Study of the activity of a novel green catalyst used in the production of hydrogen from methanolysis of sodium borohydride

Biomass is an important energy source because it is easily accessible, contributes to the protection of the environment, and can be easily used in industry. Biomass resources can be classified as plants, vegetable and animal wastes, urban and industrial wastes. Highly active catalysts can be prepared by physical and chemical activation methods. Here, Microcystis aeruginosa was used as a biomass source and a metal-free catalyst was synthesized. The production conditions were determined by burning the microsistis modified with 3M H3PO4 at different temperatures (100, 200, 300 and 400 oC) and at different times (30, 45, 60 and 90 minutes). Parameters such as NaBH4 amount, catalyst amount and temperature of the synthesized MA- H3PO4 catalyst that affect methanolization were investigated. In the kinetic calculations, the reaction order was found as n 0.18, activation energy 19.014 kj / mol and initial rate 4998.7 ml H2min-1gcat-1. The reusability of the MA-H3PO4 catalyst was tested 5 times and its stability determined.
