1. A method for removing sulfur from a liquid fuel comprising one or more organosulfur compounds, comprising:
contacting the liquid fuel with a hydrodesulfurization catalyst in a reactor in the presence of hydrogen gas, thereby forming a fuel mixture comprising less sulfur than the liquid fuel,
wherein the contacting is carried out at a temperature in a range of from 250 to 350° C. for up to 6 hours and a hydrogen gas partial pressure in a range of from 50 to 60 bar-a,
wherein the hydrodesulfurization catalyst comprises:
catalytic material comprising molybdenum and cobalt; and
a catalyst support comprising alumina;
wherein the catalyst support further comprises carbon nanofibers dispersed on a surface of the alumina; and
wherein the hydrodesulfurization catalyst further comprises a dopant comprising boron, and
wherein the hydrodesulfurization catalytic material is homogenously dispersed on the catalyst support.
