Method for separating and recovering dimethyl terephthalate and ethylene glycol from polyester waste
Patent number: 6706843Abstract: For separation and recovery of dimethyl terephthalate (DMT) and ethyiene glycol (EG) from polyester waste containing foreign materials, the polyester waste is treated in EG containing a polyester depolymerization catalyst, a solid foreign material fraction floated on the surface of the resultant reaction solution is removed and the residual solid foreign material fraction is removed from the remaining solution fraction. The remaining solution fraction is distilled and concentrated and the distilled EG is recovered. A transesterification reaction catalyst and methanol are mixed into the distillation residue. The resultant reaction mixture is recrystallized and subjected to centrifugal separation to separate the reaction mixture into the DMT cake and a mixture solution, and then the cake is distilled whereby high-purity DMT is recovered. The residual mixture solution is subjected to distillation treatment for recovery of the methanol, and the distillation residue is distilled to recover EG.Type: GrantFiled: April 19, 2002Date of Patent: March 16, 2004Assignee: Teijin LimitedInventors: Kenichi Ishihara, Kenji Ishida, Masanori Miyamoto, Minoru Nakashima, Kazuhiro Sato, Hideo Hasegawa -

Patent number: 5183013Abstract: A two-cycle diesel engine and means for operating it to improve the performance by increasing the compression ratio by the closing of a supplemental exhaust port under light loads and low speeds. In order to reduce combustion chamber temperature and reduce nitrous oxide emissions, the injection timing is advanced an additional increment during the closing of the supplemental exhaust port. Various control strategies are described which involve either quickly raising the compression ratio and retarding the injection timing.Type: GrantFiled: September 28, 1990Date of Patent: February 2, 1993Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Hideaki Ito, Masanori Miyamoto

Patent number: 5178104Abstract: A diesel engine operating on the two cycle crankcase compression principle and having a means for reducing nitrous oxide emissions under low and medium range speeds. This is done by throttling the scavenge air flow which can be accomplished either by throttling the air admitted to the crankcase chamber or bypassing a portion of the compressed air from the crankcase chamber back to the induction system. In addition, an exhaust control valve is provided for raising the compression ratio and the injection timing is advanced when the scavenge air is reduced so as to further improve the control of hydrocarbon and carbon monoxide emissions.Type: GrantFiled: September 28, 1990Date of Patent: January 12, 1993Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Hideaki Ito, Masanori Miyamoto
