Hi
Brain Rodgers
Gypsym can be used as depolymerizing and delignication agente
for removal of lignin at hiher temperatature , making possivel
cellulose seperation , and hence , sugar and alcohol production

Thank you for the info. I will need to lookup these terms of course. It
does give me more to work with. I do appreciate this.

Thank you too Manick. Yes, my Dad stills gets around on the ranch. We
are grateful that his health is holding and truth is I am kind of
hoping that I look that good when and if I live to be 87 years
Thanks for the
note Manick.
It sounds like you have "been there done that" with cellulose to
sugar to ethanol.
Every technological term in you letter sends me off looking up meanings.
Thank goodness for Google

Hi Brian,
You are fortunate to have walking encyclopedia in your dad. Nurture him well.Yes pressurised SO3 being a gas would mix better than LIQUID, without heavy milling machine.It is just a suggestion. Thanks very much for "been there done that" compliment. It will keep me going in good spirit.
I am new here, but this certainly looks like the place to
be.
I my opinion looking at ethanol strictly from a BTU to create over BTU
available leaves out too many important variables. Even if with

What kind of "residue" is left from wood or these other alternative inputs
to the ethanol production process. Anything of value, like
seedcake from biodiesel production? Anything harmful?

Hello Robert

inputs to the ethanol production process.Anything of value, like

I suggest you read the Wood-Ethanol Report, in the links I posted
before, here:
I used sawdust from Malaysian hardwoods like Meranti. I think any cellulosic material will do. One report states concentrated sulphuric acid and sawdust can also be milled together ( try !:1 ratio initially) into glucose at room temperature, ie 25C. This could be attempted with 2 roll mill set
