Description
Technical Field
The invention belongs to the technical field of comprehensive utilization of biomass energy and carbon dioxide, and particularly relates to a method for synergistically converting straw briquette fuel and carbon dioxide through heat.
Background
The annual crop straw yield of China is quite rich, 8-9 million tons are produced annually, except for being partially used for papermaking and livestock feed, about 3.5 million tons can be used as energy, and the annual crop straw yield is reduced by about 1.8 million tons of standard coal and is a huge resource, but the crop straw has the defects of resource dispersion, low energy density, small volume weight, inconvenient storage and transportation and the like, and the large-scale application of the crop straw is severely restricted. With the increase of income of people, commercial energy (such as coal, liquefied petroleum gas and the like) becomes main cooking energy in rural areas close to commercial energy production areas, so that crop straws utilized in the traditional mode can become replaced objects firstly, are abandoned in fields as organic solid wastes, and part of the organic solid wastes are incinerated randomly, thereby wasting precious renewable resources, seriously polluting the atmosphere and damaging the living environment of human beings. The crop straw forming fuel technology can lead the original dispersed crop straws to be compressed into the formed fuel with fixed shape and larger density without raw materials with certain shape through the processes of drying, crushing, forming and the like, saves the transportation and storage cost, expands the application range, and improves the utilization efficiency (Wangzaiwei, Reyngiu, Yueyanfeng, Yangyua, Lifeng, He in the summit, Hakking, Zhujinling. straw forming fuel system economic analysis, agricultural organization research, 2012, 34(2), 203:206. Wangzaiwei, Liangfeng, Leishu, Lijinyuli, Yangyu, Hakkaihe, biomass forming system integration and automation design renewable energy, 2011, (29) (4) 132), Wanjiawei, Changyu, Chanxia, Lejiu, Lifeng, Cifeng, Zhaofei, Yanhua, display, Wuyi, Hefeng, Haokui and Zhujinling. forming fuel forming mold, china, ZL 2015100746651). And the relevant industrial standard (the technical condition of the biomass solid briquette fuel, NY/T1878-2010) and the local standard (the basic requirement of clean utilization of the straw briquette fuel, DB 34/T3656-2020) are issued and implemented, so that the popularization and the application of the straw briquette fuel are powerfully promoted.
The gasification or pyrolysis of the straw briquette is a process of converting hydrocarbon which forms the straw briquette into combustible gas containing carbon monoxide, hydrogen and the like under certain thermodynamic conditions. The gasification of the straw-shaped fuel is generally carried out by using gases such as nitrogen, argon, helium, air, steam, etc., or a mixture of partial gases thereof, and converting the crop-shaped fuel into combustible gases such as carbon monoxide, hydrogen, methane, etc., by thermochemical reaction under high temperature conditions (Zhang Weijie, Guanhai, Jiang, Sun Feng, Xun, Yan Li, Liu, Hu safety, gasification test of the corn straw-shaped fuel in a composite fixed bed, Shandong science, 2017;30(4): 67-72.). Pyrolysis of straw briquettes generally heats straw briquettes under gas-insulated conditions to convert them into low-molecular combustible gases (Wangzagwei, Hexiaofeng, Zhaobaozhu, Baiwei, Zhujinling, Lotisu. Experimental research on biomass pyrolysis utilization system. agro-computerized research, 2009;31(3): 150-.
The straw formed fuel is different from fossil fuels such as coal and the like, contains more oxygen elements while containing carbon and hydrogen elements, so that the straw formed fuel can be subjected to oxygen-containing bond breakage when being subjected to high temperature heat to generate gas containing carbon dioxide, the oxygen elements are exhausted along with the breakage after pyrolysis lasts for a certain time, and volatile components at the time can be further broken under the conditions of atmosphere gases such as air, oxygen, water vapor and the like (Rongshui, Luzhou. In addition, the addition of the catalyst can promote the further deep cracking reaction of volatile components, hydrocarbon and other gases in the thermal conversion process of the biomass to generate combustible gas with smaller molecular weight, thereby reducing the generation of tar in the thermal conversion process, improving the gasification efficiency of straw forming fuel, improving the heat value of the combustible gas and improving the energy conversion rate (Yuyiming, Mongolian dream, field river epitaxy, ash building, beauty and economic, summer sesame aroma. the catalyst has influence on the gasification property of rice hull steam and the conversion of tar. energy engineering 2021, (4) 8-16+ 24.). The nickel-based catalyst in the catalyst has the advantages of high catalytic activity and low cost, can effectively reduce the generation of tar in the thermal conversion of biomass, but is easy to inactivate by carbon deposit and nickel sintering (Shangshang, Lanqui, Wang Yan, Zhang Juan, Qizhenhua, Lijianfen. research progress of biomass tar reforming catalyst, biomass chemical engineering 2020;54(6): 65-73.).
The efficient and reasonable utilization of carbon dioxide is an important way for reducing greenhouse gases in the atmosphere and achieving the aim of carbon neutralization. During the pyrolysis and gasification processes of the straw formed fuel, the volatile components contain long-chain hydrocarbon gas, so that the tar problem is caused, and the long-chain hydrocarbon gas becomes a main factor for preventing the efficient utilization of the straw formed fuel. But no method for the synergistic thermal conversion of straw briquette fuel and carbon dioxide under the action of a catalyst is disclosed and reported at present.
