Mineral sequestration of CO(2) by aqueous carbonation of coal combustion fly-ash.
The increasing CO(2) concentration in the Earth's atmosphere, mainly caused by fossil fuel combustion, has led to concerns about global warming. A technology that could possibly contribute to reducing carbon dioxide emissions is the in-situ mineral sequestration (long term geological storage) or the ex-situ mineral sequestration (controlled industrial reactors) of CO(2). In the present study, w...
متن کاملEnthalpy Calculation for Pressurized Oxy-coal Combustion
Oxy-fuel combustion is recognized one of the most promising available technologies that zero emission accomplishment may be in the offing. With coal burned under the pressure of 6MPa and oxygenenriched conditions, the high temperature and high pressure gaseous combustion product is composed of 95% CO2 and water-vapor, with the rest of O2, N2 and so on. However, once lauded as classic approach o...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Collisional dissociation cross sections for O + O 2 , CO andN 2 , O 2 + O 2 , N + N 2 , andN 2 + N 2
Using laboratory data for the scattering of O by O2, CO and N2 pair potentials are constructed for O, C and N atoms. These potentials are then used to calculate collisional dissociation and energy transfer cross sections for O on O2, CO and N2; O2 on O2, N on N2, and N2 on N2. Since the energetic ions often neutralize in the atmosphere corona, such cross sections are relevant to plasma ion bomb...
متن کاملinvestigation of the electronic properties of carbon and iii-v nanotubes
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
