Determining the fouling tendency of different feedstocks in the Fouling Assessment Setup
The use of heavier feedstocks, or even the possibility of direct conversion of crude oil into chemicals has created new challenges for the steam cracking process, as severe fouling in the different sections of steam crackers is observed then. In order to obtain a more fundamental understanding about the fouling phenomenon and its relation to feedst...
Effect of reactor alloy composition on coke formation during butane and ethane steam cracking
The use of highly specialized alloys in ethane steam cracking environments can lead to reduced coking and alloy aging. However, the fouling resistance of these materials when exposed to heavier feedstocks, such as butane, especially at higher temperatures (950 degrees C) and toward the end of a cracking run, remained unknown. To address this knowle...
Synthesis, characterization, and methylene blue adsorption isotherms of hydrochars derived from forestry waste and agro-...
Mason pine-derived hydrochar (MPHC), cedarwood-derived hydrochar (CHC), bamboo-derived hydrochar (BHC), coconut shell-derived hydrochar (CSHC), pecan shell-derived hydrochar (PSHC), wheat straw-derived hydrochar (WSHC), maize straw-derived hydrochar (MSHC), and rice straw-derived hydrochar (RSHC) were synthesized by hydrothermal carbonization (HTC)...
Comparative study on the effect of ZnCl2, a 60:20:20 mol % eutectic of ZnCl2-NaCl-KCl and CO2 during activation of pinew...
Chemical activation in molten salts is a recent development in the field of tailoring activated carbon, where a combination of activating agents is used rather than a single compound. However, a comprehensive understanding of differences in catalytic activity is lacking. So, the question remains which chemical activation method is more beneficial. ...
Evaluation of South Korean marine waste resources for hydrochar production : effect of process variables
This study assessed the hydrochar production potential of fish and crustacean waste from 8 marine species (Scomber japonicus, Trichiurus lepturus, Larimichthys polyactis, Trachurus trachurus, Paralichthys olivaceus Litopenaeus vannamei, Portunus trituberculatus, and Penaeus monodon) through hydrothermal carbonization (HTC) of their waste fractions....
Enhancing sustainable waste management : hydrothermal carbonization of polyethylene terephthalate and polystyrene plasti...
Hydrothermal carbonization (HTC) of single plastic polymers such as polyethylene terephthalate (PET) and polystyrene (PS) has not yet been explored on a large scale, particularly their thermal behavior, chemical transformations under subcritical conditions, and the energy properties of the resultant hydrochar. This study investigated these aspects ...
Computational fluid dynamics simulation of a high-throughput catalytic fixed-bed reactor for total oxidation of methane
This paper presents a two-dimensional computational fluid dynamics (CFD) study to investigate the performance of our high-throughput fixed-bed reactor used for the total oxidation of diluted volatile organic compounds (VOCs) in a continuous gas stream. The CFD model, based on a porous medium and a power-law kinetic model, is validated by comparing ...
Production of solid hydrochar from waste seaweed by hydrothermal carbonization : effect of process variables
This study provides a comparison of hydrothermal carbonization (HTC) char, starting from two different species of waste seaweed, namely the green algae Ulva pertusa and the brown algae Sargassum horneri. The effect of reaction temperature (180 similar to 250 celcius), biomass residence time (1 similar to 6 h), and water mass ratio (1 similar to 10)...
