The oxidative reforming of methane to synthesis gas on a commercial steam reforming catalyst
The oxidative reforming of methane to predominantly carbon monoxide and hydrogen was studied over a commercial steam reforming catalyst. The said reaction was performed in an integral fixed-bed reactor at temperatures between 575°C and 650°C at a total pressure of 200 kPa(a). The primary objective …

The autothermal reforming of artificial gasoline
… The production of hydrogen by the autothermal reforming of artificial gasoline has been studied. Part of gasoline is oxidised to produce heat and steam to promote the steam reforming of unburnt gasoline to produce hydrogen. The use of platinum impregnated on ceria supports (active for …

The reforming of the electricity supply industry
This study enquires into the choices to be made when selecting and implementing a reform model for the electricity industry. It argues that the appropriate reform model depends on the circumstances in the considered jurisdiction. Especially in small and less developed electricity systems a dilemma …

Reforming institutional responses to violence against women
Battering has been described as an example of the total institution (Avni, 1991), within which batterers use violence, threats of violence, isolation, and other tactics of abuse to enforce compliance with their rules. Battering has well-documented physical, psychological, social, and economic …

Reforming WTO rules on state-owned enterprises
The purpose of this research is to make proposals to the World Trade Organization (i.e., the WTO) rules to address the problem of granting advantages to state-owned enterprises (SOEs). SOEs tend to receive various advantages, including financial advantages, monopolies and exclusive, regulatory …

Exposing the seams : the impetus for reforming U.S. counterintelligence
U.S. counterintelligence is in need of reform. The September 11, 2001 attacks by Al-Qa'ida against America highlight this fact but are not in themselves the reason counterintelligence should be reformed. Not surprisingly these attacks have stirred a general debate on how U.S. intelligence ought to …

Islamic Legal Positivism : Reforming Islamic Jurisprudence Using the Equity
Authoritative legal sources from which laws are derived are the decisive factors that determine the prosperity or failure of a nation. The ancient legal sources can be properly categorized as those sources most likely contribute to misery. In contrast, modern legal sources like public interest, …

Catalytic Tar Reforming Using Biochar During Solid Waste Gasification
… the most promising solution to tars is catalytic reforming. Alas, the catalysts are easily deactivated during the process. On the other hand, chars, which are a byproduct from gasification, have demonstrated their catalytic capabilities for tar reforming and are inexpensive. Although a variety of …

Nanocomposite catalysts for soot combustion and propane steam reforming
… Re and V has been synthesized for propane steam reforming. Nickel aluminate nanocrystals with various Ni/Al molar ratios were prepared by chemical co-precipitation. They were pretreated in H2 prior to propane steam reforming to obtain highly dispersed Ni species. The Al in nickel aluminate acted …
