This work investigates the production of fatty acid methyl esters (FAME) from Jatropha curcas oil using a variety of heterogeneous catalysts: resins, zeolites, clays, hydrotalcites, aluminas and niobium oxide. For this purpose, a catalyst screening was first conducted in a batch reactor at the...

The paper reviews the pyrolysis of biomass constituents and possible secondary reactions. Biomass pyrolysis yields mostly liquid and solid fuel, easy to store and transport.

In this study, nucleation and grain growth was studied by using 2-dimensional generalized Monte Carlo simulations and experiments. As an attempt to improve the JMAK model, we proposed a new differential equation to be able to model nucleation and growth phenomena using nonextensive...

We seek to provide a general strategy to permit the study of non-equilibrium aspects of conformational transitions in various types of heteropolymers. The theoretical methods we have developed rely mainly on the Gaussian self-consistent approach that replaces the exact non-linear Langevin...

The process of multicomponent condensation is considered. The global evolution of a metastable state originally created in the system has been investigated. Kinetic description of the ordinary one channel nucleation has been corrected. The theory taking into account several channels of...

In this paper, explicit method of constructing approximations (the triangle entropy method) is developed for nonequilibrium problems. This method enables one to treat any complicated nonlinear functionals that fit best the physics of a problem (such as, for example, rates of processes) as new...
