The current environmental and industrial contexts require constant revision improvement of hydrotreating processes for obtaining cleaner (bio)fuels through the development supported transition metal sulfide (TMS) catalysts. present work proposes a surface-science approach to describe surface-dependent genesis cobalt-promoted active phase (CoMoS) on α-Al2O3 single crystals used as surrogates γ-A...

The super-Brownian motion X % in a super-Brownian medium % constructed in DF96a] is known to be persistent (no loss of expected mass in the longtime behaviour) in dimensions one ((DF96a]) and three ((DF96b]). Here we ll the gap in showing that persistence holds also in the critical dimension two. The key to this result is that in any dimension (d 3); given the catalyst, the variance of the proc...

New mixed H4[SiMonWn-12O40] (n = 6 and 9) Keggin type heteropolyacids (HPAs) have been successfully synthesized, as confirmed by single-crystal XRD, Raman IR spectroscopy analysis. The resulting polyoxometallates were used for preparation of hydrotreatment catalysts. Mo(W)/Al2O3 catalysts synthesized incipient wetness impregnation alumina support with water solutions prepared HPAs corresponding...

The present work deals with fitting literature data of ASTM Distillation curves and obtain a new correlation suitable to use in modeling when optimizing the refining processes, such as distillation, FCC, catalytic reforming, hydrotreating, etc.
 results showed that values predicted by are very good agreement range mean overall deviation (%MOD) is (0.305-0.585).

This paper argues that innovation can be best understood as an information process which is then concretized as a product that meets demand. Two very different firms, Canon Inc. and Apple Computer Inc., are used as case study illustrations. Innovation does not proceed through logical deduction, but rather is furthered by the use of metaphors and analogies. The bureaucratic and staid structures ...
