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.
Mechanically Fluidized Reactor (MFR): A mechanical stirrer is used to mobilize particles and achieve properties similar to that a well-mixed fluidized bed. It does not require fluidization gas. [7] Narrow fluidized beds (NFB): For this case, the ratio between the tube and the grain diameters is equal or less than around 10. The dynamics of the ...
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. stocks plunged Tuesday as the prospect of higher-for-longer interest rates and letdowns from big-box retailers dampened the mood on Wall Street to start a busy holiday-shortened week.
A moving bed reactor has a fluid phase that passes up through a packed bed. Solid is fed into the top of the reactor and moves down. It is removed at the bottom. Moving bed reactors require special control valves to maintain close control of the solids. For this reason, moving bed reactors are less frequently used than the above two reactors.
Shares of retail giant Walmart (NYSE: WMT) were up a whopping 72% in 2024. To put the magnitude of this move in perspective, this was the best year for Walmart stock since 1998 -- you read that right.
Constellation Energy stock fell 12.5% Monday amid a broader decline in nuclear power stocks following the US government's rejection of another Big Tech nuclear power agreement late Friday.
Circulating fluidized bed technology can be implemented in many different fields ranging from oil and gas to power stations. This technology is highly sought after due to its numerous benefits. Some of the popular applications of circulating fluidized bed are circulating fluidized bed scrubber and circulating fluidized bed gasification system.
