Abstract

An efficient conversion of cellulose to CH4over porous Ni catalyst under hydrothermal conditions has been investigated. The results indicated that porous Ni catalyst showed significant catalytic activity and selectivity for the cellulose conversion to methane. Porous Ni catalyst still remained good activity with gaseous hydrogen after three runs for the transformation. The maximum CH₄ yield of 73.8% from cellulose was achieved in the presence of Zn as a reductant over porous Ni at 325°C for 2 h. This value obtained is the highest yield for the formation of CH4from cellulose to date. The mechanistic studies for this transformation proposed three possible pathways for the formation of CH₄ from cellulose: (1) pyrolysis,(2) hydrogenation of intermediates, and (3) methanation. The present work provides an environmentally benign and efficient route for the conversion of cellulose to CH₄with high efficiency and high selectivity and has great significance for both academia and industry.
