“…The most widely used model is known as the Component Model presented in different papers [7][8][9]. Blanco et al [10] characterize tar from the pyrolysis and gasification of refuse derived fuels, and has also been used to characterize the possible decomposition reactions of both primary and secondary tars [11,12].…”

HIGHLIGHTS-Posidonia oceanica thermal decomposition is studied. -Combustion, pyrolysis and gasification at different experimental conditions are performed.-The combined effect of the presence of oxygen, air, water vapor and dolomite in the decomposition bed is analysed. -Conditions where maximum ratio H 2 /CO is observed are optimized. ABSTRACTIn the present work, a very detailed study of the reforming of syngas produced in the decomposition of Posidonia oceanica is done. The effect of the presence of different amounts of dolomite is analysed. Also pyrolysis is studied, in nitrogen atmosphere, and gasification in the presence of air, oxygen and different amounts of steam. A detailed discussion on formation and destruction of tars is done. Furthermore, the effect of the heating rate in the decomposition and the residence time of the evolved gases are discussed. Syngas with ratio H 2 /CO from 0.3 to ca. 3 can be obtained from this interesting material. Marine species (microalgae) are usually studied with the aim of cultivate them for gas or oil production, but in this paper we draw attention to the possibility of using a natural resource with a very small impact in the ecosystem.

Table 2: Operating conditions, properties of the gas and solid phases used in the simulation were extracted of the following references (Silva, 2012;Zhao et al, 2010;Yao et al 2007 The Figure 4 shows the net rates of each chemical species relative to the time variable at the output of the LF. The net rates r H2 , r CO, r CO2 reported an increase between 0.00 sec.…”

ABSTRACT-The study presents a mathematical model to analyze the dynamic evolution of molar concentrations of toluene (C 7 H 8 ) , water vapor (H 2 O) carbon monoxide (CO), hydrogen (H 2 ) , methane (CH 4 ) and carbon dioxide (CO 2 ) in a catalytic reactor of fixed bed. The mathematical model was discretized using the method of lines (MDLs) to transform the system of partial differential equations (PDEs) in a system of ordinary differential equations (ODEs). The system of ODEs has been solved by the implementation of the method of Runge-Kutta Gill to estimate the chemical species C 7 H 8, H 2, CO, H 2, CH 4 and CO 2 .The estimation allows the quantification of individual forecasts of the variables presented in this study. However, valuable information can be obtained from the estimated behaviors in catalytic fixed bed reactor. The model has allowed the validation of chemical species (H 2, CO and CO 2 ) by comparing the optimized values. Additionally, the concentrations for chemical species C 7 H 8, H 2, CO, H 2, CH 4 and CO 2 was studied.

“…To assess the efficiency of a classical reforming process, model molecules such as benzene [139][140][141], toluene [142,143] are usually studied and can provide insight for the VOCs utilization and processing. The existing studies are more oriented on steam reforming reaction using conventional catalysts such as Rh based catalyst [144][145][146][147], supported Ni catalyst [148][149][150][151][152][153][154], Ni-mixed oxide: perovskite [155-159] and hexaaluminate [148].…”

Abstract:The treatment of volatile organic compounds (VOC) emissions is a necessity of today. The catalytic treatment has already proven to be environmentally and economically sound technology for the total oxidation of the VOCs. However, in certain cases, it may also become economical to utilize these emissions in some profitable way. Currently, the most common way to utilize the VOC emissions is their use in energy production. However, interesting possibilities are arising from the usage of VOCs in hydrogen and syngas production. Production of chemicals from VOC emissions is still mainly at the research stage. However, few commercial examples exist. This review will summarize the commercially existing VOC utilization possibilities, present the utilization applications that are in the research stage and introduce some novel ideas related to the catalytic utilization possibilities of the VOC emissions. In general, there exist a vast number of possibilities for VOC OPEN ACCESSCatalysts 2015, 5 1093 utilization via different catalytic processes, which creates also a good research potential for the future.
