embodiment

[0068]In an embodiment of the invention illustrated in FIG. 1, a heavy hydrocarbon feed stream 101 and a water feed stream 103, having compositions as shown in TABLES 1 & 2 (Simulated Example Data), are fed to a mixer 130. As described in more detail above, the mixer 130 may include, but is not limited to, static mixers, spray nozzles, and sonic or ultrasonic agitation. The heavy hydrocarbon feed stream 101 and the water feed stream 103 are mixed so that a combined stream 104 will reach supercritical water conditions. The operating pressure of the mixer 130 is in the range of about 3250 to about 3600 psia. The operating, temperature of the mixer 130 is in the range of about 385 to about 420° C. The oil / water mass mix ratio of the mixer 130 is in the range of about 1:0.5 to about 1:3.

[0069]The combined stream 104 is fed to a reactor 140. The combined stream 104 has a composition as shown in TABLES 1 & 2. As described in more detail above, the reactor 140 may include, but is not limit...
