Carbon dioxide reforming of methane produces synthesis gas with a low hydrogen to carbon monoxide ratio, which is desirable for many industrial processes. This reaction also has very important environmental implications since both and contribute the greenhouse effect. Converting these gases into valuable feedstock may significantly reduce atmospheric emissions CO2 CH4. In this paper, we present comprehensive review on thermodynamics, catalyst selection activity, mechanism, kinetics reaction....
A comprehensive study was conducted on mesoporous MCM-41. Spectroscopic examinations demonstrated that three types of silanol groups, i.e., single, (SiO)3Si−OH, hydrogen-bonded, (SiO)3Si−OH-OH−Si(SiO)3, and geminal, (SiO)2Si(OH)2, can be observed. The number groups/nm2, αOH, as determined by NMR, varies between 2.5 3.0 depending the template-removal methods. All these groups were found to active sites for adsorption pyridine with desorption energies 91.4 52.2 kJ mol-1, respectively. However,...
The discovery of mesoporous molecular sieves, MCM-41, which possesses a regular hexagonal array uniform pore openings, aroused worldwide resurgence in this field. This is not only because it has brought about series novel materials with various compositions may find applications catalysis, adsorption, and guest−host chemistry, but also opened new avenue for creating zeotype materials. paper presents comprehensive overview recent advances the field MCM-41. Beginning chemistry...
The inability of membranes to handle a wide spectrum pollutants is an important unsolved problem for water treatment. Here we demonstrate desalination via membrane distillation process using graphene where permeation enabled by nanochannels multilayer, mismatched, partially overlapping grains. Graphene films derived from renewable oil exhibit significantly superior retention vapour flux and salt rejection rates, antifouling capability under mixture saline containing contaminants such as oils...
Abstract This article presents mathematical models to simulate coupled heat and mass transfer during convective drying of food materials using three different effective diffusivities: shrinkage dependent, temperature the average those two. Engineering simulation software COMSOL Multiphysics was utilized model in 2D 3D. The results were compared with experimental data. It is found that temperature-dependent diffusivity predicts moisture content more accurately at initial stage drying, whereas...
We report the first comprehensive review of industrial process for catalytic partial oxidation methanol to formaldehyde using silver catalyst. Formaldehyde remains a key, large volume chemical which is ubiquitous household, commercial, aviation, pharmaceutical and automotive products due its high reactivity versatility. Critical analysis various technological approaches used manufacture formaldehyde, characteristics catalysts employed, conditions, performance values has been presented. The...
Intermittent microwave convective drying (IMCD) is an advanced technology that improves both energy efficiency and food quality in drying. Modeling of IMCD essential to understand the physics this process optimize power level intermittency during However, there still a lack modeling studies dedicated IMCD. In study, mathematical model for was developed validated with experimental data. The showed interior temperature material higher than surface IMCD, temperatures fluctuated redistributed...
This study aims to investigate the preparation of zeolite-based geopolymer composites incorporating blast furnace slag at various temperatures and varying amounts as potential sustainable building construction materials. The primary objectives were use mining waste streams for production assess mechanical behavior these hybrid geopolymers, along with performing a life cycle assessment (LCA) compare their environmental impact conventional concrete. It was observed that geopolymers attained...
Summary Drying is a popular food preservation technology that reduces waste and promotes security. Though drying microbial growth increases shelf life of fruits, it alters sensory properties both favourably unfavourably depending on the nature process applied significantly influences final product quality. However, there currently no review article impact sensorial quality attributes tropical fruits. This attempts to describe relative merits challenges some widely used advanced techniques...
