[Gasification] Mass vs Volumetric density

[Benjamin Domingo Bof]

Dear Mark; this is an market challenge. In Angatuba where we work , José Policarpo Lopes have an column to distill ethanol. If he produce 96 ethanol receives half part of money than sale "cachaça" (like caribbean "ron") and 45 alcohol is twice volume than 96. Then in money when produce in small scale is impossible to produce at great distillers price. Major Jose Emilio Carlos Lisboa was build an column without technical license, weldings are not under standards, have no license to produce ethanol from ANP and boiler have not pressure test. We came two years ago to work in combined preoduction of ethanol an wood gas but we are discriminated and denied to work in migrant tasks making tools from steel scrap. We claim last friday to ILO (International Labour Organization) because is an political prosecution. Lisboa is Fidel Castro friend and was "imported" an doctor from La Habana givng all facilities.

Dear Doctor Thomas B. Reed,

Thank you for the comment. Is very important to clear concepts separating
hard from soft. Of course energy contents of dry matter is similar, we says
in spanish "cord" ;"stereo" but division is important to clasify uses of
firewood. Soft need less acid to make cellulose than hard then free energy
is better for burn with hard and soft is better not only for chemical
processes but using it for breed cattle. Remenber 14 Kilo of sugar cane
yields one kilo ethanol but 17 kilo is one kilo of meat ;what do you think
what is better? to drink alcohol or eat meat?



Dear Benjamin,

What do you think is better? Eating meat or drinking rum?

It's a tough call!

Mark
