Biofuel production through catalytic pyrolysis

Abstract

A method to transform spent coffee grounds (SCG) waste into bio-oil using microwave-assisted pyrolysis approach includes mixing of SCG, silicon carbide granules, and a catalyst to create a homogeneous mixture. The mass ratio of coffee grounds to catalyst ranges from 10:1 to 20:1. The method further includes microwave irradiation of formed mixture to facilitate the formation of the desired product, wherein the product comprises a first vapor, a second vapor, and a char, and condensing the first vapor to form the biofuel.
