Pd/C and CoPd/C heterogeneous catalysts have been synthesized by adopting Charge Enhanced Dry Impregnation (CEDI). The particles size distribution, their high metal surface-to-bulk ratios, and synthesis feasibility are unmatchable to any known noble metal bimetallic heterogeneous catalyst preparation techniques. Next generation Fuel Cells and Fischer-Tropsch catalytic processes economy will be ...

This contribution is based on the monograph entitled “Recent Advances in Thermochemical Conversion of Biomass”, covering both general items as well as the primary processes, like fast pyrolysis, gasification, hydrothermal liquefaction, carbonization and secondary processes, like co-processing of bio-oil in fluidized catalytic cracking (FCC), Fischer-Tropsch synthesis and valorization of lignin ...

A numerical method for solving second order, transient, parabolic partial differential equation is presented. The spatial discretization is based on Hermite collocation method (HCM). It is a combination of orthogonal collocation method and piecewise cubic Hermite interpolating polynomials. The solution is obtained in terms of cubic Hermite interpolating basis. Numerical results have been plotte...

This paper studies one example of dynamic optimisation of systems subject to hydraulic transportation delays. Properly taking into account the variability of the delay in optimisation is a challenging problem, of importance in several applications. While stationary conditions have been derived in earlier works, here we investigate practical numerical aspects and propose a direct resolution meth...

Abstract. Explicit computational formulas for the coefficients of the periodic normal forms for all codim 1 bifurcations of limit cycles in generic autonomous ODEs are derived. They include second-order coefficients for the fold (limit point) bifurcation, as well as third-order coefficients for the flip (period-doubling) and Neimark-Sacker (torus) bifurcations. The formulas are independent of t...

We present in situ experiments to study the possible formation of cobalt carbides during Fischer–Tropsch synthesis (FTS) a Co/TiO2 catalyst at relevant conditions pressure and temperature. Th...
