Biodiesel Rulez!!! [ARCHIVED]

[kontrabulatekid]

Mayroon factory outlet store ang Chemrez, they sell BioActiv for P74/500mL and P1,240/20L. Petron sells BioActiv (green) for P74/500mL and Flying V sells BioActiv (blue) for P64/500mL. Flying V appears to buy BioActiv wholesale and they re-bottle it.

ok thanks po boss. so cheapest so far is flying v, nabibili ko yun 1liter bottle nila ng biodiesel at P125 each.

if flying v buys and repacks, bat kaya iba yun kulay ng bio-diesel nila?

quick question lang gurus. i use a mixture of diesel and paraffin on the chain of my bike for lubrication. im thinking of trying out bio-diesel to substitute diesel kasi supposedly biodiesel has better lubricating properties right?

tia!

Chemrez said they supply Flying V with "Blue BioActiv" as they know it will be re-bottled and to differentiate it. Color lang daw ang pagkaka-iba.

Its more expensive when you buy CME & mix it yourself (compared to buying it pre-blended at Flying V) but this way you get better control of the percentage (just in-case nagtitipid ang Flying V.)

Biodiesel has good lubricating properties but remember it also has good solvency -- cleaning properties. At higher percentages, this alarms me. If it can eat rubber components, clean the fuel system & combustion chamber -- baka sumubro ang linis at mag loose compression ang makina.

Kaya ako, "keep testing & observing" 0.5% CME muna habang pwede. Nakakatipid pa ako dahil nasukat ko na ng ilang beses, sa 1% CME ang "fuel savings" at "emission reduction" ay pareho lang.

pwede naman, just don't get the bd on your bike tyres. medyo matapas bd compared to diesel, it willruin your tyres..lalambot yung rubber...

Its coloring. Chemrez also produces coloring solutions... which is used also to differentiate gasoline/diesel products from each other. They sell their coloring solution to the different fuel companies.

*biogas.works - thanks for the info sir! i've been using biodiesel for about a year now and have only good things to say about it. although ngayong bagong overhaul ang engine ko, aminado ako i can't see much effect sa hatak ng car kasi lumakas talaga because of the overhaul. pero sa emissions, wow, galeng!

here are some average stats i've gathered since i've used biodiesel:

before overhaul:
before using bd: 6kms/liter
on bd: 8kms/liter

after overhaul:
no bd/break-in period: 10.25km/liter city
on bd: 14.25km/liter hiway
on bd: 12.5km/liter city

yung city driving ko is based on my usual rosario-ortigas center route. hiway is based on pasig-nasugbu-pasig route. all stats are at 1% cme except for the 5% blend i did on my first time with bd.

i'll try 0.5% as you recommend and see what happens. thanks again!

*rsnald - thanks sir, subukan ko later when i get home!

tnx for the info sir! natawa lang ako kasi kapit bahay ko ang mga lao of d&l/chemrez pero di ko naisip magtanong when i see them hehe.

Last data from the PCRDF (Philippine Coconut Research and Development Foundation) as published in The Philippine Journal of COCONUT STUDIES Vol.XXVIII Number 2. Naka 100,000 km na sila sa C240 Isuzu Diesel engine using 100%CME. Some of their findings:

Actual road test mileage: CME 7.15 km/l, diesel 8.10 km/l CITY DRIVING. CME 8.99 km/l, 9.64 km/l COUNTRY DRIVING. A 3.5% difference in thermal efficiency as fossil diesel has higher BTU content and with regards to Fuel Consumption Index, a difference of 14.15%. Exhaust gas emissions. Carbon monoxide 335ppm for diesel, 282 for CME. 23K for diesel and 33K ppm CME for CO2 emission. There are no adverse effects on the engine at B100!

question ulit mga gurus. aside from lubricity, di ko alam difference ng diesel 1 and diesel 2 (kerosene & diesel). i've been reading some biodiesel literature on the internet and ngayon iniisip ko if it would it be feasible to use kerosene + biodiesel as a substitute fuel blend for diesel engines?

sori umiral na naman kacheapan. i wouldn't really try it until some reputable company recommends it though. just a thought.

Dr. Kamiya, in quoting an EROEI of 3:1, you generalize using the term "biodiesel", when in fact not all biodiesels are not created equal.

You quote the low EROEI of biofuels to conclude they are not viable alternatives to fossil fuels. That's the line the oil companies keep repeating to us. The fact is, no technology (solar, wind, etc) can match fossil fuels in terms of EROEI. So we should just give up and stick to buying and using fossil fuels, right?

But what about the effects on our environment?

Quoting here an article from the Inquirer, http://opinion.inquirer.net/inquirer...ticle_id=48746:

"Taking the opposite tack is a lobby group funded by one of the world’s largest oil companies. The Guardian UK reported that the American Enterprise Institute, an ExxonMobil-funded think tank with close links to the Bush administration, offered scientists and economists $10,000 each to undermine the IPCC report.

Climate scientists said the move was an attempt to cast doubt over the “overwhelming scientific evidence” on global warming."

Makes me really sick.

Not to take the side of big petrol here, but a low EROEI also means negative effects on our environment. How much land mass will have to be sacrificed for productive biodiesel production? In addition to, or in place of crop-crowing land?

I'd rather see solar or hydropower-based hydrogen extraction facilities. Unlike biodiesel production, these will take up much less space, not take up more agrable land, and will be just as renewable. Honda's hydroelectric hydrogen extraction plant in southern Japan was particularly impressive. Other means of hydro-power like ocean-going wave motion based generators are also interesting.

Perhaps it's just my personal tastes and by no means have I wanted to take the side of big petroleum against renewable energy, but with conservationists crying left and right about losing "wild land" to too much agriculture and urban crawl, i'd rather not see bio-fuels take off, unless they are done as a means of reducing waste (farm-based bio-fuels). Crop-based fuels i choose not to buy into, until someone can prove they are a more efficient use of land than for growing edible crops.

You're right, I quoted 3:1, to represent the best of biodiesel. Coconuts can get thereabouts, but corn-based biodiesels are at a piffling 1.5:1 to 1.9:1. If I wanted to just bash biodiesel I would have quoted as low as 1.3:1, to represent early corn-based biodiesel products.
