The substantial growth in shale-derived natural gas production the US has caused significant changes chemical and petrochemical markets. Ethylene of ethane naphtha via steam cracking is one most energy- emission-intensive activities manufacturing. High operating temperatures, high reaction endothermicity, complex separation create energy demands as well considerable CO2 emissions. In this study...

In this study, a novel solid dendrimer amine (hyperbranched polymers) was prepared using mesoporous carbon nitride functionalized by melamine based dendrimer amines. This adsorbent was denoted MDA-MCN-1. The process was stepwise synthesis and hard-templating method using mesoporous silica SBA-15 as a template. Cyanuric chloride and N,N-diisopropylethylamine (DIPEA, Merck) were used for function...

Hydrogen demand in refineries is increasing vigorously due to the stringent transportation fuel specifications, furthermore the interest in the so-called hydrogen economy developed in the recent years put the hydrogen as energy carrier in the centre of a growing interest. More than 95% of the hydrogen for refinery use is nowadays produced via hydrocarbon steam reforming, where Foster Wheeler pl...

Internal dry reforming (IDR) of methane for biogas-fed solid oxide fuel cell (SOFC) applications has been experimentally investigated on planar Ni-GDC (cermet anode) electrolyte-supported cells. This study focuses the effect CO2 concentration, current density, operating temperature, and residence time internal reforming. A single is fed with different CH4/CO2 mixture ratios between 0.6 1.5. Ext...

The combined dry-steam reforming (CDSR) of a model biogas (66 % CH4 + 34 CO2) has been investigated under various feed compositions and reaction temperature conditions over Ni-Rh/MgAl2O4 catalyst, with the objective to convert excess methane (compared by steam (SR). Methane, however, appeared react preferentially H2O rather than CO2, leading an inhibition dry (DR) in presence steam. CO2 adsorpt...

This chapter reviews recent studies of catalytic reforming of logistic fuels at hightemperature. Aside from steam and autothermal reforming, special consideration is given to partial oxidation conditions. Natural gas, gasoline, diesel, and ethanol containing fuels are discussed. Methane and iso-octane as fuel surrogates are exemplarily used to explain the behavior of the reformers in particular...

copper trimesate (cu-btc) mof has been pointed out as a promising adsorbent for separating carbon dioxide from methane. however, mof’s need to be shaped prior to their use in packed bed adsorbers in order to reduce pressure drop; on the other hand, the production of mechanically resistant shaped bodies reduces their adsorption performance. in this work, cu-btc tablets provided by basf are evalu...
