    Abstract: The present invention provides a production method of biodegradable plastic in which polylactic acid is directly synthesized from lactic acid without employing the conventional route of polylactic acid synthesis from lactic acid via lactide, and apparatus for use in production thereof. In this way, time required for the synthesis of polylactic acid is strikingly shortened and the production cost is reduced. In the production method of biodegradable plastic, polylactic acid, the main component of biodegradable plastic, is obtained by means of condensation polymerization by dehydration of the raw material, lactic acid, under high temperature and reduced pressure in the presence of a metal catalyst.

    Abstract: An apparatus and a process for reclaiming fuel oils from waste oils. The apparatus and process is characterized in that waste oils are thermally cracked by combination of high pressure and vacuum in a sequence at high temperature. However, rapid thermal cracking is performed at even lower temperature of 300˜350° C. than at 400˜450° C. of conventional batch method. The semi-continuous method with bleeding process is employed and accordingly no pause stage becomes necessary to physically collect ash cake from the thermal cracking vessel as experienced from the conventional batch process. The ash cake contents drops from 5% of conventional method to 1.4% since slow reaction is a cause for oxidation problem which is related with formation of tar compounds and production rate of #2 diesel fuel oil increases 3 times more than batch process.

    Abstract: An exemplary apparatus facilitates the formation of carbon nanotubes with desired tip structures. The apparatus includes a reaction chamber including a gas outlet, and an evacuation device. The reaction chamber is configured for receiving a catalyst from which the carbon nanotubes grow and providing an environment for growing the carbon nanotubes. The evacuation device includes an intake connected with the gas outlet. The evacuation device is configured for reducing an inner pressure in the reaction chamber and inducing the formation of carbon nanotubes with desired tip structures. Methods for synthesizing carbon nanotubes with desired tip structures are also provided.

    Abstract: A batch-type polyester polymerization apparatus manufactured by assembling a conventional batch-type apparatus with a thin film tower. The batch-type polyester polymerization apparatus is advantageous in that oligomer is polymerized while forming a polyester thin film on each inclined plate of a thin film tower, and a polycondensation reaction is conducted in a polycondensation reactor as well as the thin film tower, thus greatly reducing polymerization time.

    Abstract: A chlorine dioxide generator comprising a primary vessel and a canister which is attached to a receptacle at the bottom of the primary vessel and functions as a reaction vessel. A signal is generated to indicate when the canister is securely in place and a solenoid rod locks the canister in position until a chlorine dioxide reaction goes to completion. To start the reaction, water fills a priming chamber and solution chamber of the primary vessel, the priming chamber being located in an upper portion of the primary vessel, and an air pump forces a predetermined portion of water from the priming chamber via a feed line through a grommet at the top of the canister to a chemical reaction chamber of the canister along with a continuous air flow. The water from the feed line contacts precursor chemicals within the canister and chlorine dioxide gas is generated which passes through a gas flow chamber and into the primary vessel via a gas membrane valve.
