Sentence examples for precipitated iron from inspiring English sources

After examining them, Wise concluded that they were "not fossil material at all" but "inorganically precipitated iron siderite nodules".

Three precipitated iron catalysts were evaluated in a stirred tank slurry reactor to determine their performance during Fischer-Tropsch synthesis under steady-state conditions.

This observation prompted a closer examination of the production of alcohols during Fischer-Tropsch synthesis with precipitated iron catalysts containing either silica or alumina and various levels of the potassium promoter.

The voltammetric behaviour of the precipitated iron hydroxide layer is interpreted in terms of the complex structure involving an inner poorly hydrated layer and an outer porous layer recently proposed from in situ ellipsometry data.

The first-order kinetic model could simulate the outflow concentration of dissolved iron during the OMP (R2 = 0.91, 0.69, and 0.68 for CA, CL, and AL, respectively), while the outflow dissolved iron during the CMP was difficult to model because the changed pH and Eh conditions in the mesocosm wetlands cause the former precipitated iron to be mobile after several days.

CEMS shows that the transition from superparamagnetism to ferromagnetism in the precipitated iron nano-clusters critically depends on the implantation dose and post-annealing and that with increasing dose over 2.0×1017 ions/cm2 a ferromagnetic component appears in the Fe implanted MgO samples.

The type of the precipitating agent used during the preparation of a precipitated iron-based Fischer Tropsch (FT) catalyst affects the catalyst pore structure, crystallite size, phase composition and catalytic behavior.

Attrition properties of several oxide supports and precipitated iron-based F T catalyst (100Fe/3Cu/4K/16SiO2 in parts by weight) were evaluated using ultrasound irradiation test and stirred tank slurry reactor (STSR) test under non-reactive conditions.

Low-temperature (230°C), slurry phase Fischer-Tropsch synthesis (FTS) was conducted with precipitated iron-silicon catalysts under industrially relevant conditions (flow=3.1 Nl h−1 g-Fe−1, H2 CO=0.7, P=1.31 MPa).

Magnetic pH sensitive particles were produced by precipitating iron oxide inside hollow organically modified silica particles, and subsequently swelling the shell with a hydrophobic pH sensitive dye.

Injection of HCl acid in these rocks is likely to precipitate iron scales when iron-rich minerals are present (Coulter and Jennings 1997).
