Review and comparison of the methodology adopted for biodiesel production

Carbon Resources Conversion
Biodiesel is a versatile energy source synthesized by trans esterifying various edible or nonedible oils using catalysts. It is preferable to diesel because of its higher flash points, reduced sulphur content, and biodegradability. Biodiesel synthesis by

Cleaner Routes for Friedel-Crafts Acylation [PDF]

, 2010
Friedel-Crafts acylation is among the most fundamental and useful reactions to yield aromatic ketones but it is one of the less acceptable in terms of unwanted polluting by-products or atom economy because of the overconsumption of catalyst which is used

Advancements in CO2 Capture Technologies: A Review of Amine Absorption and Alternative Methods for Post‐Combustion Integration

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Carbon capture technologies are poised to become one of the primary focuses regarding the achievement of net‐zero emissions by the year 2050. In these technologies, particular attention is given to post‐combustion CO2 capture, which is more easily implemented at existing power stations and other industries.

PEG Alternatives in Liposomal Nanocarriers: Physicochemical Characteristics and Sustainable Process Strategies

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The global trend toward sustainable and intensified bioprocesses is driving innovation in the design and scalable synthesis of liposomal nanocarriers, a cornerstone of modern drug delivery. For decades, these nanosystems have relied exclusively on polyethylene glycol (PEG) for their sustained circulation in vivo, but they are currently ...

Synergetic Combination of Carbon Xerogels, Graphene Oxide and nano‐ZnO for Aqueous and Organic Supercapacitors

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.

Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater

Chemie Ingenieur Technik, EarlyView.
This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...
