How much CO2 produced by burning one barrel of oil

How much CO2 produced by burning one barrel of oil.

 

For the oil
Mineral oil has a density of around 0.8 g/cm3, “good” crude oil of around 0.8 – 0,83 g/cm3 and “heavy” crude oil is above 0,92 g/cm3

Crude oil consists (by weight) of 83% to 87% carbon.

One barrel is about 159 liters. Assuming a density of 0,85g/cm3 for our oil we would end up with 135 kg of oil, which contains on the higher end (87% carbon) 118 kg of carbon.

For the carbon dioxide:
Carbon Standard atomic weight: 12.0107(+/- 0.00008) g·mol−1
Oxygen Standard atomic weight: 15.9994(+/- 0.00003) g·mol−1
Lets say: Carbon = 12 and 2 x Oxygen = 2 x 16 = 32 => Total: 44
(12/44 = 27.27% of Carbon in CO2)

100/27,27 = 3,67 X 118 kg = 432,71 kg CO2

About Egidius Kuhlmann

Reading about peak-oil, overpopulation, “Terra Preta” and biochar in 2009 and after making batches biochar for soil improvement from garden residue, I thought, why not make biochar from corpses. Deeply worried about the unsustainable path 'we' as humanity have taken, I see a future where fossil fuels are scarce, the western economic growth model in tatters, the global temperature rises due to the CO2 concentration in the atmosphere with an growing population reaching billions more humans than is sustainable? Thinking along those paths, the question “how can we dispose so efficiently and with the least amount of energy of human remains” became the starting point.
