It can be observed from Figure 1 that the HHV of the fuels increases with increase in hydrogen to carbon ratio and decreases with increase in oxygen to carbon ratio.
He pointed out that SEC was the first company to adopt this environmental option, which is to co-operate with the cement company, after the approval of the recycling technology by the General Authority for Meteorology and Environmental Protection, especially as carbon ash contains high carbon ratio sometimes up to 85 per cent, while the cement plants need this ash as auxiliary fuel with heavy fuel, which is used in furnaces of cement factories.
The standard requires biochar products to have an organic carbon content of at least 10% and to have a hydrogen-to-organic carbon ratio (which is inter alia an indicator for biochar stability) of less than 0.7.
Carbon ash contains high carbon ratio, sometimes up to 85 percent, while the cement plants need this ash as auxiliary fuel with heavy fuel, which is used in furnaces of cement factories.

Renewable methanol that is produced through the gasification process and using biomass is used as a liquid motor fuel as it has a high hydrogen to carbon ratio due to its high octane rating.
Previously, to obtain the hydrogen to carbon ratio in a rock sample, researchers would have to isolate the organic matter, purify it and then send it off to a laboratory to have the elemental hydrogen and elemental carbon content measured.
The main use of water in synfuels production is in hydrogenation to improve the hydrogen to carbon ratio of the product fuel, cooling, and mining and residuals disposal.
This is due to natural gas' high hydrogen to carbon ratio. (Methane, its main ingredient, has only four carbon atoms for each hydrogen atom.) A simple cycle gas turbine (operating at a nominal 35% efficiency) produces about 1 lb of C[O.sub.2] per hp per hour.
