Abstract
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.
