Background technology
In recent years, along with highlighting day by day of energy problem and environmental problem, human energy-conserving and environment-protective consciousness strengthens day by day.Current, polluting in the chemical industry has become a problem demanding prompt solution, and people hope to realize the atom economy of energy-conservation green, realize the zero release of pollution, adopt nontoxic raw material, the product that production environment is friendly.
China is a large agricultural country, and the YO of corn is up to 1.1～1.3 hundred million tons, and year reserves are also very high, reach 2,000 ten thousand tons.In the past, people do not recognize the utility value of corn cob, a large amount of corn cobs be used as carbon source burn or waste lose.In recent years, people utilize the acid hydrolysis technology in the middle of corn cob, to obtain wood sugar, obtain products such as Xylitol then through further deep processing.Glucose equally also is important hardware and software platform compound, and it can further pass through industrial biotechnology or catalysis technique, is converted into important fossil fuel and chemical such as ethanol, lactic acid, terepthaloyl moietie, glycerine, alkene or alkane.Therefore, utilize technology for hydrolyzing to have very big realistic meaning from corn cob production wood sugar and glucose.
Mainly be to adopt protonic acid (like sulfuric acid, hydrochloric acid etc.) liquid catalyst at present in the industrial production.They participate in chemical reaction with molecule (ion) form, and therefore quite high catalytic activity is just arranged under lower temperature.But have a series of problems when using this type catalyzer, as to the production unit seriously corroded, equipment requirements adopts expensive rotproofing; Difficult separate with reaction system, catalyzer can not recycle, produces to contain acid waste liquid in a large number, on technology, is difficult to realize continuous production; By product is many in the reaction process, the product purification difficult.Produce a large amount of solid waste-xylose residues in the corn cob hydrolysis reaction simultaneously, in factory, often be piled into the mountain, have a strong impact on environment, so the higher value application of xylose residue also is the problem of pendulum sternness in face of enterprise.
Scientists effort always at some new catalystsystem of research and development, hope the defective during overcome liquid acid catalyst uses.The appearance of solid acid catalyst has changed the reaction process of traditional liquid acid catalyst, with liquid acid catalyst compare have easily separated, reusable edible; By product is few; Low cost and other advantages all has very important significance at aspects such as development of resources, energy-conserving and environment-protective, from environment protection and energy strategy angle; If these liquid acid catalysts can replace with nontoxic solid acid catalyst, then aforesaid liquid acid problems just can be resolved.Therefore, replacing the liquid acid as catalyst with solid acid is an important channel of realizing environmental friendliness catalysis novel process.
People begin solid acid is studied for a long time, in the enterprising enforcement usefulness of industry, have made very big contribution to society like acid inorganic oxide solid strong acid (like zeolite, niobic acid, silica-alumina) etc.Recently; Carbon-based solid strong acid is developed and improves acid catalyzed performance; Reduce the catalyzer cost; This new catalyst can obtain the structure of poly aromatic hydrocarbons or with the charing of saccharide compound process, form the stable carrier with polycyclic aromatic hydrocarbons structure, then through sulfonation load sulfonic group through incomplete carbonization aromatic hydrocarbons.The preparation process of carbon-based solid strong acid is simple, has very high sour density and stability, in the green chemical industry process, has very big application potential.
Comprehensive existing document and patent report, what existing corn cob Mashing process mainly adopted all is liquid acid, and produces a large amount of solids liq wastes in the production process, this does not meet the theory of the environmental protection of being advocated at present.
