The world is moving toward the goal of achieving net-zero carbon emissions by 2050, and hydrogen energy considered an excellent alternative to nonrenewable sources. In this regard, developing a catalyst that both economically valuable exhibits efficient production primary task at current stage. This study utilized hydrothermal synthesis method prepare nanosized 3-dimensional (3D) hollow sphere CuCrO2-CeO2 for use in Steam Reforming Methanol (SRM) process. characteristics morphology prepared were characterized using various techniques such as XRD, FESEM, HRTEM, FTIR, Raman, etc. spheres with 1:2 ratio exhibited highest efficiency 550 °C, yielding 6372.73 mL STP min-1 g cat-1 per gram catalyst. Furthermore, incorporation CeO2 not only enhanced rate CuCrO2 but also extended applicability nanoparticles wider temperature range. unique 3D structure offers numerous advantages low cost, multiple catalytic reaction sites, easy preparation. Therefore, hold potential commercial development.

Abstract A novel interesting method based on bi‐reforming of methane was proposed for improvement flame thermal characteristics and radiation heat flux (RHF) in natural gas (NG) furnaces. In the plan, done by recirculation flue gas. The recirculated which dominantly including CO 2 H O inert N mixed with a certain part NG flow mixture passed through an array nickel catalysts placed inside helical tube mounted furnace wall to process is done. Gasses temperature 800°C, p = 1 atm ratio CH 4 /(CO + O) 0.8 were condition. results indicated that condition, significant portion converted CO. conversion 98.47% 81.18% while yield as target reaction products 94.40% 93.38%, respectively. Bi‐reforming changed from blue yellow luminous. Furthermore, since adiabatic at greater than hydrogen, generated combusted combustion zone raises temperature. Both enhance luminosity RHF much 30%. Finally, although slightly increases NO x emission, it decreases total amount emission environment, makes environmentally friendly.
