En el presente trabajo se expone parte del resultado obtenido a raíz del encargo que la Excelentísima Diputación de Alicante realizó a INECA (Instituto Estudios Económicos Provincia de Alicante), por medio del cual se analiza de forma integral la implantación de una zona franca en la provincia de Alicante. Este elemento, tomando a la Autoridad Port...

Non-oxidative methane aromatization is an attractive direct route for producing higher hydrocarbons, highly selective to benzene despite the low conversions due to thermodynamic limitations, and Mo/H-ZSM-5, the first catalyst proposed for this reaction, is still considered as one of the most adequate. The major problem of this process is the severe...

A new aluminosilicate zeolite (ITQ-39) has been synthesized. This is an extensively faulted structure with very small domains that makes the structure elucidation very difficult. However, a combination of adsorption spectroscopy and reactivity studies with selected probe molecules suggests that the pore structure of ITQ-39 is related to that of Bet...

Should entrepreneurship education be the same in every country or should it be adapted to each context? In addition to answering this question, it appears to be important to identify the concerns students have regarding their entrepreneurship education programs, so as to strengthen their perceptions of feasibility and desirability of an entrepreneu...

TNU-9 is a medium pore zeolite with a complex tridimensional channel system. Its catalytic properties have been studied in some reactions that involve the BTX fraction, such as benzene and toluene alkylation with methanol, ethanol or isopropanol. These reactions use in practice medium pore zeolites such as ZSM-5 (MFI) or MCM-22 (MWW), and the selec...

MCM-36 is a catalytically active material made by swelling and subsequent pillaring of a layered zeolite precursor, MCM-22(P). However, the swelling procedures lead to significant destruction of layer structure and alteration of framework silicon/aluminum (Si/Al) ratio, which are likely to influence the acidity and catalytic activity of the final m...

The catalytic behaviour of two multipore zeolites containing channels of different sizes, SSZ-33 (10 windows × 12 MR) and ITQ-22 (8 × 10 × 12 MR pores), for alkylation of benzene with ethanol and benzene with isopropanol or propylene, has been studied and compared to that of zeolites with intersecting channels of the same size, ZSM-5 (10 × 10 MR ch...

Purpose – In order to extend the literature on predicting entrepreneurial intentions this study aims to test a model incorporating cultural, social, and psychological factors. Design/methodology/approach – The paper surveyed over 1,000 students at universities in the USA, Spain, and China. Findings – Across cultures, university students share gener...

The unique pore topology of zeolite ITQ-13 with 9-membered ring (MR) channels intersected by perpendicular 10-MR channels and larger void space with 10-MR cross-sections was studied for meta-xylene isomerization and disproportionation. Product distribution was interpreted on the basis of pore topology and compared with zeolites with 12-MR (β), 10-M...

The unique pore topology of zeolite NU-87, with 10-membered ring (MR) channels intersected by perpendicular 12-MR cavities, can offer new opportunities for alkylaromatics isomerization, as well as for aromatics alkylation. The catalytic performance has been studied for meta-xylene isomerization and disproportionation, as well as toluene alkylation...

We could characterize today's business world with numerous attributes, namely: dynamism, turbulence, complexity, etc. But if we had to give a brief definition of the specific challenges business management will have to face in the next century, the best choice would surely be talking about ‘global market’ and ‘knowledge management’. These are the t...

Universidad de Valencia, Burjassot, Valencia (Spain) *cmsanche@itq.upv.es Introduction Zeolites are microporous materials characterized by their crystalline structure containing channels and cavities of molecular dimensions. One of the most interesting properties of zeolites derived from their microporous structure is their shape selectivity when u...

This paper shows a descriptive study about human resources in certified firms (1S0 9000), using quality manager perceptions. The study analyzes the methods that can be used to involve staff those personnel policies which have suffered any change and the effects of ISO 9000 on human resources. The results show, on the one hand, that training is a po...

La presente obra comienza por análizar el papel que la pequeña empresa desempeña en la economía y perfilar las características que la definen. Analiza luego las cualidades y virtudes que debe poseer quien pretende crear una empresa de este tipo. Finalmente, se hace un estudio empírico sobre las pequeñas empresas en Europa, con énfasis particular en...
