Low-carbon conversion of crude oil to C₂-C₄ olefins by micro Py-GC/MS and a small-scale fluidized-bed reactor

Abstract Green utilization of crude oil has become an important way for energy transformation in the petrochemical industry. Crude to aimed low-carbon (C 2 -C 4 ) olefins had been conducted by micro pyrolysis-gas chromatograph/mass spectrometer (Py-GC/MS) and a small-scale fluidized-bed reactor. Fe-modified Al O 3 /USY catalysts were used catalytic pyrolysis oil. The results showed that product distribution altered hugely after Fe incorporation. Suitable incorporation can promote conversion oil, while excessive could reduce yield light olefins. Bifunctional 1%Fe/USY catalyst good dehydrogenation activity olefin production, which guide clean
