These are 2 major plans (very, too much, ambitious) of biofuel development launched by the French government in the early 80s following the 2 oil crises.
Here is an excerpt from this book that I am reading.
Unfortunately, he only mentions biofuels "politically" (should I say: petroleum? Take a new neologism) correct, ie: ethanol, ETBE and EMVH (diester). However, we will appreciate the many times the authors (4 women academics) mention the diversification of the energy supply and above all energy conservation.
If the subject of official biofuels interests you, it's a bible: http://www.eyrolles.com/Sciences/Livre/ ... angent.php
I learned there, for example, that there was more bioethanol produced in 1913 than in the 1950s and that its production for energy or process destination (manufacture of explosives) never stopped between 1910 and the years 1960 when oil floods the market abundantly and inexpensively.
For example in the 50s Antar had developed the TRI SUPER AZUR 75% petrol, 15% ethanol and 10% benzol abandoned for economic reasons in the 60s.
But back to CARBUROL, here is the extract from the book:
Announced on January 14, 1981 by the government, it aims to find products of national origin substitutable for Hydrocarbons. This program is ambitious and has nothing to do with the statements that the French political and administrative authorities had prepared for many months. The aim is to produce 50% of the fuels used by transport in national territory in 1990. (!!!) The Minister of Industry at the time did not hesitate to speak of 2 million ha devoted to energy production out of the 32 million ha cultivable.
