    Abstract

    An innovative technology to integrate the utilization of biochar and algae in the form of slurry fuel for power generation was conceptualized. This study aimed to understand the rheological properties and stability characteristics of biochar–algae–water (BAW) slurry fuels. The BAW slurries were prepared by mixing pine sawdust biochar and Chlorella vulgaris in different proportions first and then dispersing the mixtures in deionized water. The BAW slurries showed shear-thinning flow behavior, which became more apparent as the algae proportion in the solid increased. The slurries displayed better stability at higher algae proportion due to increased water uptake capacity and enhanced flocculation.
