The environmentally friendly clay/carbon composite (SBE/C) was prepared by one‐step
pyrolysis under N2 atmosphere at 700° C of spent bleaching earth (SBE) from the industrial …

This study aimed to clarify the catalytic characteristic and hydrogen supply of spent
bleaching clay (SBC) in the pyrolysis of corncob lignin. The effects of lignin doping ratio (0 …

Today, regulations and consumer awareness demand production technologies with
