A novel integrated, thermally coupled fluidized bed configuration for catalytic naphtha reforming to enhance aromatic and hydrogen productions in refineries

Catalytic Combustion for Supplying Energy for Endothermic Reaction

“…Recuperative coupling has been proposed in the literature both as a potential configuration to reduce the size and increase the productivity of existing conventional industrial reactors, and as a design strategy to develop small and very small scale systems aiming to work as portable devices to produce energy. It has been reported that the performance of some large scale reactors having a tube and shell heat exchanger [3][4][5][6][7][8][9][10][11] (Figure 1) or a concentric tubular configuration may be significantly increased by turning them into a recuperative configuration [12][13][14][15][16][17]. Here, the endothermic reaction generally occurs in the tube side and the exothermic reaction in the shell side, which, additionally, may include a multi-pass configuration for heat recovering and fuel pre-heating [15].…”

Optimal design of a thermally coupled fluidised bed heat exchanger reactor for hydrogen production and octane improvement in the catalytic naphtha reformers

“…In continuation of the previous work (Rahimpour et al, 2011b), the underlying objective of this study is to use DE approach in order to find the most appropriate (optimum) operating conditions and enhance the productivity and efficiency of the mentioned configuration. Following the best configuration with the optimal geometric and operating variables, improves the reactor performance.…”

“…Hence, some improvements would be suggested in both the processing and equipment pieces of this process. The opportunity to address all the above issues, including higher aromatic and hydrogen production in addition to reducing the disasters by coking, seems to be achievable in the proposed configuration for catalytic naphtha reactor (Rahimpour et al, 2011b) called thermally coupled fluidised bed heat exchanger reactor. Subsequently, optimisation approach can be used to identify the best design of TCFBNR and enhances the reactor performance.…”

Toward enhanced hydrogen production in a catalytic naphtha reforming process

“…These authors studied the applications of multi spherical fixedbed reactors [32,34], membrane radial fixed-bed reactors [35,42] and fluidized bed reactors [38] within a CNR process, with the intention to boost aromatic and hydrogen production. Moreover, several articles studied the effects of coupling exothermic processes with CNR process, so as to optimize process performance [36,40].…”
