White cement and burnt brick powder catalyzed .

The catalytic pyrolysis produced 95.50% and 93.15% oil with white cement catalyst and brick powder catalysts, respectively. It seems that the yield of liquid product of noncatalyzed pyrolysis is almost the same as the catalytic pyrolysis. It is worth mentioning here that the optimum time for noncatalytic pyrolysis was 45 min, which is much higher than the optimum time of catalytic pyrolysis ...

In both cases, the dry cement 'powder' is pumped into tankers under air pressure to ensure the maximum volume can be shipped, and that the chance for any product to escape is greatly reduced. Once it reaches its destination, the cement is then pumped (again under air pressure) into storage silos where it is held until required. In regional areas, this can occur several times as the product ...
