Photocatalytic Carbon Dioxide and Methane Reduction to Fuels over La-Promoted Titanium Dioxide Nanocatalyst.

Posted on December 21, 2017 by teckhoe93

Abstract:

Selective photocatalytic carbon dioxide (CO2) reforming of methane (CH4) to carbon monoxide (CO) and hydrocarbons over lanthanum loaded titanium dioxide (La/TiO2) nanoparticles has been investigated. TiO2 nanoparticles (NPs) with different La-loadings were synthesised using sol-gel method. The catalysts were characterised using X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM) and Photoluminescence (PL) spectroscopy. Pure crystallite and anatase phase TiO2 with hindered charge recombination were detected in the La-loaded TiO2 samples. The products obtained were mainly CO, followed by ethane (C2H6) and traces of propane (C3H8). Pure TiO2 was favourable for CO evolution, while La-loaded TiO2 samples promoted hydrocarbons formation. The 2 wt% La/TiO2 photocatalyst conferred the maximum C2H6 yield of 492.8 µmole/g-cat at CO2/CH4 feed ratio 1.0 and irradiation time 2 h. The enhanced photocatalytic performance can be attributed to efficient reactant adsorption with hindered charge recombination rate in the presence of La-metal.

Ethanol Steam Reforming for Renewable Hydrogen Production over La-Modified TiO2 Catalyst

Posted on December 21, 2017 by teckhoe93

Abstract :

In recent years, ethanol steam reforming (ESR) has received considerable attention as a promising route for cleaner H2 production. This process could be industrially advantageous, ideally yielding 6 moles of H2 per mole of ethanol reacted. The major drawbacks of the process are the endothermic nature of the reaction and presence of CO2 in the product. At low temperatures (below 500 ºC), side reactions that yield alternative products such as acetic acid, acetaldehyde and ethylene are favoured. Besides promoting ESR, higher temperatures make the process costly for an industrial development while promoting CO, CO2 and coke formation, which is the main cause of catalyst deactivation. In this study, a series of La-loaded TiO2 catalysts were prepared by an impregnation-co-precipitation method, La being a well-known inhibitor of CO and CO2 formation. Catalytic ethanol steam reforming was conducted in a tubular fixed bed reactor operated at 1 atm, 500 ºC and an ethanol/water molar feed ratio of 10:1. The influence of La-loading on inhibiting coke formation and selectivity towards hydrogen formation by ethanol steam reforming has been investigated. The catalytic performance of La-loaded TiO2 catalyst was found to be considerably higher when compared to the pure TiO2. At 10 % La loading, ethanol conversion of ~27.5 % was achieved with a H2 mole fraction of 0.53. Significant amounts of valuable products such as CH4 and C2H4 were also detected in the product mixture. More importantly, CO was not detected over La-loaded TiO2 catalyst, which confirmed its ability for minimizing coke formation. This development has confirmed improved efficiency of La/TiO2 catalyst toward renewable
hydrogen production

Board of Engineers

Posted on December 18, 2017 by teckhoe93

LINKS : Boards of Engineers Website

The Board of Engineers Malaysia (BEM) is a statutory body constituted under the Registration of Engineers Act 1967 with perpetual succession and a common seal, which may sue and be sued. It was formed in 23rd August 1972. BEM primary role is to facilitate the registration of Engineers, Engineering Technologists, Inspectors of Works, Sole Proprietorships, Partnerships and Bodies Corporate providing professional engineering services and; to regulate the professional conduct and practice of registered person in order to safeguard the safety and interest of the public.

BEM falls within the ambit of responsibility of the Minister of Works. Vested with wide powers, the Minister may suspend the operation of the Registration of Engineers Act 1967 (REA) in any part of Malaysia by notification in the gazette. The appointment of the Board Members and the Registrar is made by the Minister.

The Registration of Engineers Act 1967 and the Registration of Engineers Regulations 1990 have been amended in 2015 with date of operation on 31st July 2015. The amended REA will be known as “Registration of Engineers Act 1967 (Revised 2015)’ whilst the accompanying Regulations will be known as “Registration of Engineers Regulatons 1990 (Revised 2015)”.

These latest amendments are a direct result of Government policies on trade for services. As Malaysia developed towards a service industry the issue of “liberalisation” of the services came to the forefront in the Free Trade Agreements (FTA) which the country signed. These latest amendments directly address liberalisation issues in order for the country to meet its international obligations.

The need to regulate the Engineering Team; Engineers, Engineering Technologists and Engineering Technicians has also led the BEM to amend the REA to incorporate two new categories: Engineering Technologists and Inspector of Works (also known as Engineering Technicians).

It provides guidelines on how to work professionally and become professional engineers
