TL;DR: A combination of quaternary phosphonium biocide (preferably TTPC), alcohol, and functional excipients for the oil and gas recovery industry is discussed in this paper.
Abstract: A combination biocide (Glutaraldehyde or OPA), quaternary phosphonium biocide (preferably TTPC), alcohol (preferably isopropyl alcohol), and functional excipients for the oil and gas recovery industry. The functional excipients for the oil and gas recovery industry are a cellulose type proppant, a poloxamer wetting agent, a friction-reducing pluronic block copolymer, a drag reducing agent such as polyethylene oxide, and a flocculating agent. The OPA may be of the dialdehyde C 6 H 4 (CHO) 2 form, and the Glutaraldehyde of formula C 5 H 8 O 2 . Both will produce an inherent bacteriostatic effect and lower surface tension and thus aids in the spread of the TTPC on the biofilm covered surface where it is readily absorbed by the negative surfaces of proteins and bacteria. It thus serves as a binding agent between the TTPC and the application surface. The foregoing constituents are combined in preferred concentrations within acceptable ranges to provide a synergistic biological chemical complementarity system.

TL;DR: In this article, the catalytic performance of the NiO-NiO nanocomposite catalysts was evaluated using adsorption-desorption of acetic acid, and the results indicated that NiO to CuO greatly enhanced the electrical conductivity via the creation of new charge carriers.
Abstract: CuO–NiO nanocomposite catalysts were synthesized by an oxalate precipitation route. The basicity of the catalysts was measured using adsorption–desorption of acetic acid. The catalytic conversion of isopropanol to acetone was carried out in a conventional fixed bed flow type reactor at 200 °C using N2 as a carrier gas. The results indicated that, the addition of NiO to CuO greatly enhanced the electrical conductivity via the creation of new charge carriers (Cu+–Ni3+). In addition, the results revealed that the catalyst containing 30 wt.% NiO calcined at 400 °C possesses the highest catalytic activity with 98% conversion and 100% selectivity to acetone. The remarkable catalytic performance of the synthesized catalysts is attributed to the decrease of the energy gap, the increase in the concentration of charge carries (Cu+–Ni3+), and to the creation of more weak and intermediate basic sites.
