Abstract (sommario):

This article discusses the results of a study of the process of catalytic reforming of straight-run gasoline obtained from a mixture of oil from a field located in the southern region of Kazakhstan. The individual and group hydrocarbon composition of the initial hydrotreated gasoline and reformate was studied in order to establish the degree of conversion of hydrocarbons at different stages of catalytic reforming. The qualitative characteristics of the catalysis of gasoline reforming obtained at different stages of the process allows us to establish the chemistry and reaction mechanism and the

Abstract (sommario):

Synthetic gas - a combination of (H2) and (CO) - is an important chemical intermediate for the production of liquid hydrocarbon, olefin, gasoline, and other valuable chemicals.

Abstract (sommario):

Catalytic reforming is a chemical process used to convert low-octane naphtha's into high-octane gasoline blending components called reformates to be used either as a motor fuel blending stock or as a source for specific aromatics, such as benzene, toluene and xylene (BTX). Considering the importance of this process for the production of gasoline, the catalytic reforming process is simulated and important parameters such as octane number, reactor inlet and outlet temperatures, and PONA moles of the gas leaving the reactor are predicted.

Abstract (sommario):

Methane reforming is the most feasible techniques to produce hydrogen for commercial usage. Hence, dry reforming is the environment friendly method that uses green house gases such as CO2and methane to produce fuel gas. Catalysts play a vital role in methane conversion by enhancing the reforming process. In this study Ni/γ-Al2O3was selected as based catalyst and CeO2and Fe2O3dopants were added to investigate their effect on catalytic activity in dry reforming. The catalysts synthesized through wet impregnation method and characterized by using XRD, TEM and SEM-EDX. The catalytic tests were car

NiCuMoLaAl mixed oxide catalysts are prepared and applied in the steam reforming of chloroform-ethyl acetate (CHCl3-EA) mixture to syngas in the present work. The pre-introduction of Cl- ions using chloride salts as modifiers aims to improve the chlorine poisoning resistance. Catalytic tests show that KCl modification is obviously advantageous to increase the catalytic life. The destruction of catalyst structure induced by in situ produced HCl and carbon deposits that occurred on acidic sites are two key points for deactivation of reforming catalysts. The presence of Cl− ions gives rise to the

Abstract (sommario):

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

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

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.

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

Abstract (sommario):

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. One obstacle to this becoming a reality include finding a catalyst that is active towards carbon dioxide reforming of methane as well as resistance to carbon deposition and sulphur poisoning. 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 Severe internal attack was experienced in the hottest part of 2.25Cr 1Mo steel charge heater tubes in a Continuous Catalyst Regeneration (CCR) Platformer unit. The metal loss was found to be caused by so-called metal dusting. Metal dusting can occur due to the high carbon activity in the CCR process gas. If active metal surfaces are exposed to this gas at relatively high temperature levels of about 625 to 675 °C, metal dusting might occur whilst forming whisker-type graphite. The temperature range for metal dusting is very narrow, in CCR process gas it can occur over a range of about
