Enhanced hydrogen-rich gas production from steam gasification of coal in a pressurized fluidized bed with CaO as a CO2 sorbent

On reliability and flexibility of sustainable energy application route for vehicles in China

“…On energy supply and energy dependence, H 2 is a secondary energy whose production is relied on the consumption of primary energy and the cost of materials. H 2 can be produced from various feedstock via diverse approaches, such as partial oxidation of heavy oils [84], catalytic steam reforming of LNG [85] and oilderived naphtha [86], biological [87], electrolysis of water [88], gasification of coal [89], photochemical catalytic [90], solarthermal chemical [91], etc. However, in the current global, commercial H 2 are mainly from NG (48%), petroleum (30%), coal (18%), and water (4%) [92].…”

Study on bromine release from bituminous coal during combustion

“…During coal combustion, SiO 2 [20][21][22] and CaO [22][23][24][25] are often added in coal as additives to reduce the harmful components release. Vassilev et al [4] stated the volatile Br can be adsorbed on the glass phase, and the Ca, Mg silicate generated in the process of combustion can fixed the Br from authigenic mineral in coal.…”

Promoted calcium looping H 2 production via catalytic reforming of polycyclic aromatic hydrocarbon using a synthesized CO 2 absorbent prepared by impregnation

“…CLG has attracted wide attention in the literature 7‐24 . The main reactions involved are shown in Table 1 5,6 .…”
