The control followed similar process trends as in batches IIII but without enzyme treatment. The following analyses were carried out for the recovered juice. The percentage juice recovery and Total Phenolics () were estimated for each batch after dual extraction, while o Brix, Titratable Acidity (), turbidity and viscosity were done for each step of extraction.

Pros and Cons of Coal Mining Vision Launch The pros and cons of coal mining may offer an economic benefit, but at a disadvantage to the environment. We are still going to use coal to heat our homes and have access to power, but if we can limit how much coal is needed, we could have a huge impact on the world for future generations.

Ostwald Process for Making Nitric Acid. In the Ostwald process, nitric acid is made from ammonia. What's happening here is ammonia is producing nitric acid. Now, as you can see, the process isn't quite that simple. Nitric acid is made from ammonia in three steps. Starting out, we have ammonia.

Producing nitric acid: The Ostwald process The Ostwald process is used to produce nitric acid from ammonia. Nitric acid can then be used in reactions that produce fertilisers. Ammonia is converted to nitric acid in a threestep process. Firstly ammonia is oxidised by heating it with oxygen, in the presence of a platinum (Pt)

In 1914, a German chemist Ostwald developed the Ostwald process to manufacture nitric acid. Step 1: Catalytic oxidation of Ammonia. A mixture of dry air and dry ammonia in the ratio of 10:1 by volume is compressed and then. passed into a platinum gauze which acts as catalyst at about 800°C. 4NH 3 + 5O 2 → 4NO +6H 2 O +Heat

Ultrasound is known to synthesize MOFs rapidly under mild process conditions, such as solventfree, at room temperature and under ambient pressure. Studies have shown that MOFs can be produced costeffectively at high yield via sonochemical route. Finally, the sonochemical synthesis of MOFs is a green, environmentally friendly method.

Before the Ostwald process was developed the only source of nitrates for use in explosives was naturally occurring minerals such as saltpeter, which is a mixture of NaNO 3 and KNO a dependable supply of nitric acid became available from the Ostwald process, a number of nitrates could be made for use as explosives.

Feb 05, 2010· Nitric acid is produced commercially by the Ostwald process. The three steps of the Ostwald process are shown in the following equations. 4 NH3(g) + 5 O2(g) → 4 NO(g) + 6 H2O(g) 2 NO(g) + O2(g) → 2 NO2(g) 3 NO2(g) + H2O(l) → 2 HNO3(aq) + NO(g) What mass of NH3 must be used to produce 106 kg HNO3 by the Ostwald process, assuming yield in each reaction?
