The coke for synthetic graphite is also calcined before further processing. It is calcined until a sample of —35 + 100 mesh material shows an electrical resistivity of less than 0.05 ohm-inch. The same type of calciners are used that are used to calcine coke for the aluminum industry (29). The calcined coke retains a major portion of the sulfur present in the green petroleum coke (1). Low-sulfur, green coke is preferred. 

Other undesirable components of both petrol and diesel fuel are sulfur-containing compounds that may be present in small quantities. These give rise to sulfur dioxide in the exhaust gas. In addition to being another acid pollutant, it is also detrimental to the life of the catalytic converter. Consequently, the principal petroleum companies have developed and brought to the market ultra-low sulfur ( green ) petrol and diesel. The action to reduce dramatically sulfur levels in motor fuel has also been made in response to regulations in the USA and the European Union.
