Amino acids assisted hydrothermal synthesis of W-type SrFe18O27 nanostructures; a potential hydrodesulfurization catalyst

摘要: Abstract Upon fuel combustion, sulfur oxides are emitted, causing a very harmful sour. Although industrial catalysts recently used to remove most organosulfurs, but it still remains as major challenge for hydrodesulfurization (HDS) of saturated organosulfur analogs. Here we show the method preparation W-type hexagonal ferrites, SrFe18O27 nanoparticles using various amino acids (Valine, Cysteine and Glutamine) after thermal treatment. However, pure sample with homogeneous texture obtains in Valine, which is well-matched JCPDS 34–1366. Moreover, band formation - two bands at 555 cm−1 603 cm−1 -, elemental analysis, repetitive regular lattice structure support orderly nanoparticles. The uniform crucial achieving highly active efficient catalysts. Utilizing reaction variables such temperature, liquid hourly space velocity (LHSV), catalyst concentration H2/oil ratio determine activity typical process. towards desulfurization, have shown reasonable gasoline moderate conditions (9 MPa, 380 °C, LHSV 2 h−1). Furthermore, kinetic models (Power Low model Langmuir-Hinshelwood) confirm that HDS irreversible an exothermic profile. Owing unique properties, attempt has been developed utilize novel micro-trickle bed reactor. results reveal can foster development low-cost nanocatalysts based on mixed metal promising hydrodesulfurization.
