The catalytic effect of both oxygen-bearing functional group and ash in carbonaceous catalyst on CH 4-CO 2 reforming

Weidong ZHANG, Yongfa ZHANG,

Frontiers of Chemical Science and Engineering 2010, Volume 4, Issue 2,   Pages 147-152 doi: 10.1007/s11705-009-0242-1

Abstract: It has been found that the carbonaceous catalyst is an efficient catalyst on CO-CH reforming.The oxygen-bearing functional groups play a significant role in the carbonaceous-catalyzed CO-CH reforming; the ash components in carbonaceous catalyst also have an important influence on the CO-CH reformingFeO, NaCO, and KCO in the ash can catalyze the CO-CH reforming reaction; CaO has little effect on CO-CHCaO can catalyze the gasification between carbonaceous catalyst and CO; AlO and MgO inhibit the CO-CH

Frontiers in Energy 2009, Volume 3, Issue 3,   Pages 341-347 doi: 10.1007/s11708-009-0023-z

Abstract: A dual fuel head poly-generation flowsheet was designed based on coal gas and coke oven gas. To help clearly understand the system performance, a 1.2×10−3.2×10kg methanol and 274―496MW power poly-generation system was simulated by using the commercially available software ASPEN Plus and GT Pro. The technology scheme, the operating parameters, and the efficiency of the system were also analyzed and evaluated, which will be used for building industrial devices.

Review on cryogenic technologies for CO removal from natural gas

Yujing BI, Yonglin JU

Frontiers in Energy 2022, Volume 16, Issue 5,   Pages 793-811 doi: 10.1007/s11708-022-0821-0

Abstract: CO2 in natural gas (NG) is prone to condense directly from gas to solid or solidify from liquidMeanwhile, CO2 will also affect the calorific value of NG.Based on the above reasons, CO2 must be removed during the NG liquefaction process.In this paper, the phase behavior of the CH4-CO2 binary mixture is summarized,which provides a basis for the process design of cryogenic CO2 removal from NG.
