| JiHua' s a -alcohol plant is one of ethylene and down-stream project,of which adopted was Ziegler process licensed by Vista of the United States,and the aluminium powder plant by Pechinery of France.The plant was put into operation in 1997and stop in 1998,because of the down market and high cost.In order to reactivate the unused assets.JiHua has decided to revamp the plant by means of utilizing the existing facilities with an accomplished olefin process,or the synthetic process of a - olefin .This study ,in term of technology and economy of a - olefin at present,analyzes the technical status,developing tendency and market at home and abroad.Having compared the different scenarios.JiHua has paid a keen attention to reviewing Linear-1 process by UOP and Versipol bby Dupont of the United Statea.lt has come to a conclusion that Linear-1 process is comparatively developed with a good stability of catalyst,a sound selection, and an adjustable distribution at a very low cost,and Versipol wwith a high activity of catalyst,a good thermo stability(110 C), a rapaicl reaction, a sound selection(secelection of a-olefine 99%),and a reasonable k-value distribution.As introducted by the above abstract,the study has been proved to be a technical and economic guarantee for the final approval by JiHua ' s administration.
