Gasoline-range hydrocarbons from catalytic cracking of rubber seed oil

Researchers at the Qingdao University of Science and Technology report producing gasoline-range liquid hydrocarbons from the catalytic cracking of rubber seed oil (RSO) using using USY (ultrastable Y zeolite) as a heterogeneous catalyst. A paper on their work is published in the journal Fuel.

Under the optimum cracking conditions of RSO 10 g, m(USY)/m(RSO) = 1:50, and 420 °C for 90 min, the yield of liquid product reached 75.6%. The chemical composition and properties of the liquid fuel were similar to those of gasoline-based fuels (C8–C9 content >70%, low acid value, good cold-flow properties, and high calorific value).

Experimental results showed that USY could be reused with negligible loss of activity over at least six cycles. The team concluded that USY appears to be a suitable heterogeneous catalyst for the production of liquid hydrocarbon fuels from RSO.
