Burning of Sulfur-Containing Liquid Fuels in Fluidized Catalyst Bed

Abstract

Results are presented of the process of burning of sulfur-containing liquid fuels in a nonisothermal fluidized bed of a ShchKZ-1 industrial catalyst for the example of sulfurous and heavy high-sulfur oil. The optimal (“dropdown”) temperature profile in the bed was determined. This profile is characterized by a downstream decrease in temperature from 700 to 500°C. A mathematical simulation based on the description of experimental data on the variation of the sulfur concentration at the exit from the adsorbent (calcite) bed at its varied charge was used to calculate the specific capacity of the sorbent to be (14.2-15.9) x 10³ g cm³. It was shown that the potential capacity of calcite in fluidized bed exceeds by an order magnitude that in a fixed bed.
