| Technique：OCT-M—FCC gasoline selective HDS |
| Country：[CN] |
Application Domain：[Technology for clean fuels production--gasoline ] |
| Brief： |
Background
FCC gasoline is of high contents of sulfur and olefins. Higher hydrogen consumption and higher octane number loss are the disadvantages of conventional HDS processes. OCT-M—FCC gasoline selective HDS technology is featured by selecting a suitable cutting point and cutting the FCC gasoline feed into two parts, then treating the light and heavy fractions separately. The light fraction normally has high olefin content and low sulfur content(most sulfur-containing substances are low carbon number mercaptans) and will be treated by caustic-scrubbing-extracting. The heavy fraction has high content of sulfur(especially thiophenic sulfur), it should be treated with specialty catalyst under mild operating conditions.
Features
✧ Feed can be of high sulfur, high olefin FCC gasoline
✧ Special HDS catalyst
✧ Mild operating conditions for heavy fractions
✧ High liquid yield(>99%)
✧ Low hydrogen consumption(0.2~0.3%)
✧ Proper cutting point
Aimed at
✧ Feed of FCC gasoline has high sulfur content(1000-1200ppm) and high olefin contents(30-40%) while sulfur content requirement to product is lower than 300ppm;
✧ Feed of FCC gasoline has moderate sulfur content(800-1000ppm) and moderate olefin contents(25-35%) while sulfur content requirement to product is lower than 200ppm;
Typical results
OCT-M—FCC gasoline selective HDS technology developed in FRIPP, SINOPEC has been put into commercial application in Guangzhou Petrochemical Company. Under reaction temperature of 200~300℃, pressure of 1.6~3.2MPa, LHSV of 3.0~5.0h-1 and H2/oil of 300:1~500:1(v/v), total sulfur removal rate can reach 85%~90%, olefins saturation rate can reach 15%~25%, RON loss is less than 2 units, (R+M)/2(antiknock index) loss is less than 1.5 units and liquid yield is more than 98m%.

| Technique：MCI----Maximal cetane improvement of poor quality diesel |
| Country：[CN] |
Application Domain：[Distillate Hydrotreating and upgrading] |
| Brief： |
R & D Background
MHUG can increase cetane number of poor quality diesel, but its diesel yield is relatively low. Hydrofining, on the other hand, can produce more diesel, but has limited capability in cetane number improvement (around 5 unit). In MCI process, poor quality diesel, particularly RFCC diesel undergoes deep HDS, HDN, olefin saturation, aromatics partially saturation/ring-opening and successive hydro -saturation (little cracking).
Features of MCI process
*Improve storage stability and considerably increase diesel’s cetane number by over 10 units.
*Diesel yield over 95m%
*Operating conditions and modes similar to existed hydrofining process, therefore, there is no, or little need for revamping existed hydrofining units to adopt MCI process.

| Brief： |
1,3-Propanediol (1,3-PDO) has numerous applications in the synthesis of polymers and other organic chemicals, such as, in carpet and other textile fibers. It is currently manufactured by chemical synthetic processes using petroleum derivatives, such as acrolein or ethylene. One potential method is via the fermentation of glycerol or glucose. At the present, FRIPP is making efforts to develop this fermentation technique for producing 1,3-Propanediol.
Biodesulfurization (BDS) is a process that removes sulfur from fossil fuels using a series of enzyme-catalyzed reactions. As environment regulations tighten on sulfur emissions, the amount of sulfur in petroleum products becomes an important issue. Therefore, efficient techniques of desulfurization are required. Recent years, FRIPP is working in biocatalytic desulfurization of petroleum distillates.

| Technique：Technique for Polyamide Hot-melt Adhesives |
| Country：[CN] |
Application Domain：[Bioengineering Technologies And Products] |
| Brief： |
Different DCA and their diamines converted with DCA, together with caprolactam, can be copolymerized to produce excellent hot-melt adhesives.
Synthesizing technology of copolyamides (nylon6/610/613 and nylon6/1010/613 Copolyamides) also has been developed by FRIPP. This kind of copolyamides is mainly used for hot-melt adhesive for costume manufacturing. During the research, software was applied to determine composition of copolyamides, and a mathematic model between composition and properties of hot melt adhesive was established. This model can be used to determine composition of product with different properties according to the demand of user. This technology has been granted Chinese patent in 1998. In FRIPP, a pilot-plant was established to produce polyamide hot-melt adhesives with different range of melting point. The main properties of products are listed in the table 3.

| Technique：Production of Long-chain Dicarboxylic Acid by Fermentation |
| Country：[CN] |
Application Domain：[Bioengineering Technologies And Products] |
| Brief： |
Long-chain dicarboxylic acid is a kind of organic acid that contains eight or more carbon-atoms and two carboxyl functional groups, witch is usually called DCA. Its general formula is:
HOOC -(CH2)n-COOH n≥6
A series of DCA, ranging from DCA10 to DCA18 can be produced by fermentation from correspond n-paraffin. The conventional production methods based on chemistry have been replaced by fermentation methods, which have the characteristics of high efficiency, mild conditions and good availability of raw materials, etc. It is an important application of biotechnology in petrochemical industry.
DCA are high-tech products with excellent application prospects because of their low cost and high output value. For example 1,13-tridecanedioic acid (DCA13, Brassylic acid) is a very important chemical intermediates, which is mainly used as feedstocks for preparation of perfume, hot melt adhesive, engineering plastics and high quality lubricants, etc. With the increasing demand for these down-stream products, the need for DCA is also increasing steadily.
The main raw material for producing DCA by fermentation is n-paraffin, which can be obtained from petroleum paraffin by distillation.
Since 1986, FRIPP has made great progress on the research of DCA fermentation and the development of its down-stream products. The fermentation conditions were studied in laboratory fermentor and in pilot plant. Now a commercial plant with 150t/a capacity has been set up to produce a series of DCA. The quality of tridecanedioic acid is listed in table1.

Abstract
Supergravity strengthens mass transfer process by using strong centrifuge field instead of gravity field, which has gained wide attention at home and abrosd since it came out last century. But most of the work has been in basic application research, reports on commercial application are little. Beijing Xinte Technology Development Company has successful applied this technology in deodorizating thermal sensitive matter, producing superfine powder and hydrogenation process, and a commercial demonstration facility has been built.
