Batch autoclave work

Zinc Chloride Hydrocracking—Batch Autoclave Work. All tests were made in a 316 stainless steel, 300-ml rocking autoclave. The equipment, the product work-up, analytical and calculational procedures used are all identical to those previously described (1). A constant hydrogen partial pressure was used in each run by monitoring it with a palladium-silver alloy probe within the authoclave. The sensitivity of the probe response was increased as compared with prior work by heat treating at... 

Applications to batch processes have been less common, but there has been some work done on the use of an ANN to control autoclave curing. Joseph et al. used an ANN successfully to cure a part, reducing cure times and improving qualities, such as thickness control and void content [37], When more variables were included, however, the computational problem became intractable. This particular approach to using an ANN broke variables down into time, temperature, and pressure recipes, which, as noted in the Section 15.3.2, can lead to exponential growth of necessary training cases. 

A substantial program was also previously conducted in a batch autoclave unit on the direct hydrocracking of bituminous coal (1) with zinc chloride melts, but no work was done in either batch or continuous units on regeneration of spent melts from direct hydrocracking of coal. 

The present paper presents batch autoclave data on the direct hydrocracking of a single sub-bituminous coal from the Powder River basin of southeastern Montana. Comparative data were also obtained with the Pittsburgh Seam bituminous coal that was used in the previous work (I). Data on the regeneration of simulated spent melts from such an operation are also given in a continuous bench-scale, fluidized-bed combustion unit.
