikit..
kalau nak pakai 100%, kena reka engine baru ler...more robust

yup.. u're rite.. how about gasohol? is it more efficient or less than biodiesel.. and one more thing,
how about the cost of producing the engine and the biodiesel? sometime new invention just can't be
implemented just because we lack of fund and industry resist to accept it.another point to ponder,
the transition process from ordinary engine to biodiesel engine is not something easy to make. if, if
we really want to make this happen, i think all automotive industry and government should be ready
to drenched their head and hand into this matter. after all, we still stuck with LNG usage around
klang valley only. ~ just an opinion~  |

Gasohol ada campuran gasoline (minyak petrol) dengan ethanol (alkohol). Terdapat 2 jenis campuran (E10 (10% ethanol) dan E85 (85% ethanol). Satu satu sebab laiin, ethanol dicampur adalah untuk menganti MTBE, berfungsi untuk mengawal kadar pembakaran. Ethanol lebih baik kerana low toxicity, MTBE is high toxity, boleh mencemar air minum kita.. di US dan Canada diaorang telah ganti dengan guna gasohol.. di Canada, contohnya depa guna E10 (10%). Aku pun hairan, kenapa malaysia tidak mahu bertukar kepada ethanol.. mmm, takut kilang MTBE petronas di Pahang tutup? Almaklumlah, petronas kawal minyak di malaysia..
Biodesel adalah untuk engine diesel.. dan gasohol untuk engine petrol.. MEmang ada perbezaan dari segi pengunaan. Dari segi pembakaran, simple molekul gasohol lagi efficient.
Biodeisel bukan satu pertemuan baru.. dah lama, cuma kurang digemari kerana ia mengeluar asap berlebihan (CO2) dan sukar mencapai 100% combustion (contribute to CO production).
LNG sememangnya lebih baik, terutama untuk sistem pengangkutan awan, macam bas.. patut pakai engine LNG... |

thanks ktman and palister...aku pon share the same points cam korang...cumanya di malaysia kita ni..kurang r and d menyebabkan potensi bahan2 alternatif ini tersekat..almaklumlah negra kita ni kan byk birokarasi dan kroninya...
kalaulah malaysia exploit betul2 sumber alam dia...sure pergantungan malaysia kepada bahan2 api mainstream ni boleh dikurangkan..takdelah rakyat merana menanngung kenaikan kos tranportation....bayangkan kalau bas2 yg pakai enjin disel ni dimodifiedkan utk membolehkan minyak kelapa sawit sebagai biofuel dituang kedalamnya....
modifying is not that hard.....elsbett and atg are both well known companies which provides the equipments to convert diesel engine as biofuel based engine...after conversion...one can use straight vege oil as main fuel....

Btul tu......kat lab tempat aku kerja ade sorang mamat dr Italy sewa satu space utk buat research pasal biodiesel, sample2 dia aku yg test, mmg biodiesel kurang sesuai di negara empat musim sbb kat 4 deg. C pun dah beku. Tp ade formulation yg boleh bg takat beku jd lebih rendah, serendah -16 deg C. Kandungan air yg typical lebih kurang 200 ppm (0.02%) boleh dikurangkan lg dgn proses2 tertentu (control condition) dan kandungan additive yg agak tinggi, dlm erti kata lain, hanya sesuai utk kenderaan, tak sesuai utk powerplant. |

actually dekat US for example dah banyak bus guna biodiesel and proud of it
mmg menjimatkan
dah le wiedly available dekat supermarket ngan kat stesen minyak
the only drawback just bau cam kentang goreng (well..i wont complaint)
tang modified enjin...
kalo kerajaan betul2 nak bangunkan biotech (baper allocation for biotech nih haa?)
apa salahnya some of the spending guna utk R&D
ataupon kasi kat syarikat yg benar2 nak produce enjin2 nih
start utk bas2 dan lori2 besar je dulu laaa... |

tumpang lalu..
wow, korang nie semua mesti terror bab biodiesel testing nih.. :tq: Saya kerja kat lab yg baru nak start testing utk biodiesel. Ade sape2 tau kat mana boleh dapatkan EN method utk Biodiesel?  : |
|
|
|
|
|
|
|
|
|

EN method try cari kat SIRIM Berhad, Shah Alam
Contact:
Sakunthala Devi a/p Manickam
Sales of Standards
Information Resource Centre
Tel: 5544 6112
Fax: 5544 6114
BTW kau kerja lab kat mane?
Aku chemist gak, test utk fuel & lubricant......lab kat Shah Alam, ade gak test biodiesel sikit2 tp guna ASTM standard sbb takde EN.......if you need my help or to share info, pls PM me..... |

Pala hotak lu,
Thanks for the info. ASTM method dah jumpa tapi client2 area sini majority nak test biodiesel using EN method. Tu yang pening sikit tuh.
Saya kerja kat P. gudang. Area testing; palm oil, petroleum/petrochemicals and now developing for biodiesel. |
