    CO2 Concentration Essay

    • 784 Words
    • 4 Pages

    One of the most widely studied mitigation options for reducing concentration of CO2 in atmosphere involves injecting it into the ocean at great depths, where the gaseous CO2 reacts to form carbonic acid (H2CO3) as shown in equation (2.1). This equation shows various forms of CO2 as it is dissolved in the water (brine). Depending on the pH of the solution, either forms of CO2 may be observed (CO2 (aq), 〖"HCO" 〗_"3" ^"-" , 〖"CO" 〗_"3" ^"2-" ). There are two ways for storing CO2 in ocean, either…

    1.4.2.2 Oxidizer The oxidizer is an another basic ingredient of solid propellant which produces high energy during combustion of composite solid propellants, which can be referred to as the substance that whose function is the oxidizing materials or supply of oxygen for deflagration of a propellant. Ammonium perchlorate (AP) is the most commonly used oxidizer in solid propellant applications, which replaced Potassium Perchlorate in the late 1940’s. AP was used as an oxidizer in various types of…

    Biodiesel production is usually expressed through the process of trans-esterification reaction. Recently, homogeneous catalysts are broadly preferred for biodiesel production in eminent scale operation. Still, they are toxic, highly flammable and corrosive in nature [1]. Boey et al. analysed the purpose of the waste cockle shell from palm olein oil in biodiesel production of Anadara granosa. At 900 °C the waste shell was calcined for 2 h that mainly compiled of 71% of Ca to develop an active…

    Essay On Carbon Cycle

    • 909 Words
    • 4 Pages

    The Carbon Cycle Addition of carbon to the atmosphere Respiration: Through respiration, carbon dioxide can be added to the atmosphere. Living organisms use respiration to turn food into usable energy. Aerobic respiration requires oxygen to take place, and produces carbon dioxide, releasing it into the air and atmosphere. The energy taken from the food molecules following digestion is used to fuel the organism, additionally when mixed with oxygen, releases carbon dioxide when exhaling.…

    What is a laccase? Laccases (EC 1.10.3.2, benzenediol: oxygen oxidoreductase) are monomeric, dimeric or tetrameric glycoproteins that are typically extracellular and categorized as multi copper oxidases (Mate and Alcalde, 2016a).They catalyze the oxidation of compounds that are coupled with the four-electron reduction of "O" _"2" "to" "H" _"2" "O" . They are regarded as eco-friendly enzymes. Laccases have been first discovered in 1883, which makes it one of the oldest enzymes ever observed…

    Gaseous Streams Case Study

    • 1175 Words
    • 5 Pages

    Different technologies are available for the treatment of gaseous streams containing VOCs (Volatile Organic Compounds), namely catalytic or homogeneous combustion, absorption, adsorption, etc. The goal is either to recover the VOCs, or to destroy them, thus avoiding, in both cases, their emission into the atmosphere. The treatment of “lean” streams, where the concentration of the VOCs is particularly low (e.g. lower than 1% v/v), is a particularly challenging case study as the low concentration…
