A fluidized bed reactor (FBR) is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions. In this type of reactor, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst) at high enough speeds to suspend the solid and cause it to behave as though it were a fluid.
Ebullated bed reactors are a type of fluidized bed reactor that utilizes ebullition, or bubbling, to achieve appropriate distribution of reactants and catalysts.The ebullated-bed technology utilizes a three-phase reactor (liquid, vapor, and catalyst), and is most applicable for exothermic reactions and for feedstocks which are difficult to process in fixed-bed or plug flow reactors due to high ...
U.S. stock indexes were split on Monday as gains for oil-and-gas producers helped offset drops for Nvidia and other Big Tech companies. The Dow Jones Industrial Average climbed 358 points, or 0.9% ...
In designing a circulating fluidized bed, with constant temperature distribution for either endothermic or exothermic reactions, in order to determine the appropriate design for cooling or heating of the circulating fluidized bed reactors, a good approximation of heat transfer rates are necessary for better control so that the reactor can ...
Indexes closed lower on Tuesday, led by a slide in tech stocks. The Nasdaq dropped almost 2%, while the Dow lost more than 150 points. Data showed strong growth in the services sector last month ...
The stock rose more than 4% to close at $143.71. Analysts have been feeling bullish on the stock's prospects for further gains amid big demand for its new Blackwell chips.
Oldest power station utilizing circular fluidized bed technology, in Lünen, Germany. A fluidized bed is a physical phenomenon that occurs when a solid particulate substance (usually present in a holding vessel) is under the right conditions so that it behaves like a fluid. The usual way to achieve a fluidized bed is to pump pressurized fluid ...
The Dow closed slightly higher on Thursday while the Nasdaq and S&P 500 closed lower in the second day of a so-called Santa Claus rally period. Stock market today: Indexes close mixed as traders ...
