Abstract
A process for preparing the biodegradable oil absorbing material from polyhydroxy aliphatic ester (PHAs) as principal raw material is disclosed. The said oil absorbing material may be powder, plate, barrel, fibres, felt, etc. and features high plasticity, easy machining, and high lipophilicity and hydrophobicity.
Description
The present invention relates to environment protection and novel material application category, relate in particular to polyhydroxyalkanoate (PHAs) as the application of oil absorption material in removing degreasing, utilize polyhydroxyalkanoate as oil absorption material remove smeary method and a kind of described oil absorption material with the preparation method.
The oil absorption material purposes is very extensive.But this class material of producing is the artificial-synthetic copolymer's oil absorption material based on poisonous and hazardous petrochemical materials mostly at present, as polypropylene fibre, nylon, urethane, polyethylene, polypropylene etc., these matter-pole difficult for biological degradation, have in addition in hundreds of year, all can not degrade.Dispose very difficultly after these material oil suctions, can produce toxic and harmful such as oxynitride and Dioxins etc. after the burning, cause serious secondary pollution.Therefore need new oil absorption material to overcome above-mentioned shortcoming.
The applicant finds that PHAs is a kind of 100% Biodegradable material, its goods can be in environment by means of action of microorganisms natural degradation, speed is very fast during burning, intermediate product is few.PHAs plasticity-is strong, and easily machine-shaping and have very good lipophilic-hydrophobic property can absorb various oil plants, lubricating grease and other water water-soluble organic compounds fully, and absorption can reach capacity in tens of seconds.This biological green material is spotless and flawless, nonpoisonous and tasteless, meets the engine hygiene requirement fully.
According to an aspect of the present invention, provide polyhydroxyalkanoate as the application of oil absorption material in removing degreasing.In above-mentioned application, described polyhydroxyalkanoate is gang's macromolecular material, and its general structure is:
N=1 wherein, 2,3,4; R is positive alkyl group side chain, scope from methyl to nonyl.
According to the present invention, a kind of deoiling method also is provided, comprise that the environment-friendly type oil absorption material that will utilize polyhydroxyalkanoate for the fully biodegradable of feedstock production is applied to the greasy dirt source, wherein said polyhydroxyalkanoate is gang's macromolecular material, and its general structure is:
N=1 wherein, 2,3,4; R is positive alkyl group side chain, scope from methyl to nonyl.
According to the present invention, it is the method for the environment-friendly type oil absorption material of feedstock production fully biodegradable with novel material one polyhydroxyalkanoate of biofermentation technique production that a kind of utilization is provided, its principal character is: the basic raw material of this environment-friendly type oil absorption material be polyhydroxyalkanoate (polyhydroxyalkanoates, PHAs).
Described polyhydroxyalkanoate raw material utilizes biofermentation technique production, comprise adopting various types of microorganisms (comprising genetic engineering bacterium) fermentative preparation or adopting gene plant to produce polyhydroxyalkanoate and (comprise and adopt various raw material, as starch, rice, glucose, molasses, hydro carbons, alcohols, transgenic plant, CO
2, H
2, O
2Deng).These technology are seen CN1190674A and industrial microorganism, 1997 the 27th volumes, the 3rd phase, 37-41 page or leaf.
As environment-friendly type oil absorption material of the present invention, with polyhydroxyalkanoate is unique or main raw material prepares the oil absorption material of complete biodegradable, and the concrete form of material can be the powder, foaming plate, tube material of different diameter, thread or hollow filamentary fibers or asphalt felt, oil suction bag, oil absorbent piece etc.
Method of the present invention can be applicable to the recovery of sea or waters, land water surface oil spilling, and oily(waste)water is handled, and engineering shop's oil pollution is removed, the kitchen fume smeary purifies, harbour, harbour Pollution abatement, the auto repair cleaning oil pollution, petrochemical complex is polluted control etc.
PHAs is a kind of ideal oil absorption material of compliance with environmental protection requirements, adopts this material can process the oil absorption material of various different shapeies and requirement, and method is as follows:
With the PHAs attrition process, can make the PHAs oil absorptive pulvis (pulvis of different-grain diameter is suitable for the absorption of different oil products) of various different-grain diameters, PHAs material heating melted and sprayed to make PHAs filamentary fibers oil absorption material, with its filamentary fibers one step processing, can be made into PHAs asphalt felt or oil absorbent piece.Also can the screen cloth bag PHAs pulvis be packaged into bag or rectangular ropy, make oil suction bag or wick.
In addition, can adopt the industrial chemicals of PHAs main raw material and a little synthetic, for example congruent melting such as polyolefine such as polyethylene, polypropylene or polyester such as urethane and make toughness and the mixture oil absorption material that the single PHAs material of strength ratio is bigger and the oil suction goods of different shape thereof, this mixing material has very high biodegradability, and its environmental hazard reduces greatly than single synthetic chemistry oil absorber.
The present invention will be described with embodiment below, but and do not mean that limitation of the invention.
Embodiment:
Present embodiment adopts most typical two kinds of polymkeric substance in the PHAs family material: poly-beta-hydroxy-butanoic acid ester (being called for short PHB) (weight-average molecular weight is 45000) and beta-hydroxy-butanoic acid-valerate multipolymer (being called for short PHBV) (weight-average molecular weight is 54000) experimentize.
Adopt the microscreen sheet that particle diameter is sewn into circular bag greater than 40 orders and particle diameter greater than each 2 gram packing of two kinds of PHAs pulvis of 200 purposes, with light crude draw up the water surface oil spilling, to absorb in the PHAs oil suction bag placement water surface light crude, and produce ECOSOL board oil suction pulvis with Holland and do reference, the oil suction situation is as follows:
*Oil absorption test ties up to and carries out under 18 ℃ of the room temperatures;
*The oil suction gram number of every gram material.
| Project * | Oil absorption material | ||
| PHBV pulvis bag (＞40 order) | PHBV pulvis bag (＞200 order) | ECOSOL pulvis bag (Holland produces) | |
| The saturated oil suction time (second) | ??40 | ??40 | ?30 |
| Saturated oil number (g/g **) | ??9.4 | ??6.6 | ?11.7 |
Adopt beta-hydroxy-butanoic acid-valerate multipolymer (being called for short PHBV) to test, obtain similar result.
