Abstract

This study focuses on the fabrication of nickel nanoparticles (Ni NPs) using a chemical reduction method with hydrazine monohydrate as the reducing agent. The Ni NPs were characterized using transmission electron microscopy (TEM) and X-ray di raction spectrometry (XRD). The characterization results confirmed the production of pure Ni NPs with an average particle size ranging from 50 to 90nm and various shapes depending on the hydrazine ratio. The synthesized Ni NPs were then utilized to enhance the viscosity reduction of heavy oil. Significant viscosity reduction of 51%, from 7128 mPa.s to 3495 mPa.s, was achieved at a temperature of 80 °C. Additionally, a slight decrease in density from 0.9514 g/cm3 to 0.9416 g/cm3 and a slight increase in the (American pertroleum institute) API number from 17.04 to 18.59 (9.0%) were observed.
