EFFECT OF SPINEL STRUCTURE OF NI BASED CATALYST ON ITS CATALYTIC ACTIVITY AND STABILITY IN CO2 REFORMING WITH CH4

摘要

Due to environmentally friendly and utilization of the greenhouse gas, CO2 reforming of CH4 is attractive process, and produce low H2/CO ratio syngas which is preferable for the Fischer- Tropsch synthesis of long-chain hydrocarbons (1.2). Besides, this reaction can be used in chemical energy transmission system (3.4).Ni based catalysts were widely investigated in the CO2 reforming of CH4 due to high activity and low cost (5-8). However, the major technical problem of methane reforming is very obvious that carbon deposition during the reforming easily results in the catalyst deactivation or reactor blocking by application of Ni-based catalysts (9).
