Publication number: 20170345029Abstract: A method and device for determining whether a user who has not ordered a commodity has a demand for the commodity. The method comprises calculating a number of actions directed at the commodity by users in a preselected time period that is not ordered in a preselected time period and a number of users purchasing the commodity after the preselected time period; establishing a training set based on the numbers and a model corresponding to the training set. The model has an input value of the number of actions directed to the commodity by a user and an output value of whether the user purchases the specified commodity. The method also includes calculating the number of actions of an object user who has not ordered in a preset time period and inputting the number into the model as the input value to obtain the output value of the model.Type: ApplicationFiled: December 8, 2015Publication date: November 30, 2017Inventors: Haiyong CHEN, Chuan MOU, Zhifeng XING

Publication number: 20170029739Abstract: The present application is directed to the preparation of low viscosity bio-oils from the hydrothermal liquefaction (HTL) of lignocellulosic biomass in the presence of a crude glycerol and water mixture achieving a high biomass conversion ratio. The modified HTL process allows the direct use of crude glycerol as an effective solvent for biomass liquefaction creating a highly efficient and cost-effective process. Furthermore, the resulting bio-oils containing liquefied biomass, crude glycerol and water, were successfully applied as an inexpensive green substitute in the preparation of bio-based phenol formaldehyde (BPF) adhesives which retain bonding strengths (dry or wet strength) as required by ASTM standard and free formaldehyde emission levels at the F*** and F**** level according to the JIS standard.Type: ApplicationFiled: July 28, 2016Publication date: February 2, 2017Applicant: Ace Econergy Inc.Inventors: Haiyong Chen, Chunbao Xu, Shanghuan Feng, Yan Wang
