The conversion of syngas to liquid fuels in a dual-bed single reactor process

Abstract

The effects of HZSM-5 temperature and weight hourly space velocity (WHSV) on conversion of syngas to liquid fuels were investigated in a single reactor process. The temperature of FT catalyst was constant (463 K), whereas the temperature of HZSM-5 varied (523, 573, 623 K). The value of WHSV ranged between 16 and 24 h−1. HZSM-5 addition suppressed the formation of CH4 and remarkably enhanced the formation of iso-C5-C12 paraffins. An increase of HZSM-5 temperature resulted in an enhancement of gaseous hydrocarbons, C18+ paraffins, and olefins. The optimal HZSM-5 temperature and WHSV were identified as 523 K and 16 h−1, respectively.
