The effects of boron incorporation on the ZSM-22 particle size, morphology, and acidity were investigated via a microwave-assisted synthesis method (MAHyS). The in situ addition of boron into the TON framework resulted in ZSM-22 zeolite (TON framewor

Biomass, the feedstock for biocrude and ultimately renewable diesel is a low energy density feedstock. The transport of this feedstock over long distance has been proven to be a major burden on the commercialisation of biorefining. Therefore, it has

Red mud samples were used to catalyse in-situ co-pyrolysis of pinewood and low-density polyethylene for the production of high-quality bio-oil. The sodium cation in the crude red-mud was exchanged with barium and calcium cations and further tested to
