Synthesis, characterization, and performance of x_MoO3/Z‐22 and x_MoO3/MMP catalysts for biodiesel production

The Canadian Journal of Chemical Engineering, EarlyView.
Methyl transesterification of soybean oil using heterogeneous catalysts for biodiesel production. Abstract The growing global demand for renewable fuels has driven the search for efficient catalysts in biodiesel production. This study presents the synthesis and characterization of x_MoO3/Z‐22 and x_MoO3/MMP heterogeneous catalysts, and evaluates the ...

Tunable amylopectin graft copolymers for flocculating and dewatering iron ore tailings

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Polyacrylamide (PAM), the standard flocculant for mining tailings, often produces turbid supernatants and poorly dewatered sediments, limiting water reuse and tailings densification. We synthesized amylopectin‐graft‐poly[(2‐methacryloyloxy)ethyl]trimethylammonium chloride (AP‐g‐PMETAC) copolymers with systematically varied graft frequency (N =
