Schematic of the fixed bed reactor system Download Scientific Diagram
Residue hydrocracking has been attracting more and more attention to the refining industry in recent years, and one of the best approaches is ebullated bed residue hydrocracking (EBRH). STRONG ebullated bed residue hydrocracking uses a new type of reactor, and a 50 KTA demonstration unit has been put into operation now. Crucial points of STRONG residue hydrocracking are proposed physical and.

This work aims to design a multi-tubular fixed-bed reactor, which is able to convert a carbon dioxide stream into Synthetic Natural Gas (SNG) in an optimal manner. For this purpose, carbon dioxide is mixed with hydrogen in stoichiometric ratio ( n ̇ H 2 ∕ n ̇ CO 2 = 4 ∕ 1) and fed to the multi-tubular reactor.

The paper develops a design feasibility study of a multi-tubular polytropic fixed bed reactor for the one-stage ethanol to 1,3-butadiene (ETB) process employing a modified MgO-SiO 2 catalyst. The analysis quantifies the effect of the internal diffusion on scaling up the catalyst activity and selectivity by considering a complex chemistry of seven parallel/series reactions described by detailed.

The membrane reactor technology, where the steam reforming, water gas shift and hydrogen purification steps all take place in a single reactor, is a promising alternative. Membrane reactor consists of a multi-tubular fixed bed reactor equipped with a hydrogen-selective membrane [58,59]. Methane and steam are fed into the reactor under pressure.
Patent US7226567 Multitube fixedbed reactor, especially for catalytic gas phase reactions
These are the multi-tubular fixed-bed, the slurry reactor, or the fluidized-bed reactor (with either a fixed bed or a circulating bed). The fixed-bed reactor consists of thousands of small tubes with the catalyst as surface-active agent in the tubes. Water surrounds the tubes and regulates the temperature by settling the pressure of evaporation.

reactors with a commercial multi-tubular packed-bed reactor for methanol synthesis. They concluded that the packed-bed reactor had a better performance than structured systems due to the e ective convective heat transfer mechanism in the catalyst bed, which is shown as lower hot-spot temperatures and higher radial heat transfer rates.
Fixed bed Tubular reactors
The power-to-gas (PtG) technology has been known as one of the most viable solutions for storing intermittent renewable energy sources such as solar and wind to the existing gas grid. The chemical CO 2 methanation in a fixed-bed multi-tubular reactor was studied via a multi-scale optimization (MSO) approach covering an one-dimensional plug-flow.

The multi-tubular fixed bed reactor is traditionally used for the production of acrolein and acrylic acid from propylene. Commercially the propylene oxidation reaction is accomplished in two stages, namely, propylene oxidation to acrolein followed by acrolein to acrylic acid using different catalysts at each step [].Propylene is one of the most important chemical raw materials and it is widely.
