Sentence examples for feeds catalyst from inspiring English sources

It is well-known that during the hydroprocessing of heavy feeds, catalyst aging is counterbalanced by continuously increasing reaction temperature.

It was observed that feeding ethylene monomer before zirconocene catalyst produced polyethylenes having much higher LCBD than feeding catalyst before monomer.

Particle size distribution of feed catalyst (m-1).

Procedures for pretreatment of feed, catalyst dispersion and sulfurization of catalyst precursors are also presented.

However, the system is very sensitive to small change in feed catalyst size, catalyst deactivation can cause build up of small polymer particles trapped in the system if the feed catalyst size is too low.

A hydrogen generation rate of 700 μM h− 1 (with 100 mg feeding catalyst) and a solar to hydrogen efficiency (STH) of 1.5% were achieved at 1.5 wt% of Ni2P.

Experiments have been carried out in a batch type reactor under the following conditions: 320 400 °C; 80 bar; feed:catalyst mass ratio, 20 1; LCO:HDPE mass ratio, 10 1.

It is also shown that due to the large polymerization rates exhibited in gas-phase olefin polymerization processes and to the near-well-mixed bed behaviour, the feed catalyst size distribution strongly affects the particle-size distribution in the bed.

All of the model parameters are temperature-invariant and are shown to apply to feeds and catalysts not too different from the base case.

We refer to Eqn. 4 as the feedback equation, because it says that the presence of catalysts feeds back into the polymerization rate and increases the rate of formation of more catalysts.

The effects of temperature, co-feeding ratios, feed-to-catalyst ratios and dual catalysts on hydrocarbon yields and selectivities were investigated.
