The exploitation of the biomass as renewable energy have resulted to be a significant solution for the growing trend of the worldwide energies market. In particular, many attentions have been addressed toward use/valorization of agro-industrial residues and waste in these last years. In Italy, every year the juice industries produce about 1 million tons of citrus peels, involving significant environmental problem related to disposal of solid wastes [1], Hence, the conversion of these by-products would represent a significant source of energy if it could be valorized by gasification technology. In this context, aim of this work was to investigate about the effect of volcanic lava as catalyst on citrus peel residues conversion into hydrogen rich syngas through air-steam gasification. In according to recently authors experiences [2,3] gasification experiments were carried out in a bubbling fluidized bed (BFB) reactor at 993 K, 1 bar and different steam to biomass inlet ratios (0.5

One of the priorities in energy field research programs of European Union (UE) is to identify some strategic technologies that can contribute to the shift towards a low-carbon economy by 2050. This is particularly true for the transport sector that today is marked by an extreme dependency on oil. In this area, hydrogen production technologies and the Fuel Cell (FC) systems will play an extremely important role in the portfolio for the future mobility sector. Distributed production of hydrogen is the most feasible approach for introducing hydrogen as an energy carrier in the near term. This approach requires less capital investment for the smaller capacity of hydrogen initially needed, and it does not require a substantial hydrogen transport and delivery infrastructure. The installation of infrastructure for refueling hydrogen should go hand in hand with the entry not only into the automotive market of fuel cell vehicles but also into the naval transport sector. In this regards, the report, "Global Market for Hydrogen Fuel Cell Vehicles," reports that by 2020, sufficient hydrogen filling infrastructures would be in place in several regions of the world, giving an initial boost to the market for hydrogen fuel cell vehicles. In this policy, it is of strategic value to carried out efforts to have suitable and effective-cost hydrogen production technologies. At moment, among these ones i) reforming of natural gas, biogas or liquid bio-fuels, ii) gasification of biomasses and iii) water electrolysis seem to be promising for near-term, providing that critical aspects of such technologies are solved.

Objective: Several reports suggest psychological factors may play a role in the etiology or course of alopecia areata. However, empirical info

In this paper we outline preliminary results obtained on a MCFC monocell. A description is given of the results obtained from experiments at 893 K, which were carried out without replenishing the electrolyte. In order to identify the structural and morphological changes, extensive analyses were conducted on the anode, cathode matrix, and hardware. The pore volume distribution was determined using a microstructure porosimeter C. E. Model 2000.
