BEIJING, July 23 (Reuters) -Malaysian palm oil futures rose on Tuesday for a sixth consecutive session, the market's longest rally since January, lifted by strong exports in July so far.

The benchmark palm oil contract FCPOc3 for October delivery on the Bursa Malaysia Derivatives Exchange gained 28 ringgit, or 0.7%, to 4,013 ringgit ($858.03) a metric ton during early trade, touching its highest since July 5.
