Abstract :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 H 3 PO 4  at different temperatures insert ignore into journalissuearticles values(100, 200, 300 and 400 oC); and at different times insert ignore into journalissuearticles values(30, 45, 60 and 90 minutes);. Parameters such as NaBH4 amount, catalyst amount and temperature of the synthesized MA- H 3 PO 4  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 H 2 min -1 g cat -1 . The reusability of the MA-H 3 PO 4  catalyst was tested 5 times and its stability determined.
