Catalytic reforming reduction

For the refiner, the reduction in benzene concentration to 3% is not a major problem it is achieved by adjusting the initial point of the feed to the catalytic reformers and thereby limiting the amount of benzene precursors such as cyclohexane and Cg paraffins. Further than 3% benzene, the constraints become very severe and can even imply using specific processes alkylation of benzene to substituted aromatics, separation, etc.

In this work, the catalytic reforming of CH4 by CO2 over Ni based catalysts was investigated to develop a high performance anode catalyst for application in an internal reforming SOFC system. The prepared catalysts were characterized by N2 physisorption, X-ray diffraction (XRD) and temperature programmed reduction (TPR).

Measures to reduce lead are likely to have a two stage effect. In the short term, reduction from present levels to 0.15g/l with no change in octane quality will be compensated by increased use of catalytic reformate and higher aromatics contents (up to 10 more). Assuming that there is a valid relationship between total aromatics content (and fuel PNA content) and PNA emissions there is the potential for some increase in PNA emissions in the short and medium term.

Catalytic reforming of methane with carbon dioxide, also known as dry reforming, has recently attracted considerable attention due to the simultaneous utilization and reduction of two types of greenhouse gases, CO2 and CH4, for the production of synthesis gas. The reactions of CO2 reforming and oxy-C02 reforming are as follows ... 

Several studies were performed in order to establish the mechaiusm (5-7). The currently accepted mechartism, presented in Scheme 26.1 for the Pd(BINAP) catalyzed amination, involves the formation of a complex, Pd(BINAP)2 from a catalyst precursor (usually Pd(OAc)2 or Pd2(dba)3) and ligand this complex lies outside the catalytic cycle and undertakes dissociation of one BINAP to form Pd(BINAP) the following steps are the oxidative addition of the aryl halide to the Pd(BINAP), reaction with amine and base, and the reductive elimination of the product to reform Pd(BlNAP).
