WebThis experimental set-up allows operation conditions (temperature, catalyst-to-oil ratio and residence time) to be varied over large ranges. The feed was injected through a septum … Modern high-pressure thermal cracking operates at absolute pressures of about 7,000 kPa. An overall process of disproportionation can be observed, where "light", hydrogen-rich products are formed at the expense of heavier molecules which condense and are depleted of hydrogen. The actual reaction is known as homolytic fission and produces alkenes, which are the basis for the economical…
