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 ...
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 ...
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.
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 ...
For Walmart to reach a $1 trillion market cap, it would need to rise by 37% from where it is today. That would likely mean another strong year of outperforming the market by a wide margin.
A bubble column reactor is a very simple device consisting of a vertical vessel filled with water with a gas distributor at the inlet. Due to the ease of design and operation, which does not involve moving parts, they are widely used in the chemical , biochemical, petrochemical , and pharmaceutical industries to generate and control gas-liquid ...
Quantum computing stocks rebounded Tuesday after a massive sell-off fueled by Big Tech CEOs expressing skepticism. The stocks recovered as D-Wave CEO Alan Barrett said quantum computing is "real."
