Interactions of n-Alkanes within a Restrictive Pore System under Fluid Catalytic Cracking (FCC) Conditions

Cracking of n-C8 and n-C16 single feedstocks and their mixture was used to test interactions of alkanes, under fluid catalytic cracking (FCC) conditions, within the pores of ferrierite zeolite and MFI-type ZRP-5 zeolites (before and after SiCl4 chemical vapor deposition (SiCl4-CVD) modification). Ov...

Description
Summary:Cracking of n-C8 and n-C16 single feedstocks and their mixture was used to test interactions of alkanes, under fluid catalytic cracking (FCC) conditions, within the pores of ferrierite zeolite and MFI-type ZRP-5 zeolites (before and after SiCl4 chemical vapor deposition (SiCl4-CVD) modification). Over ferrierite zeolite and SiCl4-CVD-modified ZRP-5 zeolite, the cracking of n-C16 in a 50/50 (v/v) mixture of n-C8 and n-C16 is greatly suppressed, because of both the restrictive environment (narrowed pore openings) and the presence of n-C8. Comparison of the cracking gas yield and the selectivity to C3 in LPG over ZRP-5 zeolites before and after SiCl4-CVD modification has also been presented.
