Effect of nanoparticles on the nucleation and agglomeration rates of hydrate growth using THF–water clathrates

Abstract Four types of nanoparticles, amorphous carbon, iron III oxide, SiO2, and amino-coated SiO2, were tested to determine changes in tetrahydrofuran–water (THF–water) clathrate hydrate nucleation and agglomeration. Rates were experimentally found to determine their viability for preventing natur...
