“…Rhenium is also widely used to promote the cobalt catalyst [101,102]. ZrO 2 proved to be a very good promoter for cobalt catalyst, it can improve the CO conversion rate and C5+ selectivity [103][104][105].…”

Fischer-Tropsch synthesis is a set of catalytic processes that can be used to produce fuels and chemicals from synthesis gas (mixture of CO and H 2 ), which can be derived from natural gas, coal, or biomass. Biomass to Liquid via Fischer-Tropsch (BTL-FT) synthesis is gaining increasing interests from academia and industry because of its ability to produce carbon neutral and environmentally friendly clean fuels; such kinds of fuels can help to meet the globally increasing energy demand and to meet the stricter environmental regulations in the future. In the BTL-FT process, biomass, such as woodchips and straw stalk, is firstly converted into biomass-derived syngas (bio-syngas) by gasification. Then, a cleaning process is applied to remove impurities from the bio-syngas to produce clean bio-syngas which meets the Fischer-Tropsch synthesis requirements. Cleaned bio-syngas is then conducted into a Fischer-Tropsch catalytic reactor to produce green gasoline, diesel and other clean biofuels. This review will analyze the three main steps of BTL-FT process, and discuss the issues related to biomass gasification, bio-syngas cleaning methods and conversion of bio-syngas into liquid hydrocarbons via Fischer-Tropsch synthesis. Some features in regard to increasing carbon utilization, enhancing catalyst activity, maximizing selectivity and avoiding catalyst deactivation in bio-syngas conversion process are also discussed.

“…Meanwhile, a lot of oxides, such as zirconia, were used as promoter to synthesize highly active silica-base FTS catalyst [11]. By introducing different sols other than SiO 2 sols into silica pellets, the multi-functional bimodal pore support can be formed, where besides spatial effect of bimodal pore structure, new chemical phenomenon or effect might appear with the hetero-atom formation between different oxides.…”

“…In general, the potential commercial cobalt catalysts are typically composed of four components: Co metal, a small amount of a second metal, oxide promoters (alkali, rare earth, and/or transition metal oxide such as ZrO 2 ) and supports (silica, alumina or titania) [1][2][3][4][5]. Recently, zirconia has drawn much attention for CO hydrogenation.…”

La-modified ZrO 2 with 10 mol% La was prepared by three different methods, namely co-precipitation, impregnation, and mechanical mixing and employed as cobalt catalyst supports. The use of La-modified ZrO 2 prepared by mechanical mixing resulted in higher cobalt dispersion and higher CO hydrogenation activity than those supported on pure oxide (La 2 O 3 and ZrO 2 ) and La-modified ZrO 2 obtained by the other methods. As revealed by XRD and TEM, an intimate contact and/or incorporation of La atoms in ZrO 2 may occur on the La-modified ZrO 2 prepared by co-precipitation and impregnation, which induced a stronger interaction between cobalt and the support. On the other hand, the presence of amorphous La 2 O 3 in ZrO 2 by mechanical mixing facilitated cobalt reducibility as shown by lower reduction temperature in the TPR profile.
