i have purchased GC Column for FAME in biodiesel .for preperation of biodiesel sample to inject in gc column i need your help. please i thanks youre helps...
I am also setting up a HP5890GC specifically for biodiesel. What machine are you running? What column, flow rates, etc.. Barry Latham Biodiesel Project...
I am not sure about how good fungus would be but it could work. I know right now there are some companies that are doing what appears to be very good...
Well, I guess the cat (or bug in this case) is out of the bag. While everyone has been excited by algae, fungus are potentially better... why? they don't need...
The Fungus is not a feed stock, but a replacement for the lye catalyst and much of the heat required from what I can see. The discovery was first reported in a...
... Oops, my mistake. Using lipases expressed by whole cells is not new, at all. Heard about that several years ago. Here's one example, from 2005: ...
I work at a power plant and Greenfuels were here for 6 months growing algae, and quite alot of it. They were using plastic tubes apx. 12ft long, it was a nice ...
Dear Group, I'm sure that this has probably been discussed at lenght before; but could someone provide me with some information about commercial production of...
I joined the group because of my curiousity about Biodiesel production as a hobbyist. I see there had been some El Paso members but I haven't seen any activity...
Here at the Complex Carbohydrate Research Center we use an All Tech EC-1 fused silica capillary column (30m x 0.25 mm ID). Having a mass spec for detection, we...
I was hoping Andrew would reveal how he has modified his Appleseed to improve mixing. I'd like to do both...work more efficiently with less methanol and...
Maud and All, Thanks for your interest. The lowest I have run is 14.5%, which I have done 3X and passed each time. 15% makes it pass MUCH easier. Process...
Del, how much methanol total is used in your process? (Amount used in the reaction, plus excess that goes un-recovered? How close to 100 are you able to...
13-14% is how much the reaction needs to go to completion. The reason people use 20-22% is to force the reaction to completion, otherwise you get a lot of...
I'm fairly new to making BD. I've made 7-8 150 liter batches, and some smaller ones. Yesterday, after draining off a 3-5% pre-wash then adding about 30 liters...
Thanks for the detailed info, Andrew. I bought four static mixers from Jim in that original group buy and just haven't had time to figure out how I wanted to...
I am not a chemist, but I do know that adding acid to an emulsion breaks it into its component parts...oil, lye, and water. With a strong acid like sulfuric...
Andrew, Out of 5 gal I recover 3-1/2 from both the BD and the glycerol. I use to not get that much because, I did not bring the heat up as much. I probably...
I am a chemist. In an emulsion, you have water and oil that have mixed. This always happens, but usually at such a small level that you can't see it (oil and...
... Minor correction here - lye + strong acid == salt. 2NaOH + H2SO4 -> Na2SO4 + 2H2O. Substitute K for Na if you used KOH. The acid will break the soap into...
... I got one of each when getting started and just pumped out a 30 gallon tub of water with each. The NT pump (rated 720 GPM) pumped about it's rated speed,...
Del, Help me understand this better, OK? Are you saying that you calculate that you use 5 gallons of excess methanol? In what size of batch? How much...
Maud, Thanks. I replied to a reply to your message. Sorry. If you need more info than I gave, please ask again. Andrew ... just haven't had time to figure...
... and just haven't had time to figure out how I wanted to re-plumb my processor (I generally rearrange it annually.) I'm definitely going to emulate your...
Maud, One more thing... ... just haven't had time to figure out how I wanted to re-plumb my processor (I generally rearrange it annually.) Consider figuring...
That's very helpful, Andrew; thank you! I'm wondering...would it be possible instead of using a bigger pump to use two cheesy HF pumps? That way you could use...
