The flow of spent catalyst to the regenerator is regulated by a slide valve in the spent catalyst line. Since the cracking reactions produce some carbonaceous material (referred to as catalyst coke) that deposits on the catalyst and very quickly reduces the catalyst activity, the catalyst is regenerated by burning off the deposited coke with ...
Needle coke, also called acicular coke, is a highly crystalline petroleum coke used in the production of electrodes for the steel and aluminium industries and is particularly valuable because the electrodes must be replaced regularly. Needle coke is produced exclusively from either fluid catalytic cracking (FCC) decant oil or coal tar pitch.
The "spent" catalyst then flows into a fluidized-bed regenerator where air (or in some cases air plus oxygen) is used to burn off the coke to restore catalyst activity and also provide the necessary heat for the next reaction cycle, cracking being an endothermic reaction. The "regenerated" catalyst then flows to the base of the riser, repeating ...
In 2008, Albemarle acquired Sorbent Technologies Corporation, [22] whose technology controls mercury emissions from coal-fired power plants, for $22.5 million. [23] [24] In 2009, Albemarle and TAYF, an affiliate of SABIC, created a catalysts joint venture to build a world-scale organometallics production facility in Jubail. [25]
A 4-drum delayed coking unit in a petroleum refinery. A delayed coker is a type of coker whose process consists of heating a residual oil feed to its thermal cracking temperature in a furnace with multiple parallel passes.
Coca-Cola Bottling Co. Consolidated, COKE on the stock market, is the largest in the U.S., selling soft drinks in 14 states and Washington, D.C. Which Investment Is Smarter: KO vs Coke Stock?
The back of Coca-Cola's proxy statement recently stopped me in my tracks. It declared that just one $40 share of the company's stock bought in 1919, with dividends reinvested, would be worth $9.8 ...
The 1950s Kellogg technology expanded into steam pyrolysis, Orthoflow fluid catalytic cracking, phenol-from-cumene and coal-to-synthetic fuels technologies and the 1960s saw the growth in helium recovery, ethylene, and the development of Kellogg's ammonia process.
