Hydrogenation Liquid Product and Hydrogen Atmosphere

A plant in Germany was modified to accept ground-up plastic wastes as a partial feed. The plant, originally built to process coal to synthetic fuel, had been converted to oil sludge upgrading. The process has been described as follows [42]  

The unit recycles up to 40,000 metric tons per year of mixed plastic containing up to 10% PVC. Up to 20% of its feed will be mUled plastic particles less than 8 mm in diameter. [The] unit operates at 150-300 bars and about 470°C in a hydrogen atmosphere, producing a syncrude containing 60% paraffins, 30% naphtha, 9% aromatics and 1% olefins. Chlorine... is converted to HCl in the reactor, then neutralized with calcium carbonate.
