The production of ultra-light weight coke proppants for fracturing coal bed methane deposits is presented. The raw material is blast-furnace coke, foundry coke and a coke breeze. The method used obtains coke proppants that meet all the requirements of the ISO 13503-2:2006/Amd.1:2009 standard for proppants used in hydraulic fracturing, with the exception of crush resistance. They have porosity up to 40 % and they are mainly macroporous materials, containing predominantly cylindrical, less frequently bottle-shaped or wedge-shaped pores. The proppants with the lowest crush rate were obtained from the blast furnace coke (CSR > 65 %).

用于煤层气技术的焦炭基支撑剂


介绍了用于压裂煤层气矿床的超轻焦炭支撑剂的生产。原料是高炉焦、铸造焦和微风焦。所用方法得到的焦炭支撑剂满足 ISO 13503-2：2006/Amd.1：2009 标准对水力压裂所用支撑剂的所有要求，但抗压性除外。它们的孔隙率高达 40%，主要是大孔材料，主要包含圆柱形孔，较少见的是瓶形或楔形孔。破碎率最低的支撑剂来自高炉焦炭（CSR > 65 %）。
