TL;DR: In this paper, it was shown that platinum catalyzes the reduction of TiO 2 to Ti 4 O 7 and deposits as thin pill-box structures on the surface of the Ti O 7.

TL;DR: In this paper, a plot of intergranular volume vs. depth was constructed using data from relatively uncemented reservoir sandstones from a variety of depths, ages, and geographic locations.
Abstract: To evaluate compaction as a factor in porosity evolution, a plot of intergranular volume vs. depth was constructed using data from relatively uncemented reservoir sandstones from a variety of depths, ages, and geographic locations. The resulting intergranular-volume-decline curve reveals that sands compact mechanically and intergranular volume declines rapidly, from about 40 to 42% at the surface, to about 28% at 1500 m. Between about 1500 and 2500 m, intergranular volume continues to decline slowly, until the framework stabilizes at around 26% (maximum potential porosity in the absence of cement or matrix). No further significant decrease in intergranular volume is observed to the depth limits of the data set at 6700 m. Comparison of intergranular volume and volume of quartz cement for different formations reveals no obvious balance between intergranular pressure solution (as monitored by intergranular volume) and quartz cementation. This indicates that grain-to-grain pressure solution and quartz cement precipitation do not proceed concomitantly on the thin-section scale. Moreover, grain compaction is limited (to about 26% intergranular volume) in rigid-grain sandstones, which suggests that the occurrence and distribution of deep porosity is a function of the volume of cement available to fill the intergranular pores. Therefore, deep, porous sandstones are relatively uncemented rather than undercompacted.

TL;DR: In this paper, a systematic experimental study of the promoting effect of the first row transition metals on the hydrodesulfurization (HDS) activity of MoS2 and a systematic theoretical study of simple clusters which model these catalyst systems have been carried out.

15 Oct 1998TL;DR: In this paper, a liquid hydrocarbon composition, containing paraffinic hydrocarbon components in which the extent of branching, as measured by the percentage of methyl hydrogens (BI), and the proximity of branching was defined, was investigated.
Abstract: A liquid hydrocarbon composition, containing paraffinic hydrocarbon components in which the extent of branching, as measured by the percentage of methyl hydrogens (BI), and the proximity of branching, as measured by the percentage of recurring methylene carbons which are four or more carbons removed from an end group or branch (CH2⊃4), are such that: (a) BI - 0.5(CH2⊃4)⊃15; and (b) BI + 0.85(CH2⊃4)∫45 as measured over said liquid hydrocarbon composition as a whole.

TL;DR: The shape-selective catalysis in molecular sieves has been extensively studied in the literature as discussed by the authors, and the fundamental concepts underlying shape selectivity have been used very effectively in the development of new catalysts for the petroleum and petrochemical industries.
