Synthesis gas production process for natural gas conversion over Ni–La2O3 catalyst

Effect of Preparation Method on the Performance of 10Ni/MgAl2O4 for Dry Reforming of Coke Oven Gas

“…The activity and stability were significant effected by crabon deposit cause the activility center can be blocked by crabon deposit. 3.10Ni/MA-c performed the highest activity, the conversion of CH 4 and CO 2 were 76.3 % and 89.2 %, the selectivity of H 2 and CO were 84.3 % and 90.3 %, which show good application potential in the dry reforming of coke oven gas for syngas production.

“…The most widely used is for methanol synthesis when the H 2 /CO ratio is 2 [4]. Nowadays, the methane reforming is used for the preparation of syngas through partial oxidation, steam reforming or dry reforming [5,6].…”

“…Nowadays, the methane reforming is used for the preparation of syngas through partial oxidation, steam reforming or dry reforming [5,6]. Coke oven gas (COG) is a by-product and surplus gas in the steel industry, which consist of H 2 (57-60 %), CH 4 (23-27 %), CO (5-8 %) and CO 2 (< 3 %), if only just burnt away may be harmful to the environment [7]. Dry reforming, especially COG dry reforming is that two major greenhouse gas converted into two energy gas (CH 4 +CO 2 ↔ 2CO+H 2 ), the H 2 /CO ratio is 2.…”

“…MgAl 2 O 4 with spinel structure is stable and resistance on sintering at high temperature. MgAl 2 O 4 is easily available and can improve dispersion of active metal, reduce the size of the particles and increase of CH 4 and CO 2 adsorption and decomposition, but different preparation methods of support have big influence on the stability and activity of the catalyst and there was few research on it. Koo et al [9] also obtained that 10Ni-5Ca/MgAl 2 O 4 catalyst was better than other Ni/Ca ratio in activity and stability which MgAl 2 O 4 support can provide high structure stability at 900 o C. Naeem et al [10] used the polyol and surfactant-assisted methods to synthesize Ni-based and found that surfactant-assisted catalysts presented high resistance on carbon deposition.…”
