Effect of Sodium Alginate Concentration on Size of Yeast Immobilized Particle and on Production of Bio-ethanol in a Packed-Bed Fermenter
Abstract: Biofuels are important because they replace the petroleum fuels or fossil fuels and especially ethanol and butanol contribute greatly to the mitigation of greenhouse gases emission, provide clean and sustainable energy source and reduce the consumption of crude oil. Current ethanol production processes using agricultural crops such as sugarcane and corn are well known, i.e., biochemical pathway and thermo-chemical pathway. However, in the biochemical pathway, the reactors used for fermentation …

Risk Assessment of Batch Sulfonation Process using Fault Tree and Bowtie
Abstract: The current study looks into the batch reactor's sulfonation reaction's safety features. Acetanilide, thionyl chloride, and chlorosulphonic acid are used in the sulfonation reaction under consideration to generate acetyl sulphonyl chloride as well as by-products such HCl and SOx. Steam starts the process, which is exothermic in nature. Water is then chilled to maintain a temperature of 50°C and a pressure of one atmosphere. The Hazard and Operability (HAZOP) analysis …

Comparative Analyses of Select Microbial Growth Inhibited Rate Models
Abstract: Food waste is a complex substrate comprising of different mixtures of chemical compounds. The growth rate of micro-organism in such environment will experience inhibition. Consequently, the Monod’s model will not be able to describe the growth rate of its bacteria. The Aiba’s, Andrews and the Haldane’s growth rate models that are accounts for growth rate of bacteria with inhibition were compared. To do this, seven different batch experimentations; each with …

The Impact of Bacteria and Biostimulants on Crude Oil Breakdown in Loamy Soil
Abstract: This study investigates the influence of bacteria and biostimulants—specifically Bryophyllum pinnatum leaves soaked in both water and ethanol—on the degradation of crude oil in loamy soil. A laboratory-scale bioremediation setup was employed using a batch reactor model and first-order degradation kinetics to assess total petroleum hydrocarbon (TPH) breakdown under controlled conditions. Various analytical tools and procedures, including gas chromatography (Agilent 6890) and microbial media such as nutrient agar and mineral …

Application of Ultrasound for Synthesis of Biodiesel
Abstract: The aim of study is to synthesize a biodiesel from soybean oil using ultrasonic process. At present, biodiesel is produced in batch reactors in which the required energy is provided by heating by mechanical mixing. Alternatively, ultrasonic processing is an effective way to attain required mixing providing the necessary activation energy. Ultrasonic is a very desirable tool for producing biodiesel from vegetable oil and animal fats, because it lowers the …

Analysis of Diethanolamide Reaction by using FTIR Technique
Abstract: The purpose of this work is to study the amidification reaction for production of diethanolamide from ethyl acetate and diethanolamine by using sulfuric acid catalyst. The amidation, which is the reaction between ethyl acetate and diethanolamine, was held in a glass batch reactor with mole ratio 1:1 using acid catalyst (H2SO4) 0.5% (w/w) and 200 rpm stirring. The reaction temperature is 160°C constant, and sampling was performed after every 30 …

Study of Crude Oil Degradation Using Bio-stimulant: The Concept of Remediation Application
Abstract: The Total Petroleum Hydrocarbon (TPH) degradation was monitored in a batch reactor with the addition of bio-stimulants of palm oil processed waste water (POPWW) and NPK fertilizer in contaminated clay soil medium. The comparative study on the performance of both bio-simulants revealed that the NPK fertilizer was more effective than the palm oil processed waste water (POPWW). This study is based on the overview on the degradation of petroleum hydrocarbon …

Fundamentals and Recent Advances in Microreactor Catalysis and Flow Chemistry
Abstract: The processing technology of chemical reactions has changed quite a bit over the last few decades. For a long time, chemists relied on batch reactors having large containers where all the starting materials are mixed, and the reaction happens in one go. While this approach works, it has several drawbacks: poor heat control, uneven mixing, safety risks, and a lot of waste. Microreactors and flow chemistry offer a much better …
