Abstract:
... This work reports a kinetic study of C₃H₆ catalytic partial oxidation (CPO) over Rh/α-Al₂O₃. CPO and steam reforming experiments were carried out in an isothermal annular reactor and quantitatively analyzed by a mathematical model following both a molecular and a microkinetic description of the surface reactivity. The results showed that, in line with that of other hydrocarbons such as CH₄ or C₃H₈ ...

Abstract:
... Oxidative steam reforming (OSR) of methane is investigated under exhaust gas reforming conditions in a wall-coated catalytic microchannel reactor. The process is run over different combinations of Pt- and Rh-based catalysts, namely 0.2% (by weight) Pt/Al₂O₃–2%Rh/Al₂O₃, 2%Pt/Al₂O₃–2%Rh/Al₂O₃, and 2%Rh/Al₂O₃–2%Rh/Al₂O₃. In each combination, coated catalysts are locked on the opposite walls of a rect ...

3. Modular Gas-to-Liquid: Converting a Liability into Economic Value

Author:
Koortzen, Johannes G.; Bains, Sabjinder; Kocher, Lary L.; Baxter, Iain K.; Morgan, Ross A.

Subject:
Fischer-Tropsch reaction; air; catalysts; economic valuation; engineering; fuels; methane; oil fields; risk; synthesis gas; taxes
Abstract:
... The disposal of associated gas can be a significant impediment to remote oilfield development. Although several associated gas management options exist, most either are too costly or cannot be moved to the oilfield. The production of syngas can be achieved by a variety of techniques, but again some of these require a dedicated air separation unit, which adds complexity and safety risks to the faci ...

Subject:
catalysts; engineering; free radicals; gases; mass transfer; methane; models; oxidation; pellets; porosity; texture; thermodynamics
Abstract:
... A microkinetic model for oxidative coupling of methane (OCM) has been developed that comprises a reaction network of 39 gas-phase and 26 catalytic elementary steps. It has been implemented in a heterogeneous reactor model that explicitly accounts for the interactions between gas phase and surface species. Concentration gradients arising from mass transport limitations are found to develop inside t ...

Abstract:
... This study examines the role that silica nanoparticles play on the permeation of methane, ethane, and propane gases through two types of polyurethane (PU) membranes: one based on polyether and the other based on polyester. These PU membranes are synthesized from polycaprolactone (PCL225) polyester and polypropylene glycol (PPG) polyether in a 1–3–2 mol ratio of polyol/hexamethylenediisocyanate/1,4 ...

Abstract:
... A mixture of 20% CO₂, 50% CO, 25% H₂, and 5% CH₄, which reflects the gas composition from coal gasification, was subjected to vacuum pressure swing adsorption (VPSA) in order to remove CO₂ from the gas fuel. Zeolites and activated carbons were used as adsorbents. The performance of the VPSA process was assessed through the CO₂ recovery and productivity and the product purity. A strong correlation ...
