Calcns. were performed for 2 reactor variants with integrated heat exchangers for post-combustion of volatile org. substances significantly diluted in air. The goal was to achieve the efficiency of autothermal process. In variant I, thermal losses were...
Exptl. studies were conducted on a new type of structured catalytic carrier, manufactured using 3D printing. Its design was inspired by fish gills, which are natural structures with high transport properties and a large sp. surface area, characteristics...
A review, with 22 refs., of methods for modification of zeolites with metals and metal oxides to enhance their H2S adsorption capability and recyclability as well as to improve processes for H2S removal from various gaseous mixts.
Varied types of particulate matter (PM) persist in the environment and exert a harmful impact on public health. The aim of this review article is to explore the key role of membrane technology in the separation of PM from ambient air. Nanofibrous, microporous,...
Bubble columns (BCs) are widely used gas-liquid contactors in the chemical industry. Their hydrodynamic and mass transfer performance depends on the prevailing flow regime (FR) and the gas sparger (GS) type (particularly in the homogeneous FR). In this...
Membrane processes continue to attract significant interest, as reflected in the growing number of studies focused on the development of innovative membrane materials. Novel membranes are frequently designed for specific separation processes, in which...
Since fossil fuels still dominate industry and electricity production, post-combustion carbon capture remains essential for decarbonizing these sectors. The most advanced technique for widespread application, particularly in hard-to-abate industries,...
The research problem was to determine the possibility of aqueous mineral carbonation using fly ash from lignite fluidized bed combustion. Both direct and indirect routes were used. The innovative nature of the research consisted of conducting experiments...
The molar flows rates and ideal selectivities of CO2 and N2 sepn. were compared using supported ionic liq. membranes (SILMs) obtained by impregnating ceramic materials from various manufacturers with ionic liq. [Emim][Ac] (1-ethyl-3-methylimidazole acetate)...
An anal. of the developed math. model optimizing the value chain of biogas prodn. based on such parameters as substrate costs, their transportation costs, distance from the biogas plant, investment and operating costs of the biogas plant, as well as...
The growing concern over the long-term persistence of plastic waste has driven research into biological methods of breaking down polymers. This study investigated a process that combines physicochemical pretreatment and biodegradation of low-density...
In this paper, we present the results of heat transfer studies on short-channel structured packing in chemical reactors. Heat transfer coefficients, streamlines, and fluid temperatures were determined using CFD (Computational Fluid Dynamics). CFD simulations...
