Intercellular to atmospheric
carbon ratio (Ci/Ca) was also calculated.
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.
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.
