The study of sulfur compounds for oils fingerprinting application

Titiparn Prasantongkolmol (Chulalongkorn University, 2019)

Oil spills are one of the serious problems to marine and coastal environment worldwide. Besides the known incidents, a number of oil spills are unknown, which may come from both accident and unauthorized drainage. Moreover, ...
Removal of trace olefins from aromatics with modified USY zeolite and clays

Sirawit Lertprapaporn (Chulalongkorn University, 2019)

Naphtha reforming is an important raw material for aromatic hydrocarbon products in petrochemical processes. However, aromatic hydrocarbon streams obtained from refinery contain unavoidable trace amounts of olefins as an ...
Stochastic supply chain optimization for ammonia and urea processes

Seangplang Srisamut (Chulalongkorn University, 2019)

To support the demand growth in the agriculture sector from increasing population, ammonia and urea productions have been continuously increasing. Methane from natural gas can be used as feedstock in the production process. ...
Silver Nano Polymer Composite Membrane for hydrogen sulfide sensing

Muhammad Bagus Arif (Chulalongkorn University, 2019)

Optical and electrochemical sensor for H2S sensing were developed using silver nanoparticles (AgNPs) immobilized onto polyelectrolyte membranes (PEMs) as substrate. Two approach for the deposition of the silver nanoparticles ...
Enhanced methane hydrate formation using promoters for natural gas storage and transportation application

Katipot Inkong (Chulalongkorn University, 2020)

Solidified natural gas (SNG) is an alternative technology for natural gas storage and transportation in the clathrate hydrate formed. It has higher volumetric energy storage with the ease to handle not to mention its safety. ...
Preferential CO oxidation in the presence of H2 over Au-based catalysts

Pattarasuda Naknam (Chulalongkorn University, 2010)

Traces amount of CO dramatically reduce the PEM fuel cell efficiency. Therefore, the removal of CO via preferential CO oxidation (PROX) is a potential method to remove CO from the EE-rich stream. Au-based catalysts are ...
Natural gas storage using clathrate technology : Enhanced formation at High temperature

Kan Jeenmuang (Chulalongkorn University, 2019)

Solidified natural gas (SNG) by storing natural gas in the hydrate form, which is safe and easy to recover stored gas compared to other methods. However, to make this technology competitive, storing natural gas at a higher ...
Production of Bio-jet fuel from palm fatty acid distillate over Bi-Functional CoPd/HZSM-12 catalysts

Jarujit Chaowichitra (Chulalongkorn University, 2019)

Jet fuel is one of the major products from a petroleum refinery, its combustion emissions contribute to global warming. Therefore, bio-jet fuel is introduced to solve this problem. Palm fatty acid distillate (PFAD) is an ...
The Mixed Integer Non-Linear Programming for Combined Heat and Mass Exchanger Network Synthesis with The Effect of EMCD and EMAT on Economic Analysis

Eleonora Amelia (Chulalongkorn University, 2019)

The Combined Heat and Mass Exchanger Network Synthesis (CHAMENS) which comprised a win-win strategy simultaneously diminishing the emission alongside maximizing the profits of the whole systems has been accomplished in ...
Influence of mixed anionic-nonionic surfactants on methane hydrate formation : suppression of foam formation

Chakorn Viriyakul (Chulalongkorn University, 2020)

Solidified natural gas (SNG) via clathrate hydrate is a new technology for natural gas storage with high energy content per unit volume, extremely safe, and ease to recover. Although SNG has several advantages, its limitation ...
Conversion of n-Pentane to light olefins over modified Zr/HZSM-5-based catalysts

Bharanabha makkaroon (Chulalongkorn University, 2020)

Ethylene and propylene are important raw materials for producing several types of chemicals and polymers. According to the increase of propylene demand in recent year, the P/E ratio was increased to 0.85. In order to meet ...
