Abstract:

This thesis describes a study of catalysed steam methane reforming. A microreactor of 3 mm bore, operated and controlled by computer has been used. The catalyst employed was an industrial type steam reforming nickel oxide-alumina catalyst containing 15% nickel. The experiments were performed at temperatures of industrial interest in the range of 600-840°C. The pressure range was 2.5-9 bar, at hydrogen to methane ratios of 0.5-2 and steam to methane ratios of 2-3.1. The catalyst was initially activated at 700°C in a flow of steam and hydrogen (7:1) for 16 hours. Initially, the activity of the c

Abstract:

In this work, a fundamental kinetic model for the catalytic reforming process has been developed. The complex network of elementary steps and molecular reactions occurring in catalytic reforming has been generated through a computer algorithm characterizing the various species by vectors and Boolean relation matrices. The algorithm is based on the fundamental chemistry occurring on both acid and metal sites of the catalyst. Rates are expressed for each of the elementary steps involved in the transformation of the intermediates. The Hougen-Watson approach is used to express the rates of the mol

Abstract:

In this project, the active and stable catalysts were successfully developed for methane reforming reactions under microwave heating. The monometallic Co, Cu, and Mo catalysts supported on either AhO3 or TiO2 were inactive under all tested conditions whilst their respective bimetallic CoMo and CuMo catalysts were highly active and stable at low microwave powers to produce desirable syngas ratios. The activation mechanism of metallicbased catalysts for reforming reactions under microwave heating was explored.

Abstract:

Stringent legislation on control of vehicle exhaust emissions has led to consideration of alternative means of reducing emissions, with hydrogen fuel cell powered vehicles being accepted as one favoured possibility. However, the difficulties of storing and distributing hydrogen as a fuel are such that the conversion of more readily available fuels to hydrogen on board the vehicle may be required. The production of hydrogen by the partial oxidation of isooctane over Rh/Al2O3, Rh/CeO2-?l2O3 and Rh/CeO2-ZrO2 catalysts has been investigated. Oxidation was initiated at temperatures between 200 ?220

The utilisation of biogas as an energy source or as a feed stock for the chemical industry would help to lower the present wasteful and environmentally unfriendly venting of greenhouse gases to the atmosphere.

As a potential alternative to supported nickel catalysts, a nickel doped perovskite has been produced via a hydrothermal synthesis method for reforming biogas. The selected perovskite, SrZrO3, was d

Abstract:

Hydrogen is considered as a clean energy carrier that can be converted to electricity by fuel cell with high efficiency. To be economically feasible and comparable, hydrogen needs to be liquefied, compressed, or adsorbed in metallic hydrides in large scale prior to the transfer. This requires very high pressure or very low temperature, which make a very high risk during transfer and delivery. Hence, it is highly beneficial to produce and consume pure hydrogen at the same place/time. The use of renewable biofuels such as bio-ethanol as a source of hydrogen is highly beneficial due to the higher

Abstract:

The highly competitive market in the oil refining industry forces refiners look for more detailed information of both feedstocks and products to achieve the optimal economic performance. Due to stricter environmental legislations, the molecular level characterisation has been investigated by various researchers and shows promising advantages in modern refinery design and operation. Although various molecular characterisation methods have been developed, there is an unavoidable trade-off between keeping astronomical molecule details and practicality in industrial applications. In the meantime,

Abstract:

Production of high-quality syngas from biomass gasification in a dual fluidised bed gasifier (DFBG) has made a significant progress in R&D and Technology demonstration. An S&M scale bio-automotive fuel plant close to the feedstock resources is preferable as biomass feedstock is widely sparse and has relatively low density, low heating value and high moisture content. This requires simple, reliable and cost-effective production of clean and good syngas. Indirect DFBGs, with steam as the gasification agent, produce a syngas of high content H2 and CO with 12-20 MJ/mn3 heating value. The M

Abstract:

Reforma catalítica de nafta é um dos processos mais importantes para a produção de gasolina de alta octanagem, hidrocarbonetos aromáticos e hidrogênio na indústria de petróleo e petroquímica. Para predizer os rendimentos e as propriedades dos produtos ou mesmo melhorar as condições de processo é recomendado descrever o processo matematicamente em termos de modelos cinéticos. A nafta tem um grande número de compostos com número de carbonos variando de cinco a doze, assim, um modelo considerando todos os componentes e reações, é complexo. Modelos baseados em lumps costumam agrupar os compostos e
