“…After removing the sulfur and carbon dioxide contaminants, the syngas is reacted over a catalyst in the FT reactor to produce high-quality clean fuels following the formula (4) (Greyvenstein et al, 2008). Biomass is more reactive than coal and (depending on the technology) is usually gasified at temperatures of between 550 ºC and 1,500 ºC and at pressures varying between 4 and 30 bars (Damartzis & Zabaniotou 2011;Leibold et al, 2008;Steinberg, 2006). Typically, biomass is burned in an electrically heated furnace consisting of several multiple-tube units that can be heated separately up to 1,350 °C (Theis et al, 2006).…”

This review compiled the life cycle (LC) studies on ethanol produced via gasification of biomass centering on greenhouse gas (GHG) emission and production cost to discuss their potential environmental and socioeconomic impacts. Numerous efforts have been made to evaluate the LC of ethanol produced with biosynthesis (gasification-microbial fermentation) and chemical synthesis (gasification-catalytic synthesis) of syngas produced from biomass (hereafter referred to biosyngas), and deals with system boundary, feedstock, energy paths and utilization of by-products to determine the environmental impacts as well as the production cost. It seems that most of the LC studies were conducted based on different research targets. Most of the reviewed studies support the environmental and economic viability of ethanol except for a few examples. A wide variation was observed in the reported GHG emission and production cost of ethanol which are dependent on the system boundary and assumptions, feedstock, conversion technologies and plant sizes. Consequently, in-depth studies are needed for each stage of the LC of ethanol from biosyngas for any future investment, commercial production, and sustainability. Moreover, a careful consideration has to be placed on the land use change and soil quality and their rebound effects if lignocellulosic biomass is to be put to use in the ethanol industry. LCA MethodologyLife cycle assessment (LCA) is a tool for evaluating environmental effects of a product, process, or activity throughout its life cycle Inventory analysisThe inventory analysis involves data collection on raw materials and energy consumption, emissions to air, water and soil, and solid waste generation. The inventory analysis is the most work intensive and time consuming phase in an LCA, mainly because of data collection. The data collection can be less time consuming if good databases are available and customers and suppliers are willing to help. Nowadays, many LCA databases are exists and can normally be bought together with LCA software. Data from databases can be used for processes that are not product specific, such as general data on the production of electricity, coal or packaging. However, site-specific data are required for product specific data. Inputs are energy (renewable and non-renewable), water, raw materials etc. Outputs are the products and co-products, and emission to air, water and soil and solid waste generation.

“…Compared to fossil fuels, biomass-which is a carbon neutral renewable energy, since the CO 2 from its utilization can be captured via photosynthesis-exhibits great prospects for limiting global gas pollution (NO x , SO 2 and greenhouse gases) and the energy crisis [1]. Biomass gasification is considered a promising technology with relatively lower temperatures, low energy consumption and a high ability of CO 2 capture, attracting a lot of attention all over the world [2].…”
