A two-stage synthesis gas preparation system and method complementary to biogas and solar energy

Abstract

A two-stage syngas preparation system and method complementary to biogas and solar energy, the system includes: a first three-way valve, a second three-way valve, a primary regenerator, a primary reactor, a third three-way valve, Secondary recuperator, secondary reactor and solar collector. The desulfurized biogas is divided into the first part of desulfurized biogas and the second part of desulfurized biogas; the first part of desulfurized biogas and water vapor are mixed and preheated, and then the heat energy converted from solar energy is absorbed in the primary reactor and generated Reforming reaction to generate reforming reaction products; the reforming reaction products are cooled and mixed with the second part of desulfurized biogas, after preheating, the heat energy converted from solar energy is absorbed in the secondary reactor and the reforming reaction occurs, cooling After output. The invention improves the grade of thermal energy of solar energy to the grade of chemical energy of syngas by integrating solar heat collection and two-stage biogas reforming, reduces water consumption, and improves the economical efficiency of biogas and solar energy utilization.

Description

technical field [0001] The invention relates to the field of solar energy utilization and energy technology, and in particular to a two-stage syngas preparation system and method that integrates key unit technologies such as solar heat collection and biogas reforming, which are complementary to biogas and solar energy. Background technique [0002] my country is rich in biomass resources, and biogas has become an important way to utilize biomass. my country's biogas generation system has borrowed from foreign mature technologies and has developed in the direction of large and medium-sized biogas generation systems; however, biogas utilization technology is relatively backward, and biogas utilization efficiency is low Low problem. The complementary utilization of multiple renewable energy sources has the potential to improve energy utilization efficiency and energy supply quality, and reduce energy supply costs, and has become a hot technology in the field of renewable energy....
