Help TPE Biofuels: Can you help me? Thank you

[Zephyrus]

Hello.

Can you help me with my VSEs, alternative fuels?



thank you ^^

e then wondered if biofuels were really that profitable, that at first glance, by making the balance equation of rapeseed (vegetable oil) and comparing it to that of Octane (component of gasoline); we see that rapeseed releases three times more CO2 during its combustion.

Why ? In fact, when we talk about biofuels and the fact that they "emit" less CO2, the problem does not only concern their combustion but the behavior on the whole of life, in fact plants consume CO2 during their life. life (photosynthesis) and their combustion as a biofuel will release CO2 but during this combustion much less CO2 than during the combustion of Octane.

well there you say anything and its opposite!

there are 2 types of engine on earth: petrol and diesel
you forget the main interest of biofuels: remove the oil that makes SP95 (tm) and diesel (tm) because it is a fossil NRJ = liquid concentration of a millennial CO2 storage.
the mineral is a fossil NRJ (like uranium) = mineral oil or rock oil ...

However, BIOfuel comes from BIOmass: the plant that grows, absorbs CO2 (fossil or not) and rejects during its combustion of non-fossil CO2 because it is a vegetable, not a mineral!
that's why it is renewable: it uses its previous release of CO2 to regenerate!
the same cannot be said of petroleum because it is a fossil, it takes millennia to accomplish this same cycle ...




the oil is not a substitute fuel because it appeared first, the diesel engine was invented for that, with vegetable oil therefore revise your dictionary ...
the tankers arrived by offering an alternative fuel = petroleum.
because at the time rapeseed oil cost much more than today, which is no longer the case !!

ditto for petrol, in 1st it was the alcohol engine.

like alcohol lamp, oil lamp preceded the kerosene lamp, etc ...

So review your basics before you start your TPE! -)

[gaya]

pike not my subject you fé kwa la !!!

[Christophe]

? Are there exclusivity in the subject of TPE ????

[jonule]

+ it is original as a research avenue ... while everything is said on the subject!

what is missing now is to do!
I speak for BTL of course ;-)

Touafé Jonule ... the worst part is that the methods are perfect: https://www.econologie.com/liquefaction- ... -2989.html

[jonule]

there marked "the hydrogen sector" at the top?
weird ...

I'm talking about the Fischer Tropsch process to transform BIOgas by fueling Diesel!
it is otherwise more interesting! -)

[Christophe]

It is marked hydrogen fuel because it takes H2 to liquefy the biomass, that's all.

The FT process is mentioned in the doc ... moreover if I am not mistaken at the origin it was, like makhonine, to liquefy coal ...
