Fossil Fuels: Types

Coal
oil
Natural Gas

Natural Gas - 56.3 Megajoules per Kilogram
Crude Oil - 46.3 Megajoules per Kilogram
Coal - 24 Megajoules per Kilogram

Type:

• Alcohol Fuel,
  • Methanol
  • Ethanol
  • Biodiesel

Transerification process

$CO2+3H_2\to C{H}_{3}OH+H_{2}O$

Methanol Production
Natural gas → feed preparation → desulphurised natural gas → steam reforming ( inputs CO_2 Air/o2 steam) → synthesis Gas → Methanol synthesis → crude methanol → methanol distilation

Stage 1: Feed preparation

• Natural gas

Methanol Synthesis

$$CO+2H_2\to C{H}_{3}OH$$ $$CO+H_{2}O\to C{O}_2+H_2$$

$C{O}_2+3H_2\to C{H}_{3}OH+H_{2}O$
