  • Oil adsorbent and process for preparation thereof
    Patent number: 4209382
    Abstract: An effective and regenerable oil adsorbent is obtained from a pitch-like substance formed by heat-treating a heavy hydrocarbon oil to such an extent that the volatile matter content thereof is about 10% by weight to about 60% by weight, preferably about 30 to about 50% by weight. By using this oil adsorbent, oil-removing purification treatment of oil-contaminated water can be effectively achieved with economical advantages.
    Type: Grant
    Filed: February 15, 1978
    Date of Patent: June 24, 1980
    Assignee: Koa Oil Co., Ltd.
    Inventors: Kosaku Noguchi, Kiyoharu Yoshimura, Honami Tanaka, Masao Hayashi
  • Process for preparation of high quality coke
    Patent number: 4100265
    Abstract: High quality coke is prepared by calcining green coke obtained by the delayed coking process at a temperature lower than the customarily adopted calcination temperature, once cooling the coke and then calcining the coke at a temperature within the customarily adopted calcination temperature range.

  • Process for continuous production of pitch
    Patent number: 4080283
    Abstract: Pitch is produced continuously by heat treating a heavy hydrocarbon oil at a temperature of 350.degree. to 500.degree. C successively in two or more reactors connected in series, outlet to inlet, recirculating, at the same time, one portion of the liquid output substance from at least one reactor into that reactor, and introducing the output substance (molten pitch) of the final reactor into an after-treatment chamber of duct shape with an inactive atmosphere sealed therewithin thereby to cool the output substance.
