Ramsbottom Carbon Residue of Petroleum Products

Test Method
Determines the ‘carbon residue’ left after evaporation and pyrolysis of a sample oil in the Ramsbottom furnace, providing an indication of the deposit forming tendencies of fuels and guidelines for the processing of refinery products.

Ramsbottom Carbon Residue Apparatus
Conforms to ASTM D524 and related specifications
Microprocessor temperature control with digital display and overtemperature cut-off

Thermostatically controlled coking furnace for five samples. Cast-iron block type furnace reaches the standard test temperature of 550°C (1022°F) rapidly and controls with ±1°C stability. Microprocessor temperature control has °C/°F switchable digital setpoint and display. Operator and equipment are protected by an overtemperature control circuit which automatically interrupts power to the unit should block temperature exceed the programmed cut-off point.
Communications software (RS232, etc.), ramp-to-set and other enhanced features are available as extra cost options. Heavily insulated stainless steel cabinet with three-layer refractory top provides excellent heat retention.
