Hydrodesulfurization over model sulfide cluster-derived catalysts
(Elsevier, 1991)
There is growing interest in the use of organometallic clusters as precursors to model heterogeneous catalysts. This interest is partially derived from the expectation that "solid-state metal complex catalysts" will be ...
Colloidally induced smectitic fines migration: Existence of microquakes
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1997-03)
The phenomenon of colloidally induced fines migration is a challenge of both scientific and industrial importance. Its occurrence impacts permeability reduction and alteration of flow pathways in porous media, particulate ...
Acid- and base-treated Fe 3+ -TiO 2 -pillared clays for selective catalytic reduction of NO by NH 3
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-03)
Fe 3+ -ion-exchanged delaminated pillared clays (PILCs) have been found previously to be more active than the vanadia-based catalysts for selective catalytic reduction (SCR) of NO by NH 3 . The effects of acid treatment ...
Second-order sonochemical phenomena--extensions of previous work and applications in industrial processing
(Elsevier, 1974)
The first-order properties of acoustic waves (i.e., the to and fro particle displacement and velocity) can produce a number of second-order phenomena: cavitation, acoustic streaming, surface instability and radiation ...
Implicit-adsorbate model for apparent anomalies with organic adsorption on natural adsorbents
(American Chemical Society, 1984-12)
Effects of surface morphologies on flow behavior in karst condjuits
(Proceedings of the 15th Int. Congress of Speleology, 2009)
An interactive process flowsheeting and simulation system based on relational data structures
(Elsevier, 1981-12)
An interactive graphical interface has been developed for a modular-sequential steady-state chemical process simulation program. The interface software, called AGPSS (A Graphical Process Simulation System), consists of ...
The toughening of polyamide-6 by brominated poly(isobutylene-co-p-methylstyrene): fracture and toughening mechanisms
(Elsevier, 1993-11)
A study on the toughening of polyamide-6 (PA-6) with a new elastomeric modifier, brominated poly(isobutylene-co-p-methylstyrene) (BrXP-50), was conducted. Morphological analyses and mechanical tests were combined to evaluate ...
