Scalability Analysis of CNT Growth in Flame-Chemical Vapor Deposition (FCVD) with Fluidized Bed

In the synthesis of carbon nanotubes (CNT) using flame-assisted chemical vapor deposition (FCVD), increasing the mass of beads and growth time will allows for a greater production of carbon nanotubes (CNT) using flame synthesis. Limited studies have conducted a comprehensive analysis of the scalability of using high surface area substrates in flame chemical vapor deposition (FCVD). Thus, the present study focuses on the growth of Carbon Nanotubes (CNT) on spherical substrates (0.3 mm zirconia beads) in FCVD. The primary target is to investigate the scalability of high surface area substrates on CNT growth in FCVD based on percentage of CNT growth area at varying mass of beads. The research’s significance lies in enhancing the understanding of how high surface area substrates can scale up CNT production and reduce costs by increasing bead mass. The production cost of CNT is significantly influenced by the production process and various factors such as materials, utilities, and labor costs. In this study, we will examine the cost of production for ceramic and zirconia in relation to CNT growth. Three cases will be discussed, which include comparing the production cost between zirconia and ceramic under LSR conditions, analyzing the production cost of zirconia with 5 g and 20 g of beads, and assessing the production cost of zirconia with 20 min and 30 min growth times.
