Jatropha Biolubricant

750 Words3 Pages

Ghazi et al. (2012) studied the kinetics of jatropha biolubricant from transesterification of jatropha curcas oil. He studied in details the effects of temperature on the synthesis at a range between 120 0C and 200 0C with pressure kept at 10 mbar. The conversion of JME to jatropha bio-lubricant was found to be the highest (47%) at 200 0C. Historically, lubricants have been produced from both edible and non-edible vegetable oils. Vegetable oils in general posses, high viscosity index, high flash point, low evaporative loss and high lubricity compared to mineral based oil. Bio-lubricant also known as bio-based lubricant or bio-lubes are made from a variety oils of edible and non-edible seeds such as rapeseed, sunflower, soybean palm, coconut oil, castor, mahua etc. Belafi et al. (2004), on his work entitle “Manufacture of an environmental-safe biolubricant from fusel oil by enzymatic esterification in solvent-free system” observed that the oleo-chemical ester produced doesn’t have aquatic toxicity and also the determined tribologycal and physico-chemical properties of the lubricant proved biodegradability and an environmental friendliness although enzymatic esterification processes are quite complex and expensive. …show more content…

(2014), has studied on Synthesis and characterization of bio lubricants from tobacco seed oil. The work mainly reveals about structural modification namely esterification of fatty acids present in tobacco oil. The esterified products were thus examined by GC-MS for confirming the desired structure of fatty acid esters. Tribological study of the esterified products was done using pin on disc tribometer. The bio based grease had excellent co-efficient of friction compared to Hindustan Petroleum all-purpose grease NLGI grade 3 which proves it as potential base stock for biolubricant. Thermogravimetry analysis results showed that fatty acid esters had far more thermal stability than Hindustan Petroleum all-purpose grease NLGI grade

  • Summary Of Industrial Food Pollan

    523 Words  | 3 Pages

    I found Pollan 's book to be very informative and enjoyable to read. I particularly liked the fact that I could associate Pollan’s cultural, political and economic views to the topics we covered in class. In order to complete this assignment, I selected Part 1 of the book "Industrial Food" because I was particularly captivated by the secrets of corn and also because I believed that this section sincerely disclosed the reality behind High-Fructose Corn Syrup (a major participant in the development of obesity). Not only that but, the fact that corn is found in almost every product in our pantry, it’s a little frightening.

    A hydrilla grows a long steam that has many leaves on it as well as tiny white flowers on them which float above the water. They are an aquatic plant which means they live in water such as clean water, including lakes, ponds, rivers, streams, and marshes. Seen mostly in the Southeast of Florida and in their habitat they form dense mats of vegetation, can grow with little light, and more efficent in taking nutrients than other species. Florida faces many problems within their water bodies and waterways. The aquatic plants pollute 96% of the public lakes and rivers.

    In recent readings about Cyntoia Brown, who according to Willingham, previously was a victim of human sex trafficking, is now serving a life sentence for murder. The source reports that Brown suffered from Fetal Alcohol Syndrome, grew up in an abusive home and ran away from her adoptive parent’s house prior to becoming involved in prostitution in Nashville. She was staying with different people and using drugs and alcohol. As a runaway, she then met a 24-year-old pimp named "Cut Throat," who eventually began physically and sexually abusing her, and forced her into prostitution according to Willingham. The article states that on August 7, 2004, Brown testified she was solicited for sex by 43-year-old Johnny Mitchell Allan, who picked her up near a Sonic parking lot and drove her back to his house.

    In this chapter, I chose to write about Hytapia Belicia Cabral. I think Diaz wants the audience to know details about Belicia's life, struggles, hardship, and why she is they way she is. Belicia had a difficult life growing up without a father, mother, and her two sisters. Her father, mother, and two sisters passed away while Rafael Leonidas Trujillo Molina was the dictator of the Dominican Republic. What I like about the character Belicia is that she wanted to become independent at a young age.

  • In Defense Of Food Pollan

    Just reading the title of In Defense of Food (2008) by Michael Pollan gave me some hope that he would tell us that enjoying our food without guilt is all we need to know. In a sense he does just that, but first he defines what food is and is not and then goes on to explain how to find, and enjoy, this food. My first question is why people feel the need for someone to tell them what to eat. In fact, Pollan himself asks this question. Throughout the book, he spends a great deal of time defending why he wrote the book.

    Ever wonder why Santa Claus wears a red and white suit, owns flying reindeer and works with magical elves? Researchers believe these are examples of the influence of psychedelic mushrooms on Christmas tradition. Ethnobotanist and mystic Terence McKenna writes, “An example of how a very ancient folkway being incorporated into our culture without even realizing it is provided by discussing Amanita Muscaria.” Amanita muscaria is a red and white colored psychoactive basidiomycete fungus and mushroom with potent hallucinogenic properties. Popularized images of Amanita muscaria in faery tales and books like Alice in Wonderland had their origins in tribal belief systems pre-dating Christianity.

    The Detroit image of the abandoned warehouse coveys what the oil industry chooses to reveal to the public. Edward Burtynsky’s Fisher Body Plant #1 photo taken in Detroit, Michigan depicts an abandoned building that has graffiti and trash covering the worn, brick wall with broken glass windows on the upper third of the photo. The bottom third of the photo is a puddle of water that stretches to the edge of the photo and reflects the building in the water. The water in the lower third can be interpreted as oil as it looks black and murky like oil and the broken building represents the oil industry. The “oil” only reflects a select part of the building and more specifically it reflects the transition between brick and glass.

    The plant Papaver somniferum, better known as opium poppy, is a species of plant from which poppy seeds are grown and opium is made. Opium is one of the main ingredients in drugs, including heroin. The plant produces white and red flowers growing on a central bulbous pod, but with other subspecies in the family, color on the flowers varies. The pod produces a milky latex that is processed to make psychoactive phytochemical. Incisions are made on the green seed pods, the latex which oozes from the incisions is collected, and dried to produce "raw opium".
