Abstract: Abstract: Lignocellulosic biomass is a clean and renewable energy source due to its abundance, wide distribution, and CO2 neutrality. Biomass gasification can convert straw biomass into three different products, namely bio-gas, bio-char, and tar which can be used in different industry fields. The bio-gas can be burned in a boiler or engine for the supply of heat and electricity. The bio-char can be used as a precursor for the production of briquette fuel for heat supply or the activated carbon used in the purification of sewage. Therefore, the comprehensive utilization of straw biomass through biomass gasification technology is of great importance to achieve the goal of “carbon neutrality” and “emission peak” in China. In this work, maize stover (MS) was gasified in a small-scale fixed-bed gasification reactor. The effect of gasification temperature and equivalent ratio on the properties of gasified gaseous, liquid, and solid products were tested. Results showed that with the increase of the gasification temperature from 700?C to 900?C and equivalent ratio from 0.05 to 0.30, the yield of producer gas gradually increased from 48.49% and 59% to 59% and 74.91%, respectively, while the yield of bio-char gradually decreased from 25.30% and 19.89% to 19.89% and 5.28%, respectively. In addition, the lower heating value (LHV) of the producer gas was improved at higher GT and lower ER. The maximum LHV of producer gas was 11.26 MJ/Nm3 with the component distribution of H2 (22.00%), CO (25.91%), CH4 (13.59%), and CnHm (1.12%) which was obtained at gasification temperature of 900?C and equivalent ratio of 0.05. Furthermore, the contents of C, H, and volatiles remarkably decreased with the increase of gasification temperature and equivalent ratio, while the content of ash remarkably increased. The bio-char gradually transformed into ash at higher gasification temperatures and ER due to the severer combustion reaction between the combustible compound in maize stover and the oxygen in the atmosphere. At last, the component in the gasified liquid product was mainly composed of phenols, alcohols, acids, aldehydes, and aromatics. With the increase in gasification temperature, the contents of phenols, alcohols, acids, and aldehydes in the liquid product decreased from 39.29%, 14.82%, 4.8%, and 9.60% to 5.26%, 3.4%, 0, and 0%, respectively, while that of aromatics and esters increased from 0.32% and 20.45% to 50.5% and 30.2%, respectively. With the increase of the equivalent ratio, the contents of aromatics and phenols in the gasified liquid product decreased, while that of others increased. This work revealed the evolution pattern of basic properties of gasified gaseous, solid, and liquid products at varying gasification temperatures and equivalent ratios which could provide basic data for the design and application of large-scale maize stover gasification.
