Substitution of Biomass for Coal and Coke in Ironmaking Process Zhengwen Hu1, a, Jianliang Zhang1, b, Haibin Zuo1, c, Mi Tian2, d, Zhengjian Liu1, e, Tianjun Yang1, f 1School of Metallurgical and Ecological Engineering, University of Science and Technology Beijing, Beijing 100083, China 2 No. 4 Steelmaking Plant of Wuhan Iron and Steel Group Corporation, China ahuzhengwen1986@163.com, bjl.zhang@metall.ustb.edu.cn, czuohaibin@ustb.edu.cn, dtianmi2010@126.com, eliuzhengjian@126.com, fyangtj@ustb.edu.cn, Keywords: Biomass, biochar, ironmaking, replacement for coal and coke, low carbon Abstract: Biomass is renewable and carbon neutral.
Furthermore, metallurgical coke, one of indispensable raw materials for blast furnace, is in increasing shortage and coking process causes serious pollution.
Biomass, referring to all living matters on the earth, is a general term for organic materials derived from plants such as grasses, crops, trees, etc.
It was therefore one of the biomass materials that could directly replace conventional coke for large blast furnaces.

The basic infrastructure contains soil base, pavement elevation, grade of slope, shape, paving and materials, which determine the basic content of sidewalks (refer to theCode for Design on Accessibility of Urban Roads and Buildings.
Similarly, worse design of slope and inappropriate choice of shape and materials will also bring people about some trouble unnecessarily.
Here we assign the part without damage shares the proportion of the total to Gs); Gd——Reasonable pavement degree(It shows the degree of reasonableness and non-defectivenessthat materials and pavements achieved.

These materials present self-lubricating properties that make dry machining the best option.
Other materials such as mild steels can be dry machined with the assistance of air for chip removal.

Development of Planar Technology "Anyone might say without any exaggeration that the issues of structural self-formation is the subject of natural science"[109].
All technological processes in planar technology may be classified as deposition, removal or transformation of material.
I.Prigogine Any real object can be seen as a complex of different materials arranged in a certain manner in Euclidean space.
Manufacture or development of such an object can be perceived as a rearrangement of these materials by either removing or adding new ones.

First of all, the gasoline was cut into the light fractions and the heavy one, the light fractions as the reaction material reacted with alcohol to produce alkyl ether, then mixed with heavy fractions and obtained etherified gasoline[2].
Experimental Experimental Materials.
The following materials were used for the preparation of catalyst: macropore pseudo-boehmite, Hβ, sesbania powder and nitric acid.
