Coal Gasification for Electric Power Generation

Abstract

The electric utility industry is being severely affected by rapidly escalating gas and oil prices, restrictive environmental and licensing regulations, and an extremely tight money market. Integrated coal gasification combined cycle (IGCC) power plants have the potential to be economically competitive with present commercial coal-fired power plants while satisfying stringent emission control requirements. The current status of gasification technology is discussed and the critical importance of the 100-megawatt Cool Water IGCC demonstration program is emphasized.

Characterization of Bulk Structure in Zinc Orthotitanate: A Density Functional Theory and EXAFS Investigation

“… The values presented are compared between DFT calculations for structures taken from Table 2 to EXAFS measurements, in the units of Å. The AAD values were calculated using the Equation 1 …”

“…D evelopment of new sorbent materials that are capable of removing multiple contaminants is critical to meeting the gas clean‐up requirements of high‐efficiency energy conversion processes such as the integrated gasification combined cycle (IGCC) 1–4 . Current technologies in the IGCC typically use a multistage process for contaminant removal.…”

Effects of Feed Composition and Feed Impurities in the Catalytic Conversion of Syngas to Higher Alcohols over Alkali-Promoted Cobalt–Molybdenum Sulfide

“…Coal gasification typically results in a syngas with 10 3 À10 4 ppmv NH 3 and a few hundred parts per million by volume HCN. 28,40 Wood gasification generally results in lower nitrogen levels in the syngas-often 100À1000 ppmv NH 3 and 10À100 ppmv HCN.…”

DFT characterization of adsorption and diffusion mechanisms of H, As, S, and Se on the zinc orthotitanate(010) surface

“…Examples of promising technologies include coal gasification technologies such as integrated gasification combined cycle (IGCC) and integrated gasification fuel cell (IGFC) [1]. The potentially clean fuel that these processes generate will in general be contaminated with trace metals and other species such as CO 2 , H 2 S, HCl, NH 3 , HgCl x , AsH 3 , and H 2 Se.…”
