ORGANIC WASTE RECYCLING APPARATUS, AND RECYCLING METHOD THEREFOR
An organic waste recycling apparatus comprises: a catalyst for making the carbonization of an organic waste targeted for waste disposal; a UV irradiation member for irradiating UV at a wavelength capable of breaking a bond in a molecule constituting the organic waste; a processed object housing member whereof the interior space houses the catalyst; a heating member provided in the interior space; and a stirring member provided in the interior space. The organic waste is one that has undergone crushing into small pieces. The processed object housing member is such that the catalyst and the organic waste that has been UV-irradiated by the UV irradiation member and introduced into the interior space are in contact with one another and stirrable in this state by the stirring member.

USE OF HETEROGENEOUS ACID CATALYSTS BASED ON MIXED METAL SALTS TO PRODUCE BIODIESEL
The present invention relates to the production of biodiesel and alkyl esters by the transesterification of triglyceride esters, with alcohols in heterogeneous phase in the presence of heterogeneous catalysts, with yields higher than 80%, at a temperature from 0 to 300° C., residence time from 20 minutes to 20 h, space velocity of 0.1 to 10 h.sup.−1, pressure of 25-100 kg/cm.sup.2 (24.5-98.07 bar), methanol/oil molar ratio of 10 to 40 and catalyst concentration of 0.001 to 20 weight % based on tri-, di- or monoglyceride. The method produces biodiesel and alkyl esters by transesterification of tri-, di- or mono-glycerides, from palm, jatropha, castor, soybean and sunflower oils, wherein the alcohoxyls R.sup.1O, R.sup.2O and R.sup.3O of the glycerides are C.sub.1 to C.sub.24 and a C.sub.1-C.sub.4 alcohol, such as methanol, in an alcohol:oil ratio from 3:1 to 50:1. The transesterification reaction produces biodiesel while avoiding loss of catalyst, contaminating liquid effluents and eliminating undesirable hydrolysis of triglycerides, diglycerides and monoglycerides into free fatty acids and saponification that generate soaps.
Low 4-methylimidazole (4-Mel) caramel color class IV production
The application pertains to a process comprising a) acidifying a carbohydrate to a pH below 2; b) heating the mixture from step a) to a temperature from about 60° C. to about 100° C.; c) adding a catalyst to the mixture from step b) over a time from about 10 minutes to about 200 minutes; d) heating the mixture from step c) to a temperature from about 121° C. to about 140° C. and to a pressure of about 4.5 Kg/cm.sup.2 to about 5.3 Kg/cm.sup.2 over a time from about 15 minutes to about 90 minutes; and e) maintaining the mixture of step d) at a temperature from about 121° C. to about 140° C. and a pressure of about 4.5 Kg/cm.sup.2 to about 5.3 Kg/cm.sup.2 over a time from about 1 minute to about 300 minutes.
Selenium-containing hydroprocessing catalyst, its use, and method of preparation
A hydroprocessing catalyst composition that comprises a support material and a selenium component and which support material further includes at least one hydrogenation metal component. The hydroprocessing catalyst is prepared by incorporating a selenium component into a support particle and, after calcination thereof, incorporating at least one hydrogenation metal component into the selenium-containing support. The metal-incorporated, selenium-containing support is calcined to provide the hydroprocessing catalyst composition.
SYNTHESIS AND APPLICATION OF ALCOHOL AMINE WITH EXTENDED MAIN CARBON CHAIN
Synthesis and application of an alcohol amine with an extended main carbon chain are provided, belonging to the field of chemical building materials. Under the action of a catalyst, tertiary amine is subjected to a two-step substitution reaction, a hydrolytic reaction and a reducing reaction to obtain a novel alcohol amine (NAA). The novel alcohol amine as provided may have a better grinding aid effect than triethanolamine while is added into cement as a cement grinding aid, and thus has a wide application prospect.
