The renewable “green gasoline and diesel” from biomass are of special interest. The Fischer–Tropsch Synthesis (FTS) is an attractive alternative for the production of ultra-clean,sustainable and renewable free-sulfur liquid fuels from syngas conversion. FTS is of great industrial importance due to the great variety of hydrocarbon products obtained, whose abundance depends on the catalysts employed, as well as on operating conditions. Recently, mesoporous materials such as MCM-41, SBA-15 and HMS, have attracted widespread attention as novel supports for the synthesis of Fischer–Tropsch catalysts. For example, Yin and coworkers44 studied the FTS over Co-based catalysts supported on HMS and MCM-41. The Co/HMS catalysts showed higher catalytic performance and selectivity toward C5+ products than the Co/MCM-41catalyst. The superior performance of Co/HMS sample was ascribed to their smaller domain size with shorter channels and larger textural mesoporosity. Lira and coworkers compared Co/HMS and Co/SiO2 catalysts in the FTS. Both catalysts showed selectivity toward C5+ products, specifically towards the diesel fraction (C11-C19).
