. Calcium oxide (CaO) has been acknowledged as a catalyst to produce hydrogen-rich gas and has currently gained broad attention … due to its cheapness and abundance. Nevertheless, the deactivation of CaO after carbonation reaction is challenging for … continuous hydrogen production and economical perspective. To conquer such challenge, the concept of CaO-based chemical looping …

research interest in a novel near zero emission energy utilization system which is based on CaO sorption enhanced gasification …. This paper presents the experimental results of pressurized CaO sorption enhanced sawdust gasification in a self …-design pressurized fluidized bed gasifier, aiming to survey the effects of reaction pressure, CaO to carbon mole ratio (CaO/C), steam to …

To figure out the role of CaO (calcium oxide) on WGS (water gas shift) reaction and the related enhancing mechanism …, the WGS reaction of absorption enhanced biomass steam gasification with CaO addition was performed with thermodynamic … temperature and far from equilibrium without CaO addition. However, much higher H2 concentration could be obtained with CaO …

catalytic biomass gasification using a modified CaO-based catalyst. The catalyst was prepared by adding 5% Ni as a primary …

The behavior of liquefaction of Shengli (SL) lignite with methanol and CaO in the presence of FeS and tetralin (THN …) was studied. The effects of reaction temperature and time on the liquefaction behavior of SL lignite with methanol and CaO …. The results show that SL lignite liquefaction with methanol and CaO in the presence of FeS is one of the feasible …

. IGCC with CCS is regarded as a promising option to mitigate CO2 emission. In this paper, the CaO sorption-enhanced process … conventional IGCC–CCS to produce a hydrogen-rich stream, which is sent onto a gas turbine. CaO is used as the sorbent to enhance … hydrogen production and for CO2 capture. Regeneration of CaO is completed via calcination in a regenerator vessel. The IGCC …
