Polymethoxydialkyl ether (PODE) is a kind of oligoether compound which is produced by acetalization reaction. When both ends of poden are blocked by methoxy, it is called polymethoxydimethyl ether (dmm3-8, molecular formula CH3O (CH2O) nch3). Compared with DME and dmm1, dmm3-8 has higher viscosity and boiling point, so mixing with diesel does not need to change the existing engine Oil supply system. When the polycondensation molecular unit is controlled at n = 3-6, dmm3-8 has a good miscibility with diesel oil, with an average cetane number of over 76 and a boiling point of 156-268 ℃, which is just in the range of diesel oil. It overcomes the shortage of DME and dmm1 as fuel components, fully meets the requirements of clean diesel oil blending and components, and is considered to be a promising environmental protection diesel oil component.

Ethyl Acetate Plant and Process Technology There are 4 main prevailing processes for ethyl acetate production, i.e. Direct Esterification Process, Acetaldehyde Condensation Process, Ethanol Dehydration Process and Acetic Acid-Ethylene Addition Process. Each process has its advantages and its applicable services. Our process is based on reactive- distillation esterification, which is mature, low costing and suitable for those with acetic acid feedstock. Advantages of Our Ethyl Acetate Plant and Process Technology In our reactive distillation process, organic acid catalyst is used; its advantages cover the followings: Low ethanol consumption Low catalyst dosage High catalysis activity Low equipment corrosion Less side reactions

Each periodic ripple of the Zupak is composed of more than four intermittent planar graphic sheets located on four planes. The lateral projection shape is two interlaced corrugated lines. The uniform parallelogram channel on the filler has completely replaced the circular holes on the regular structured packing. It can not only save 8.5% of the material, but also increase the specific surface area of the corresponding quantity. The packing has the advantages of low pressure, large flux, good transversal air permeability and high separation ability. It can be widely used in the industrial fields of distillation, absorption, extraction, heat exchange, washing and so on. Compared to corresponding Mellapak packing, Zupak has advantages as follows: The specific area increases by around 10%; The porosity opening rate increases by 30-40%; The separation efficiency increases by about 10%;

PPC Technology Introduction PPC (polypropylene carbonate) is a completely biodegradable environment- friendly plastic synthesized from carbon dioxide and propylene oxide. Besides, due to its using the main source of greenhouse gases---CO2 as the feedstock, PPC not only reduces the emission of greenhouse gases, but also reduces the consumption of fossil fuel. Compared to the degradable PLA(polylactide), it has advantages of high strength, good ductility, lower production cost and etc. PPC polyol with low molecular weight are used to replace conventional petroleum-based polyether, polyester and polycarbonate polyols, while PPC with high molecular weight are employed as film products, oxygen barrier material, injection molding material and etc., especially in package industry and agriculture.

Hydrogen Peroxide Manufacturing Plant There are several methods for Hydrogen Peroxide Plant, among them the AO(auto- oxidation) process is the most prevailing one. In this process, 2-alkyl anthraquinone is mixed with organic solvent to make up the working solution, which is hydrogenated in presence of catalyst, and the resulting is oxidized by air (or oxygen) in counter-current way before being extracted, regenrated, purified and enriched to get commercial hydrogen peroxideproduct. Depending upon the different reactor type in the hydrogenation unit, AO process is further divided into Fixed Bed Reactor Process and Fluidized Bed Reactor Process. SL Tec provides both processes. For this hydrogen peroxide production technology, SL TEC cooperates with one of the branch companies of China National Chemical Engineering Co., Ltd.----- - SEDIN Ningbo Engineering Co., Ltd. to offer a turnkey hydrogen peroxide plant
