The reactant or an inert fluid is at a space velocity sufficient to fluidize the catalyst beds.
The second stage temperature and space velocity are preferably greater than in the first.
Changing effective volume results in controllable residence time and/or space velocity.
In the method the inlet temperature is controlled based upon the space velocity of the gas stream through the reactor.
The composition of exhaust gasses input to the catalyst is also estimated using variables like engine load, engine speed, engine temperature and space velocity of the exhaust gases.
Two efficiencies are determined at least on the basis of the temperature of the storage-type catalytic converter (21) and on the basis of a spatial velocity.
One of the two efficiencies is determined for a high spatial velocity and the other efficiency is determined for a low spatial velocity.
Returns the spatial speed value at the specified time.
The storage efficiency is determined from both efficiencies on the basis of the actual spatial velocity.
The space vector is represented starting from a coordinate origin, and the derived parameters are based on the spatial path of the vector peak in the space around the coordinate origin and on the spatial velocity of the vector apex moving along the path.
The invention enables a high conversion with a good propylene yield, with a high spatial speed enabling the volume of the catalyst to be reduced.
The operating parameters of temperature, pressure, and spatial velocity of the DeN2O stage are selected in such a way that an N2O decomposition of 80 to 98% results.
Its observed radial velocity is −245 km/sec, and the components of its space velocity are U = 19 km/sec, V = −288 km/sec, and W = −52 km/sec.
2 Perform nearly all supported optimizations that do not involve a space-speed tradeoff.
GCC performs nearly all supported optimizations that do not involve a space-speed tradeoff.
Electrons having a spatial velocity function having negative curvature are produced by elastically scattering the electrons of an electron beam (113) from atoms at a specific energy.
The methods use a combination of molecular sieve catalyst and isomerization reaction temperature, and weight hourly space velocity to achieve the low levels of skeletal isomerization.
Ethylene/propylene ratio is changed in relatively large limits, 0.69-1.36, by the modification of reaction temperature and space velocity of the feed.
The weight-related space velocity relative to the hydrocarbons used is within the range of 0.1 to 20 h-1 and the temperature is 400 to 700° C.
The hydrocracking/hydrodesulphurisation conditions include a temperature of 450-580 °C, a pressure of 300-5000 kPa gauge and a Weight Hourly Space Velocity of 0.1-10 h-1.
