【2026 Pyrolysis Temperature】The impact of the temperature at the outlet of the pyrolysis furnace on the pyrolysis reaction

2026-07-07View Original

Thread Content

What is the effect of the outlet temperature of the pyrolyzer on the pyrolysis reaction? For a fully developed pyrolyzer, its outlet temperature reflects the degree of pyrolysis; therefore, the outlet temperature of the pyrolyzer can influence the distribution of the pyrolysis products as well as the coking behavior within the furnace. Generally, the yields of ethylene and propylene increase as the furnace outlet temperature rises; after reaching a maximum value, an increase in temperature leads to a decline in yields. The yield of butadiene does not change significantly with the furnace exit temperature, while the yields of methane, hydrogen, and heavy fuel oil generally increase as the temperature rises.
