Cool:) i like that music actually :D it makes me want to create
so is this like the fat from cooking like grease or am i misunderstanding?
I wonder if this process will works with used motor oil? anyone know anything about this?
No, it doesn't. <br />
&nbsp;why not?
making biodiesel is the transesterification of organic fats.&nbsp; my understanding is that the chemistry of petroleum is simply too different.&nbsp; i don't think it contains any glycerides to be removed (which is what is removed from organic fat to make it biodisel).&nbsp; also, the &quot;kerosene-esque&quot; fuels (diesel, jet fuel, etc.) have already been removed from petroleum crude before you get the motor oil.&nbsp; motor oil, could be considered to be a by-product of that process (although it's not really that simple).<br /> that's not to say that motor oil can't be burned, but it's nasty stuff that will only burn cleanly under very high heat, if ever.&nbsp; motor oil is best recycled through proper channels.&nbsp; i've seen it used to start a bonfire once.&nbsp; it worked, but it was smokey and stinky and left residue on the ground afterward that is probably still seeping into the water-table to this day.&nbsp; i've also known people that used it in a home-made diesel of sorts.&nbsp; the process, as described to me, is extremely dangerous to the individual, as well as almost certainly bad for the engine it was used in.&nbsp; furthermore, i have no doubt that such a fuel produces far more pollutants than standard diesel, let alone ULSD and biodiesel.<br />
Hey try to educate yourself before you speak. I know many folks using used motor oil called black diesel.. look it up on google.<br>used motor oil is burned in ships, thats right cruise ships the ones people vacation on.. and also on freight ships. so its legal and non harmful for them to burn it.. guess what its going in my truck...<br>the guys that do it around my part of town blend it with gasoline to get the viscosity as close as possible to diesel,, and then on 8 gallons of used filtered and gas blended &quot;black diesel&quot; we add 2 gallons of reg diesel so its 80% black diesel...<br>enjoy the lesson !!!
I have used motor oil (filtered through a 5 micron filter) and also ATF straight into the filler with no problem. I have a Land Rover 110 1984 with a 1996 Isuzu 2.8 tdi engine. The low viscosity allows usage in this way. 'Bess' Also loves bio diesel, in fact runs better than DERV, but because the viscosity is much higher and contains Glycol or Glycerin, it needs to be seperated for Winter use. I have a fuel filter rap around heater than enables WVO (filtered through an old satellite dish) to be used in the Summer without refinement. It depends how sensitve your engine is. Only try unrefined WVO if you are sure your engine will take it. <br>
So.. please forgive the ignorance, but can this same basic process be used with WVO to create biodiesel? I know it was mentioned that the animal fat is more calorific than that of VO, but does that simply mean that the reaction with occur faster, or that more steps must be taken? Thanks!
Great vid; non-existent Instructable. Me explain: What does the unversed user do with the byproduct/precipitate at the bottom of the 'reactor' (glycerin, I presume)? Is s/he to assume it just gets 'mixed in' with the fuel? (Can s/he send you his/her repair bills? :-)) Where does one procure the "hydroxide of potassium (potassium hydroxide/lye?), and where might one avail him/herself of the requisite methanol? Can these items be procured WITHOUT ending up on a terrorist watch list? Assuming your goal is to provide actual, useful information, these are the kinds of questions people will have. :-)
you can get potassium hydroxide and methanol with out raising questions. One is used in soap making the other is used for painting/cleaning.
Methanol is also used as race car fuel.
iso-heet, that you see at the autozone, is methanol. i think you can make your own methanol from corn. same for making grain alcohol but use a different process. worth researching into.
Sorry - you kids need 2 do yer research - &quot;Iso-Heet&quot; is just that - ISOPROPYL Alcohol - NOT Methanol - use the yellow bottle (Heet) not the red bottle (ISO)...<br />geez.&nbsp; also - better look into the fact that KOH (potassium hydroxide) &amp; methanol produces potassium methoxide - not what you want - you want Sodium Methoxide , so try using Sodium Hydroxide (Red Devil Lye) instead - research is pending on the use of KOH (potassium hydroxide) &amp; Ethanol (BOTH&nbsp;&quot;enviro-friendly&quot; and user produceable chemicals) to make Potassium Ethoxide for the biodiesel esterfication process... just my 2 cents<br />
Pretty certain Iso-heet is isopropyl. Very certain, in fact. And you can make ethanol from corn, not methanol. The two alcohols are very different. cheers, -DMC
someone told me it was methanol in the isoheet. as for ethanol, i know it from corn, but i think if you change the process differently, you can get methanol. I ll look into it. also you can get methanol from wood by gasifying it.(wood gas?) put a couple wood chip in a soup can and put it on top of a electric stove, punch a small hole in the top, and wood gas or methaol will come out the top. yes, this isn't energy effiecent in methanol making. I also remembering reading that termite farts methanol too.
Ahem. The point, of course, was that none of this information was available in the 'Instructable.' If I hadn't already known the processes and chemistry involved in converting animal fat into biofuel, I'd have come away from watching this video knowing absolutely nothing about how to actually MAKE biolfuel. (I ASSUME, of course, that teaching such was the whole point of the video. :-) ) My post, then, wasn't for MY edification, but for that of the AUTHOR. Otherwise, and like I said, the vid was GREAT (for people who already know what they're doing).
I was thinking about the best way to get oil for biodiesel and I thought of Milfoil. It grows very quickly and is not wanted for anything because it is an invasive spices. I was wondering if anyone knew the oil content of milfoil. If it even has 15% it would be great. I know of a lake where they have two huge machines designed to cut milfoil from the lake so it would be very easy to get. If you know anything about this let me know.
If you get grease and/or oil from animals from restaurants, can you skip the cooking process? A lot of restaurants give their grease and oil to people for free because it keeps them from paying a fee to dispose of it and after they can't use it to cook anymore they feel it makes better business sense to give it away for free instead of paying the disposal fee but can it be used in the making of bio diesel? If so does it have to be cooked again or can I just use it as is. If I go on that trail, can I follow the recipe from the video or will I have to follow a different recipe.
Do you still need to wash the biodiesel if this process is used?
Washing sometimes makes worse the situation. The soap is falling by itself after a few hours. Important is content of the lye. PH should be around 6. The fuel is more calorific from the lard than from SVO or WVO...
Thankx
Are you going to post an Instructable on this? Because there are definetly enough instructions for one. Nice job though!
