摘要： The present invention relates to a polymerizable phosphonate monomer and a preparation method therefor, a copolymer prepared and obtained from the polymerizable phosphonate monomer and a drilling fluid that uses the copolymer. The anion of the polymerizable phosphonic acid (salt) has a structure that is represented in the following formula (1), and the cation is at least one among hydrogen, a monovalent metal cation, a divalent metal cation, a trivalent metal cation, and a tetravalent metal cation. In addition, 1H NMR of the polymerizable phosphonic acid (salt) substantivelysubstantively has no peak at the chemical shift δ of 1.019. The preparation method for a polymerizable phosphonic acid (salt) monomer as provided in the present invention uses an organic solvent as the solvent of a reaction system, so that compared to a water solvent system, reaction efficiency is higher, less by-products are produced, and the separation of the obtained products is simpler. Moreover, the obtained product has higher purity, and thus a copolymer having higher molecular weight may be obtained, and the temperature and salt resistance of the drilling fluid can be improved.

摘要： Disclosed is a starch-containing microsphere and a preparation method thereof and an application thereof. The particle size of the starch-containing microsphere exhibits polydispersity with uniform distribution in a particle size concentrated distribution interval, and the particle size distribution in the particle size concentrated distribution interval has the following features: equal division of the particle size concentrated distribution interval into n intervals, and a microsphere percentage in each interval is (I), where n is an integer greater than 1. The preparation method comprises: first reacting starch with a low concentration of epichlorohydrin, and then reacting the resultant product with a surfactant, followed by final crosslinking to give microspheres. The starch-containing microspheres prepared by the present invention are polydisperse starch-containing microspheres with a uniform particle size distribution, with the particle size being in a range of 0.1-500 µm. 100 n % ± 10 n %

摘要： A process and apparatus for producing lower carbon olefins and BTX by catalytic pyrolysis of hydrocarbon-containing feedstock oil, and the process comprises the steps: cutting the hydrocarbon-containing feedstock oil into a light distillate oil and a heavy distillate oil; introducing the light distillate oil and a first catalyst into a down-flow reactor to perform a catalytic pyrolysis to produce a stream after the first catalytic pyrolysis; subjecting the stream after the first catalytic pyrolysis to a gas-solid separation to produce a first reaction hydrocarbon product and a first spent catalyst; or, introducing the stream after the first catalytic pyrolysis into a fluidized bed reactor to perform a catalytic pyrolysis, and then subjecting to a gas-solid separation to produce a second reaction hydrocarbon product and a second spent catalyst; introducing a continuous catalyst, the heavy distillate oil and a second catalyst into an up-flow reactor to perform a catalytic pyrolysis, and then subjecting to a gas-solid separation to produce a third reaction hydrocarbon product and a third spent catalyst; separating out lower carbon olefins and light aromatics from reaction hydrocarbon products, and separating out a light olefin fraction, and returning the light olefin fraction to the fluidized bed reactor or the up-flow reactor. The process can significantly increase the yields of lower carbon olefins and light aromatics as well as the economy of the apparatus.
