Abstract

Abstract: Iron nanoparticles in carbon nanogranules have been in‐situ generated during the synthesis of lower olefins from Syngas. Very uniformly distributed these carbon embedded iron nanoparticles are found to be very selective for the direct F−T synthesis of lower olefins. The iron incorporated carbon nanogranules were synthesized from refinery heavy residue/vacuum residue and ferrocene. The iron nanoparticles are sTable and do not undergo major sintering during the activity run. The HRTEM images show well dispersion of iron nanoparticles during reduction to reaction processes. Abstract : Heavy petroleum residue/vacuum residue termed as waste has been utilized in an efficient approach to create wealth by synthesizing Nano‐catalytic materials. The Nano‐catalytic materials acquire very good morphology during exposure to syngas gases in the direct synthesis of lower olefins. The selectivity of olefins is greatly influenced by the particle size of the catalysts.
