Fly ash has been converted to zeolite using alkali fusion followed by hydrothermal treatment. The prepared catalyst has demonstrated good efficiency in catalytic cracking of pure components, like n-Heptane, as well as heavy gas oil. The cracking and alkylation reactions were carried out in a fixed bed down flow reactor and also in batch reactor. The outcome of the present study is very much promising in utilizing a waste material into a commercial commodity and also to protect environmental pollution to some extent. The cracking activity of synthesized catalyst showed comparable activity with 13X zeolite and FCC catalyst collected from Bharat Petroleum Corporation Ltd. , India. The activity of the synthesized catalyst has been tested for lkylation of phenol. The synthesis conditions were optimized to obtain highest conversion of fly ash to X-type zeolite. Kinetic models were developed for both for cracking and alkylation reactions and kinetic parameters and adsorption constants were estimated using a non-linear regression algorithm. The prepared catalyst has been found to be superior to the commercially available catalyst like 13X and H-Beta.

Приемы комического в языке произведений П.Г....
Умело употребленный перифраз помогает автору выразить скрытый смысл, не прибегая к посторонним средствам. ‘Wha ghas ly garbage he used o fli g a us whe we were servi g our se e ce a Malver House!’ Выражение o serve se e ce означает - u dergo a period of impriso me . Поэтому, будучи применено к школьным годам, довольно ясно дает понять, что время, проведенное в Маlver House не является одним из радостных воспоминаний детства. Не редки случаи, когда Вудхауз комбинирует несколько различных приемов, чтобы фраза зазвучала живо и оригинально. Вот как описывается одна из комнат. for a Bri kly, as a mos cou ry houses, a y old ook or cra y is co sidered good e ough for he celiba e co ige . Здесь для перифраза слова room использована часть идиоматического выражения search every ook a d cra y (look everywhere, i every li le crack a d cor er). Celiba e co i ge является перифразом si gle gues . Это словосочетание составлено из слова celiba e (u married perso , especially a pries who has ake a vow o o marry) и co i ge (body of roops, umber of ships, le or supplied o form par of a larger group).

Synthesis, Microscopy, and Modelling Ultramarine Pigments from Fly Ash. Книга по Требованию Andreas L.
For sulphur chains with two and three sulphur atoms, the singly charged species are the most stable, supporting the hypothesis that the exothermic transition from green to blue ultramarine is the transformation of the doubly charged species to the singly charged species. [A specotroscopic study leads to the counter-conclusion that the yellow to blue transition is the disulphide to the trisulphide transition. ] For the single charged chain with three sulphur atoms the open chain is more stable than the closed triangle.
