“…With the conventional silica support used, it is reported that CO2 oxidizes the catalyst and the activity for CO2 hydrogenation is low. Similar results are reported by Jun et al [2004]. Schulz et al [1999] have concluded through their studies that FT with H2/CO and H2/CO2 gave the same product composition at steady state, but the transient episodes existed for a longer time with the CO2-rich syngas.…”

“…The literature dealing with actual conversion of bio-syngas to fuels using FTS is meagre. Jun et al [2004] report experimental results of FTS done using a model bio-syngas. In his review on biofuels, Demirbas [2007] considers FT using bio-syngas as an emerging alternative.…”

“…On the other hand, for a CO2-rich syngas, sufficient H2 is necessary to first enable the reverse-WGS reaction to form CO, which then takes part in the FT polymerisation reactions. This is the mechanism for CO2 hydrogenation perceived by many authors including and [Jun et al, 2004]. The important reactions for FTS using CO-or CO2-rich syngas are as follows:…”

While Fischer-Tropsch synthesis (FTS) using coal and natural gas in conventional reactors is an almost well-established technology, the production of liquid hydrocarbons from syngas obtained from biomass is in its preliminary stages of commercialization in countries like Germany. With concerns about global warming and ways of disposing of CO2 being searched for, CO2 hydrogenation using FTS to liquid hydrocarbons can act as a CO2 sink. A brief review of FTS using CO2-rich syngas is given in this paper, looking at FTS as a technology that can help reduce global warming and as a process integration alternative. The reverse water gas shift (r-WGS) reaction is vital for CO2 hydrogenation. We have studied the effect of this using an FT kinetic model and have proposed a new flow sheet alternative for FTS using CO2-rich syngas. Simulations suggested that this new process gives better conversion of CO2. The product selectivity and yields from an FT plant are vital to make the process viable economically.

“…Unlike the syngas from the gasification of coal (rich in hydrogen), that produced from raw biomass is rich in carbon oxides. Therefore, to suit the conditions of traditional methanol synthesis, it must undergo a series of processes to improve the H 2 /CO 2 proportion, usually the water gas reaction, reforming of methane, or CO 2 elimination (Jun et al, 2004). To date, there is little information regarding how the potential accumulation of trace elements into the biomass of plants grown in contaminated lands could affect the efficiency of gasification processes.…”

The plantation of fast growing trees in contaminated sites, in combination with the use of organic wastes, could partially solve a dual environmental problem: the disposal of these wastes and the improvement of soil quality in these degraded soils. This study evaluated the effects of two composts amendments on the quantity and quality of Paulownia fortunei biomass and on syngas production by biomass gasification, produced by plants growing on trace elements contaminated soils. Compost increased biomass production to values similar to those produced in non-contaminated soils, due to the improvement in plant nutritional status. Moreover, biomass quality for gasification was increased by compost addition. Trace element accumulation in the biomass was relatively low and not related to biomass production or the gas quality obtained through gasification. Thus, P. fortunei plantations could pose an opportunity to Preprint submitted to Elsevier 2 improve the economic balance of the revegetation of contaminated soils, given that other commercial uses such as food or fodder crop production is not recommended in these soils.

“…In a gas composition where the volume percent of CO, CO2, Ar and H2 is 11, 32, 5, and 52 %, respectively, comparable to bio-derived synthesis gas 52 , it is also found that Fe/Cu/Al/K catalysts have significantly higher activity than the silica containing catalysts 53 . The difference in activity under such conditions seems to arise from a higher resistance towards oxidation and higher stability of the carbide phases with alumina as structural promoter 38,53 . One significant difference between alumina and silica supports is the ability of K containing alumina to chemisorb CO2 38,54 .…”
