Catalyst production for the transformation of crudes into gasoline and other fuel products is a billion dollar/year business and fluid cracking catalysts (FCCs) represent almost half of the refinery catalyst market. During the cracking reactions, the FCC surface is contaminated by metals (Ni, V, Fe, Cu, Na) and by coke deposition. As a result, the catalyst activity and product selectivity is reduced to unacceptable levels thus forcing refiners to replace part of the recirculating equilibrium FCC inventory with fresh FCC to compensate for losses in catalyst performance. About 1,100 tons/day of FCC are used worldwide in over 200 fluid cracking catalyst units (FCCUs). It is for these reasons that refiners' interest in FCC research has remained high through the years almost independantly, of crude oil prices. However, recent oil company mergers and the dissolution of research laboratories, have drastically decreased the number of researchers involved in petroleum refining research projects; as a result the emphasis of research has shifted from new materials to process improvements and this trend is clearly reflected in the type of papers contained in this volume. Modern spectroscopic techniques continue to be essential in the understanding of catalyst performance and several chapters in the book describe the use of 27Al, 29Si and 13C NMR to study variation in FCC acidity during aging and coke deposition. In addition several chapters have been dedicated to the modeling of FCC deactivation, and to the understanding of contact times on FCC performance. Refiners efforts to conform with environmental regulations are reflected in chapters dealing with sulfur removal, metals contaminants and olefin generation.

Latin American Fiction and the Narratives of the Perverse contains analysis of sexual perversion and narrative creativity in fictions from the Latin American boom and post-boom. O'Connor's main argument is that orthodox criticism of Latin American literature has neglected the eccentric singularities of other fictive trends in the corpus (especially in the second half of the twentieth-century). At the same time, by examining these eccentric singularities in their relationship to mainstream trends in the Latin American corpus, O'Connor forces his readers to view these master narratives and major trends (such as modernismo or magical realism) from surprisingly new angles. Five of the authors discussed (Puig, Lezama, Lima, Cortazar and Sarduy) have an established place in the Latin American literary canon. A fifth one, Rosario Ferre, may have come close to achieving that status with her earlier fictions. Others (Felisberto Hernandez, Alicia Borinsky, Cristina Peri Rossi and Silvia Molloy) are less well known, but they are certainly highly significant authors for scholars and students of contemporary Latin American fiction.
