Coal: Coal liquefaction data

Description Format Source Examples

Description

The Coal data frame has 23 rows and 20 columns of data on a coal liquefaction process.

Format

This data frame contains the following columns:

Time

the time of the observation, measured from the beginning of the run (min).

temp

the temperature of the run (K).

pressure

the pressure at which the run was performed (MPa).

fe2o3

iron oxide? (Fe2 O3) concentration in the run (wt% maf).

tr

transfer rate of the feed (wt% maf).

x1

inlet composition of unconverted coal (wt %).

x2

inlet composition of thermal residuals (wt %).

x3

inlet composition of C4-822K (wt %).

x4

inlet composition of C1-C3 gases (wt %).

x5

inlet composition of byproduct gases (wt %).

x6

inlet composition of water (wt %).

x7

inlet composition of hydrogen (wt %).

x8

inlet composition of Coal (wt %).

y1

outlet composition of unconverted coal (wt %).

y2

outlet composition of thermal residuals (wt %).

y3

outlet composition of C4-822K (wt %).

y4

outlet composition of C1-C3 gases (wt %).

y5

outlet composition of byproduct gases (wt %).

y6

outlet composition of water (wt %).

y7

outlet composition of hydrogen (wt %).
