Gasification is a thermochemical process which can be used as a low-emission and highly efficient method to produce syngas and chemicals such as biomethanol and dimethyl ether (DME). In this paper, a review of technologies and methods for economic production of chemicals through gasification of biomass and other fuels has been carried out. A variety of techno-economic studies and analysis have been proposed in order to better understand the technical and economic assessments during the biomass gasification. Results showed that the methanol production cost for biomass (wood) is from 195 to 935 €/t, for waste residues is from 200 to 930 €/t, for coal is from 160 to 480 €/t, and for natural gas is from 90 to 290 €/t. It also concluded that fuel (wood) cost has positive linear relationship with ethanol production cost, meaning as the feedstock cost increases from 30 to 50 $/day-ton, the ethanol production cost enhances from 1.66 to 1.95 $/gal.

气化是一种热化学工艺，可以用作生产合成气和化学品（如生物甲醇和二甲醚（DME））的低排放，高效方法。在本文中，对通过气化生物质和其他燃料进行经济生产化学品的技术和方法进行了综述。为了更好地理解生物质气化过程中的技术和经济评估，提出了各种技术经济的研究和分析方法。结果表明，生物质（木材）的甲醇生产成本为195至935€/ t，废渣为200至930€/ t，煤炭为160至480€/ t，天然气为90至290€/ t。还得出结论，燃料（木材）成本与乙醇生产成本成正线性关系，
