20090069615 | METHOD AND EQUIPMENT FOR PREPARING ISOBUTYLENE USING TERTIARY BUTYL ALCOHOL - This invention discloses a method and equipment for preparing isobutylene using tertiary butyl alcohol. The equipment comprises a reaction vessel and a separating column. The upper portion of the separating column is fitted with a column top condenser, and the bottom of the column is fitted with a heater. The reaction vessel and the separating column are connected to each other by means of a pipe. One end of the dehydration column is connected to the heater at the bottom of the separating column, and the other end, after passing through a cooling unit, is connected to a distributor at the top of the separating column. A condenser with an outlet is connected to the outside of the said column top condenser. Isobutylene gas, which is generated as the solid superacid catalyst continuously reacts with and splits the tertiary butyl alcohol being introduced into the reaction vessel, flows together with boiling tertiary butyl alcohol gas into the separating column and is conducted by the distributor to the dehydrated extractant. Isobutylene gas flows out of the top of the column and passes through the condenser whereby it is cooled to become liquid isobutylene finished product. Unreacted tertiary butyl alcohol is condensed by the column top condenser to form liquid condensate, part of which is refluxed within the column and part of which flows out, returning to the reaction vessel. The dehydrated extractant passes through the distributor and enters the separating column from the top of the column. After the moisture in the rising gas is extracted and separated, it flows to the bottom of the column. After the dehydrated extractant has absorbed water, it is sent to the dehydration column where it is heated, the steam is separated from it, and the product is obtained. | 03-12-2009 |
20090078610 | METHOD OF TURNING VEGETABLE ASPHALT INTO SUPERIOR BOILER FUEL - This invention, which involves a method of turning vegetable asphalt into high-quality boiler fuel, belongs to the field of natural asphalt processing technology. It is intended for acid desaponification of vegetable asphalt at 50 to 100° C., then water washing is performed removing impurities and salt; following this, the asphalt is allowed to stand to separate into layers and the aqueous phase is removed. Neutralization to pH=7 to 8 is then performed using alkali and, after another water wash is performed, the asphalt is allowed to stand to separate into layers and the aqueous phase is separated from it. Then the substance obtained thereby is dried yielding the product. Vegetable asphalt that has undergone modification has the advantages of having low viscosity, generating a small amount of ash, having low sulfur content and a low flash point, and of not being prone to coking when it is burned, and the like, and ensures boiler heat efficiency and also prolongs boiler's useful life and reduces pollution. | 03-26-2009 |
