本文以木糖加氢在高温高压的条件下的工艺流程为主要研究对象，通过选择催化剂的种类来确定反应的最佳效果，通过调节反应过程中催化剂的用量来确定反应的速率，通过控制温度和压力找出反应效果最佳时候的反应条件，通过改变木糖液的PH找出反应效果最佳时候的PH。最后的优化结果为：选用骨架镍为催化剂，用量在反应液的3％～6％，温度控制在110～130℃，压力在7MPa左右，溶液的PH为8。
根据优化结果，得出最优的设计方案，对塔、换热器、储罐和泵等设备进行设计。然后完成设备布置的设计和配管的设计，绘制带控制点的工艺流程图、车间布置图、配管图和工艺设备图。

Hydrogenation xylose in this paper under the condition of high temperature and high pressure of the process as the main study, by choosing the type of catalyst to determine the best response, in the reaction process by regulating the amount of catalyst to determine the rate of reaction by controlling the temperature and the effect of pressure to find the best reaction time of reaction conditions, by changing the PH-sugar reaction to identify the best effect when the PH. Optimization of the final results: Selection of Raney nickel as the catalyst in the reaction solution volume of 3% to 6%, the temperature controlled at 110 ~ 130 ℃, about 7 MPa pressure in the solution of PH 8.
According to optimize the results of optimal design of the towers, heat exchangers, storage tanks and pumps, and other equipment design. Then complete the design and equipment layout of piping design, drawing process with the control point plans, the shop layout, piping map and the map of equipment.
