High Regeneration

The spatial distribution of V and Ni deposited within fluidized catalytic cracking (FCC) catalyst is studied because these metals contribute to catalyst deactivation. Y zeolite in FCC microspheres are high SiO2 aluminosilicates with molecular-sized channels that contain a mixture of lanthanoids. They must withstand high regeneration temperatures and retain acid sites needed for cracking of hydrocarbons, a process essential for efficient gasoline production. Zeolite in combination with V to form vanadates, or less diffusion in the channels due to coke formation, may deactivate catalyst. Other factors such as metal "skins", microsphere sintering, and attrition may also be involved. SEM of FCC fracture surfaces, AEM of Y zeolite, and electron microscopy of this work are developed to better understand and minimize catalyst deactivation.

In the present work, the pyrolysis of polypropylene and polyethylene was evaluated with and without the addition of niobium oxide as catalyst by means of thermogravimetric analysis and experiments in a glass reactor. The results revealed that niobium oxide performed well in the pyrolysis of both polypropylene and polyethylene separately. For the mixture of polypropylene with polyethylene, the catalyst reduced the pyrolysis time.

The Status

Waste is generated by various day to day human activities. Adopting improper waste handling and disposal methods can harm the well-being of public and environment. Waste management creates new opportunities for entrepreneurs in terms of social causes and it affects the economic structure and economic status of any country. One of the new approaches in waste management and income generation is Social entrepreneurship. But in Bharat i.e. India the young entrepreneurs have a dearth of consciousness towards social entrepreneurship. This paper discusses the status of solid waste management in India and Government initiatives for managing Solid Waste at Dharamshala. The main objectives of study are 1) to check awareness of people in managing solid waste at Dharamsala 2) and how to convert the plastic waste into theme based parks as skilled initiative for entrepreneurs at tourist spots in Himachal Pradesh. The paper thus explores the scope for entrepreneurs in waste management. The study reveals that Solid waste management concept attracted the attention of government around 1970s. But till now we believe in filling the waste in the ground or putting them in the dustbin. Government of India has created few acts and rules on waste management which are listed in this paper. Through this study it is revealed that people of Dharamshala welcome to the construction of themed parks made from plastic bottles. Majority of these people believe in separating waste at home and according to them conditions of waste disposal at Dharamshala are not very good. There is a positive correlation between people’s opinion of constructing theme parks and using plastic bottles in park’s construction. Study believes that the quantity of plastic waste in our country is endless which creates lot scope and opportunity to the social entrepreneurs.

Methanol To Hydrocarbons

The catalytic activity of Na, H-Y zeolite samples with a varying Si/Al ratio (2·5 to 20) in the transformation of methanol was determined. The amounts of formed individual aliphatic hydrocarbons as function of reaction time were correlated with the amount of Bronsted and Lewis centres on the catalysts. The effect of coke formation on the over-all course of the reaction has been demonstrated.
