So I am planning on making my own bio fuel here in the next couple weeks but I have a few questions. I am going with the appleseed approach. First do you need to filter the bio diesel and where do I put the filter or filters in my system. Second where can I find methanol and lye? Then I was wondering if someone could explain the titration process a little better that would be great. I have done a lot of titration in my chemistry labs but I am not 100% clear on what needs to be done here. Thanks in advance.
