AI Technical Summary
Existing technologies lack efficient bimetallic catalysts supported on niobium phosphate for catalytic deoxygenation processes of complex oxygenated lignocellulosic and fatty materials, leading to low reactivity and undesirable side reactions such as oligomerization, which hinder the production of high-quality biofuels.
Development of bimetallic catalysts with a general formula AB/NbOPO4, where A is Ni, Co, Ru, or Pd and B is Ag or Cu, supported on niobium phosphate, which undergoes specific reaction conditions to efficiently deoxygenate various oxygenated feedstocks, including cashew nut shell liquid and bio-oils, into high-value hydrocarbons.
The bimetallic catalysts achieve >99% conversion of complex matrices into combustible hydrocarbons, with selectivities up to 100% for green diesel and 87% for pentadecylcyclohexane, and yields of 94-100% for different raw materials, producing high-quality biofuels with reduced impurities and improved stability.
