“…The specific surface area was approximately 7e40 m 2 /g (with the corresponding pore diameter in the range of 14e40 Å ), which is in agreement with the general trend of the perovskite structure synthesized through the solegel method [20,21]. Table 1 the surface of these two perovskite oxides.…”

“…The opposite was observed when the CO 2 content of the gas was increased as has been reported in previous studies [26]. This is not surprising since it is well known that CO 2 can act as an oxidizing agent in this type of reactions, donating oxygen and thus forming CO [30,31]. Both the synthesis gas energy efficiency and methane conversion was increased in case 7.…”

(2013) Modeling of soot formation during partial oxidation of producer gas. Fuel AbstractSoot formation in a reverse flow partial oxidation reactor for reforming of gasifier producer gas has been studied. The process was modeled using a detailed reaction mechanism to describe the kinetics of soot formation. The numerical model was validated against experimental data from the literature and showed good agreement with reported data. Nine cases with differing composition was simulated in order to study the effect of water content, hydrogen content and methane content of the gas. The CO and CO 2 content was also varied to study its effect on soot formation as well as the tar content of the gas. The results show that steam and hydrogen content of the inlet gas had lower influence on the soot formation than expected. The methane content greatly influenced the soot formation. Results also showed that increasing the CO 2 content of the gas reduces the amount of soot formed and gives a higher energy efficiency and methane conversion. For the case with no tars in the ingoing gas the soot formation was significantly reduced. It can be concluded that removing the tars in an energy efficient way, prior to the partial oxidation reactor, will greatly reduce the amount of soot formed. Further investigation of tar reduction is needed and experimental research of this process is undergoing.

“…Controlling the carbon formation has been attempted by increasing the basicity by adding an alkali or alkaline earth metal to the catalyst and by controlling the size of Ni particles [8][9][10][11][12][13][14]. In the case of a catalyst whose basicity has been increased by adding an alkali or alkaline earth metal, the adsorption capacity for CO 2 can be increased by modifying the electron density of the surface, eventually leading to an increase in CO disproportionation and decrease carbon http://dx.doi.org/10.1016/j.cej.2015.06.027 1385-8947/Ó 2015 Elsevier B.V.

“…In the case of Ni size modification, the carbon deposition rate on smaller Ni particles is lower. In order to control the Ni size, various methods have been reported, including the use of structural characteristics and increasing the degree of bimetallic dispersion [8][9][10][11].…”
