Reactor Advanced Cracking

Advanced Cracking Reactor. The selectivity to olefins is increased by reducing the residence time. This requires high temperature or reduction of the hydrocarbon partial pressure. An advanced cracking reactor (ACR) was developed jointly by Union Carbide with Kureha Chemical Industry and Chiyoda Chemical Constmction Co. (72). A schematic of this reactor is shown in Figure 6. The key to this process is high temperature, short residence time, and low hydrocarbon partial pressure. Superheated steam is used as the heat carrier to provide the heat of reaction. The burning of fuel... 

ACR [Advanced Cracking Reactor] A thermal petroleum cracking process, the heat being provided by partial combustion of the feed at 2,000°C. Developed by Chiyoda Chemical Engineering Construction Company, Kureha Chemical Industry Company, and Union Carbide Corp. in the 1970s. A demonstration plant was operated in Seadrift, TX, from 1979 to 1981.

The Advanced Cracking Reactor (ACR) is an autothermal reactor where hydrocarbon feed and diluent are mixed with oxygen in order to partially oxidize the hydrocarbons and provide the heat for the pyrolysis reaction. High temperatures and very short contact times are achieved before a rapid direct quench by oil injection (Kearns et al., 1979).
