The book provides the most up-to-date information on testing and development of hydroprocessing catalysts with the aim to improve performance of the conventional and modified catalysts as well as to develop novel catalytic formulations. Besides diverse chemical composition, special attention is devoted to pore size and pore volume distribution of the catalysts. Properties of the catalysts are discussed in terms of their suitability for upgrading heavy feeds. For this purpose atmospheric residue was chosen as the base for defining other heavy feeds which comprise vacuum gas oil, deasphalted oil and vacuum residues in addition to topped heavy crude and bitumen. Attention is paid to deactivation with the aim to extent catalyst life during the operation. Into consideration is taken the loss of activity due to fouling, metal deposition, coke formed as the result of chemical reaction and poisoning by nitrogen bases. Mathematical models were reviewed focussing on those which can simulate performance of the commercial operations. Configurations of hydroprocessing reactors were compared in terms of their capability to upgrade various heavy feeds providing that a suitable catalyst was selected. Strategies for regeneration, utilization and disposal of spent hydroprocesing catalysts were evaluated. Potential of the non-conventional hydroprocessing involving soluble/dispersed catalysts and biocatalysts in comparison with conventional methods were assessed to identify issues which prevent commercial utilization of the former. A separate chapter is devoted to catalytic dewaxing because the structure of dewaxing catalysts is rather different than that of hydroprocessing catalysts, i.e., the objective of catalytic dewaxing is different than that of the conventional hydroprocessing, The relevant information in the scientific literature is complemented with the Patent literature covering the development of catalysts and novel reactor configurations.
Separate chapter was added to distinguish upgrading capabilities of the residues catalytic cracking processes from those employing hydroprocessing. Upper limits on the content of carbon residue and metals in the feeds which can still be upgraded by the former processes differ markedly from those in the feeds which can be upgraded by hydroprocessing. It is necessary that the costs of modifications of catalytic cracking processes to accommodate heavier feeds are compared with that of hydroprocessing methods.
Objective of the short chapter on upgrading by carbon rejecting processes was to identify limits of contaminants in heavy feeds beyond which catalytic upgrading via hydroprocessing becomes uneconomical because of the costs of catalyst inventory and that of reactors and equipment.

This book describes an original improvement in power quality of photovoltaic generation systems obtained by the use of a multilevel inverter implemented with level doubling network (LDN). Modulation principles and harmonic analysis of output voltages are proposed and introduced in detail for both single and three-phase LDN configurations. The analysis is then extended to dc-link current and voltage, with emphasis to low-frequency harmonics and switching frequency ripple. This work represents the first comprehensive implementation of maximum power point tracking (MPPT) schemes using the ripple correlation control (RCC) algorithm in the presence of multiple ripple harmonics, such as in the case of multi level inverters. Numerical simulations and experimental tests are carefully reported here, together with practical insights into the design of dc-link capacitors.

Personal computers would be unwieldy and inefficient without power electronic dc supplies. Portable communication devices and computers would also be impractical. High-performance lighting systems, motor controls, and a wide range of industrial controls depend on power electronics. In the near future we can expect strong growth in automotive applications, dc power supplies for communication systems, portable applications, and high-end converters. We are approaching a time when all electrical energy will be processed and controlled through power electronics somewhere in the path from generation to end use.
