“…The process is claimed to generate no pollution as the produced carbon can be used as manufacturing feedstock in industry or be landfilled. Along a similar direction, the Kværner process 89 has been developed by the Norwegian engineering firm Kværner that produces H 2 from hydrocarbons (e.g., natural gas and biogas) in a plasma burner at 1600 °C (C n H m → n C + m /2H 2 ). Although the production of H 2 from methane pyrolysis and the Kværner process are clean as they do not produce any greenhouse gas, the produced H 2 is nonrenewable due to the use of fossil fuel feedstock.…”

Homogeneous Catalysis for Sustainable Energy: Hydrogen and Methanol Economies, Fuels from Biomass, and Related Topics

As the world pledges to significantly cut carbon emissions, the demand for sustainable and clean energy has now become more important than ever. This includes both production and storage of energy carriers, a majority of which involve catalytic reactions. This article reviews recent developments of homogeneous catalysts in emerging applications of sustainable energy. The most important focus has been on hydrogen storage as several efficient homogeneous catalysts have been reported recently for (de)hydrogenative transformations promising to the hydrogen economy. Another direction that has been extensively covered in this review is that of the methanol economy. Homogeneous catalysts investigated for the production of methanol from CO 2 , CO, and HCOOH have been discussed in detail. Moreover, catalytic processes for the production of conventional fuels (higher alkanes such as diesel, wax) from biomass or lower alkanes have also been discussed. A section has also been dedicated to the production of ethylene glycol from CO and H 2 using homogeneous catalysts. Well-defined transition metal complexes, in particular, pincer complexes, have been discussed in more detail due to their high activity and well-studied mechanisms.

“…The overall reaction between glucose and steam can be expressed as follows:

{normalC}_{6} {normalH}_{12} {normalO}_{6} + r {normalH}_{2} O \to

l CO + m {normalH}_{2} + p {normalH}_{2} O + q {normalCO}_{2} + v {normalCH}_{4} + w C false(R . 1 false)

where

r

represents the steam/glucose molar ratio and

q = (3 + \frac{r - l - p}{2}); v = (3 + \frac{r - m - p}{2}); w = (p - r + \frac{m - l}{2})

“…As reported in Reference 4 a major part of the published investigations on biomass gasification models favor the equilibrium approach, the calculation of it being performed applying either the S or/and NS-methods. [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] The experimental study of glucose gasification using steam is of importance since glucose represents a simple biomass surrogate. 37 Here, we propose to perform thermodynamic computations of the equilibrium composition for this gasification process under various conditions.…”

Chemical equilibrium calculations—as they are required to evaluate the evolution limits of any reactive system—are fundamentally performed using either a reaction based stoichiometric (S) approach or a non‐stoichiometric (NS) method. One objective of the present paper is to check and discuss whether both methods lead to comparable solutions in the case of complex chemical equilibria encountered in high temperature and pressure combustion of hydrazine and propane and in steam gasification of glucose and cellulose. Within both calculation models various numerical methods can be used. We apply several techniques for each approach and discuss their easiness of implementation and usage, in particular when chemical equilibria are computed for reacting systems under a multitude of temperature and pressure conditions and feed compositions. In addition, we present a novel approach to perform sensitivity analyses based on a combination of S or NS methods and arc‐length continuation technique. For this purpose, three industrially relevant case studies are exposed: (1) synthesis of ammonia using the Haber process, (2) steam gasification of a typical biomass surrogate, glucose, and (3) steam gasification of cellulose. For all the above reacting systems, our results are benchmarked against their counterparts obtained either from the ubiquitous process simulator: ASPEN‐Plus® or from data available in the open literature.
