摘　　要：高含硫油气田开发面临剧毒硫化氢的安全处理及所形成的硫资源化利用的双重科学挑战。随着石油天然气生产行业不断发展,其加工过程中副产的硫磺越来越多,硫磺产品除用于制硫酸、化肥和橡胶添加剂等主流用途外,开发新的硫磺相关产品或材料显得尤为重要。为此,聚焦于高含硫油气田开发中硫化氢的处理及硫的有效利用问题,提出了通过硫磺改性金属硅酸盐生产新型建筑材料的创新思路,并进行了硫磺改性金属硅酸盐的实验室研究和分析,提出了相关材料可能的应用领域。研究结果表明:①用氯化锌和氯化铝对无定形二氧化硅进行改性,有助于增加无定形二氧化硅表面活性中心数量;②物理化学和量子化学计算表明,金属氯化物与无定形二氧化硅中的氧和硅发生了化学反应;③在生产硫磺改性金属硅酸盐的工艺中应用金属(Zn、Al)氯化物作为亲电活化剂,所制得的材料指标优良,满足建筑行业要求。结论认为,研究成果不仅解决了含硫废弃物处理难题,还开辟了用硫磺改性金属硅酸盐生产新型建筑材料的新途径,产品具有广阔的应用前景,具有重要的生态意义和经济价值。The development of high-sulfur oil and gas fields faces dual scientific challenges of safe treatment of highly toxic hydrogen sulfide and resource utilization of the formed sulfur.With the continuous development of the oil and gas production industry,more and more sulfur is produced as a byproduct in the process.Sulfur products are mainly used for producing sulfuric acid,fertilizers,and rubber additives,besides,the development of new sulfur-related products or materials is particularly important.Therefore,focusing on the treatment of hydrogen sulfide and the effective utilization of sulfur during the development of high-sulfur oil and gas fields,this paper puts forward an innovative idea of producing advanced building materials by modifying metal silicates with sulfur.In addition,sulfurmodified metal silicates are studied in laboratory,and the potential application fields of the related materials are proposed.The following results are obtained.First,modifying amorphous silica with zinc chloride and aluminum chloride is conducive to increasing the number of active centers on the surface of amorphous silica.Second,the calculation results of physical chemistry and quantum chemistry indicate chemical reaction of metal chlorides with oxygen and silicon of amorphous silica.Third,when metal(Zn and Al)chlorides are used as electrophilic activators in the production of sulfur-modified metal silicates,the materials produced have excellent performance indicators,meeting the requirements of the construction industry.In conclusion,the research results not only solve the difficulties in treating sulfurcontaining wastes,but also open up a new way to produce advanced building materials with sulfur-modified metal silicates.The products have broad application prospects and important ecological significance and economic value.
