Phenol degradation over mesoporous-assembled SrTixZn1-xO₃ nanocrystal photocatalysts

Supachai Tiyawarakul (Chulalongkorn University, 2012)

Advanced oxidation processes (AOPs) are effective techniques used to efficiently degrade non-biodegradable organic contaminants present in wastewater. Photocatalysis is an AOP that is very promising in the use of solar ...
Toluene methylation over modified HZSM-5 catalysts: effect of combined silylation and dealumination

Sasithon Yeenang (Chulalongkorn University, 2015)

p-Xylene is valuable raw material for the chemical and petrochemical industries, e.g., for producing polyesters and plasticizers. Currently, p-xylene is produced by methylation of toluene and toluene disproportionation. ...
Life cycle management of bioplastic for a sustainable future: Sa-Med Island model

Sompit Petchprayul (Chulalongkorn University, 2012)

This research aimed to evaluate the environmental performance of selected bioplastic product produced from polylactic acid (PLA) and polybutylene succinate (PBS) based on life cycle approach. Raw materials used to produce ...
Dilute phosphoric acid pretreatment of corncobs for biofuels production

Sirikarn Satimanont (Chulalongkorn University, 2012)

A waste product from corn production, corncob, is one type of lignocellulosic material, which is a new targeted source of fermentable carbohydrates that can be converted into second generation biofuels. In order to convert ...
Preparation and characterization of CM-chitin/natural rubber blends

Sedthakij Udom (Chulalongkorn University, 2012)

Carboxymethyl chitin (CM-chitin), a water-soluble derivative of chitin, has several interesting biological activities, leading to its potential use in biomedical field, such as wound dressing application. However, CM-chitin ...
Synthesis and characterization of biopolymer modified with piperazine derivative for carbon dioxide adsorption

Sasithorn Srisuwanvichien (Chulalongkorn University, 2012)

A new adsorbent biopolymer which is an abundant renewable resource from the nature has been successfully modified with a piperazine derivative for CO2 adsorption. The biopolymer was purified by alkali treatment to obtain ...
Catalytic pyrolysis of waste tire over mesoporous MCM-48: influence of Si/Al ratio and double beds of Si-MCM-48 and zeolites

Sarinthip Trongyong (Chulalongkorn University, 2015)

Tire-derived oil usually consists of small amounts of petrochemicals, some large aromatic hydrocarbons and sulfur compounds. In order to improve the quality of tire-derived oil. catalysts are necessary in pyrolysis process. ...
Microemulsion based residual oil recovery for spent bleaching earth from biodiesel production

Ratiprach Aiamthongkham (Chulalongkorn University, 2015)

Spent bleaching earth (SBE), an industrial solid waste generated at bleaching process of vegetable oil refinery, usually recovers oil retained in SBE through solvent extraction which can lead to environmental impact and ...
Processing of iron nugget from low grade iron ore

Sarun Rojanakatanyoo (Chulalongkorn University, 2012)

The production of raw metals has been changed for several years. Blast furnace and gas-based direct reduction have been used to produce industrial metals from iron ore, but they have many drawbacks such as high capital ...
Kinetics of oxide formation on various steel surfaces in the presence of oxygen-nitrogen mixtures

Sarita Weerakul (Chulalongkorn University, 2012)

The formation of oxides at 400°C and 90°C with different oxygen concentration conditions on various metal surfaces; carbon steel, stainless steel and nickel-alloy was studied. From 400°C tests of carbon steel surfaces, ...
