摘要

研制了一种新型吸油剂——还原氧化石墨烯（rGO）和聚四氟乙烯（PTFE）超疏水气凝胶。分别制备了2:1、1:1和3:2组合物的氧化石墨烯/聚四氟乙烯气凝胶，其接触角均大于160°。还原氧化石墨烯/聚四氟乙烯（2:3）颗粒和相同组成的块体对原油的吸附量最高，分别为26和58.5 g/g。提出了一种利用载油气凝胶的方法，通过蒸馏低沸点馏分和压制气凝胶来获得沥青混凝土混合料的疏水添加剂。

Superhydrophobic Graphene Aerogel as a New Oil Sorbent

New oil sorbents, superhydrophobic aerogels of reduced graphene oxide (rGO) and polytetrafluoroethylene (PTFE), were developed. The rGO/PTFE aerogels of 2 : 3, 1 : 1, and 3 : 2 compositions were prepared as granules and blocks with contact angles larger than 160°. The rGO/PTFE (2 : 3) granules and the block of the same composition exhibit the highest sorption capacity for crude oil: 26 and 58.5 g/g, respectively. A procedure was suggested for utilization of the oil-loaded aerogels by distillation of low-boiling fractions and pressing of the aerogel to obtain a hydrophobic additive to asphalt concrete mixtures.

期刊介绍： Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas. Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
