For the reactive flash volatilization (RFV) process based on the knowledge that the catalyst bed is preheated to high temperature, pyrolysis of the heated cellulose particles on the surface of the bed is expected to be fast enough that it will not be a rate-limiting step. Hence, the kinetics of the RFV of cellulose reduces to gasification of the produced volatile organic compounds (VOCs) on and in the catalyst bed. To represent the RFV of the VOCs from flash pyrolysis of cellulose, Aspen Plus…

Batch adsorption experiments Adsorption of the Pb2+ ions by the Fe3O4@GMA-AAm nanocomposite was measured from batch adsorption experiments by mixing 10 mg of adsorbent with an aqueous solution containing a predetermined concentration of Pb2+ ions (50 mL). The mixture was shaken at 200 rpm to reach equilibrium. After a specified time, the solid and liquid were separated by external magnet and the concentrations of Pb2+ ions were measured by AAS. To find the optimized pH in adsorption of Pb2+ ions…

Thermal energy strorage Thermal Energy Storage is the temporary storage of high or low temperature energy for later use, bridging the gap between requirement and energy use. The storage cycle might be daily, weekly or seasonal depending on the system design requirements, and whilst the output will always be thermal, the input may be thermal or electrical. Principle 1) Sensible Heat Storage Heating a liquid or solid, without changing the phase: This method is called sensible heat storage.…

The E-factor Review: Are you one of them who are affected by the start of obesity? Search a way to drop fat the pounds & keep them stop forever? Have you been search a new method to lose weight? Original & insightful, The E-Factor Diet has been formed with the mission of assist reverse the pandemic of fatness taking the world population. That is the most rewarding matter if one has a healthy physique. It does not just keep you energetic & active long day but also assist in keeping you in a…

methane It is essential to understand the thermodynamic of CDRM represents as follow: CH_4+CO_2 □(→) 2CO+〖2H〗_2 ∆H_298=247 KJ⁄(mol ) (1) ∆G^o=61770-67.32 T This reaction above is highly endothermic which is favored by low pressure but, requires a higher temperature. A reverse water-gas shift reaction occurs as a side reaction as below CO_2+H_2 □(→) CO+H_2 O ∆H_298=41 KJ⁄(mol ) …

Canis lupus familiaris (dogs) were likely the first animals to be domesticated by humans. Humans and dogs share a long intertwined history. DNA evidence suggests domestic dogs most likely diverged from wolves as long as 135,000 years ago (Udell and Wynne). The American Kennel Club (AKC), a registry of purebred dog pedigrees in the United States, recognizes 167 breeds. Being that dogs are one of the most common household pets owned by humans, it is important to understand their physiology for…

of 1966 was established to create satisfactory standards for the treatment of animals. Animals used for research should be protected by the Animal Welfare Act, however, the animals excluded from this act are birds, rats, mice, farm animals, and endothermic animals. As a result, a tiny percentage of animals used in research are actually protected under this act. As important as it is to bring attention to this problem, it is also very essential to mention that, even though they are not protected…

Trees naturally sequester atmospheric carbon dioxide through photosynthesis and thus decrease global warming and its repercussions. Carbon dioxide is an essential component of the Calvin Cycle for the production of glucose, which is the primary energy source for plants as well as many herbivorous and carnivorous consumers. With the rapid increase in atmospheric carbon dioxide levels from anthropogenic activity since the Industrial Revolution, scientist suspect that carbon dioxide fertilization…

(a) Langmuir isotherm model Langmuir isotherm is based on the following assumptions: (a) each surface site can be singly occupied, (b) there are no lateral interactions between adsorbed species, (c) the enthalpy of adsorption is independent of surface coverage and (d) energy of adsorption is constant. The Langmuir isotherm is 2.5…

Prologue: The prologue chapter introduces biology and it’s meaning. It states the difference between pseudoscience and testable science. For example, evil forces do not kill the living contents in the biosphere nor do the gods help keep it alive. Instead, the biosphere is based on scientific explanations from observations, inferences, and experiments. In these experiments, there are testable hypotheses, such as whether your plant will die or why the plant grew to the top of the bottle.…
